[hallow quail]

1/(1/x) = x

[hasty current]

oops

x^-1

[hallow quail]

hm

no harm in trying

y = 1/x

xy = 1

take the derivative of both sides, 1 --> 0 (constant disappears)

xy is a product rule (+ chain rule / implicit differeination)

so left d right + right d left

x dy/dx + y = 0

isolate dy/dx

dy/dx = -y/x

y = 1/x

so dy/dx = -1/x^2

YEP now that was awesome @hasty current

[hasty current]

indeed

[hallow quail]

i never thought of using this method with negative powers like that

ty for saying this

🫡

[hasty current]

ofc

[wanton prairie]

Hi

[lost forum]

Do (6/log(x))'

[empty walrus]

@hybrid depot fancy seeing you here

[austere cipher]

Hello discusser 2

[hybrid depot]

Oh wait

So you're also in here

[empty walrus]

Just got in today

[hybrid depot]

Lmao

[empty walrus]

Someone tried to brainfuck me with math

It worked

[hybrid depot]

What

Lmao

[empty walrus]

Truly one of those days

[empty walrus]

Hello

[hybrid depot]

True

[austere lodge]

Hi

[hybrid depot]

Anyway good luck exploring the math in here

[empty walrus]

You know the math ain't mathing when it doesn't have any numbers

[hybrid depot]

Don't wander to the end though

[empty walrus]

[hybrid depot]

Tbh

I'm afraid of numbers

[empty walrus]

I'm still exploring biology and psychology man

Math is probably the last subject i'll touch

Lmao

[hybrid depot]

Even in numerical analysis class I can't be really focus to not having any mistakes with numbers lol

[empty walrus]

True

[hybrid depot]

Had to double checked multiplying numbers a lot

[hybrid depot]

Biology? That'd be math at some point

[empty walrus]

One wrong calculation

And boom

The whole shit is wrong

[empty walrus]

Everything is math at some point

But i dun wanna touch it rn

😭

[hybrid depot]

Oh, understandable

[empty walrus]

Wanna get a headache from understanding concepts not numbers

Though maths is also about understanding abstract concepts so...

[austere olive]

math best subject so obviously everything is math 🎉

[empty walrus]

True

Anyways uhh

Yeah i'll probably start learning from addition again

Lmao

Someday

[hybrid depot]

True

[empty walrus]

This time with college level text book that i gor from somewhere

[vale widget]

Sorry that cause i think you like it

[empty walrus]

[vale widget]

I'll help you, dont worry, do you what some book again?

[empty walrus]

Nah i'd run

[tender heron]

Yeah, I mean, it's in general much easier to desensitize yourself if it is something you hear and if it is something you see happening from far away.
Which is pretty scary in some sense

[prisma lantern]

institutional preference by prof. nothing we can do about it.

[vale widget]

Rangga wanna talk to u :v @alpine totem

[alpine totem]

(」ﾟﾛﾟ)｣ᴺᴼᴼ~

[hasty current]

How do you guys study when using a textbook? Do you just read and work on the problems ahead? Or maybe you take a lot of notes?

[true wedge]

Do the problems

Go through theorems carefully

[prisma lantern]

our profs don’t have any recommended questions in syllabi, they just refer to entire sections of the book for us to do, so many of us end up doing qs that aren’t even relevant or covered in the lectures

[hasty current]

do I take notes or write down all the theorems?

[hasty current]

What if its in the context of self studying, I wanna work through a calculus textbook as quickly as possible

[prisma lantern]

you gotta remember them just like you can pull out the pythagorean theorem and soh cah toa

[hasty current]

I dont get why thats so easy to remember but then the other theorems are hard

maybe bc those other theorems are new to me?

[prisma lantern]

Get a calc textbook that’s standard for most unis, follow their lectures if available and try to find syllabi/course reading description with recommended exercises and guidande per lecture for the book. Calculus Early Transcendentals by James Stewart is a good one

[vernal token]

This depends on you

I know a few people, including me, who don't take any notes at all when reading

[hasty current]

I have that

I also have Thomas Calc Early Transcendentals 14E paperback edition

The stewart one I borrowed from the library bc I am not buying a $200 book

textbooks are ridiculously expensive even used

[prisma lantern]

Yup:
Like you should remember

IVT
EVT
8 cases of MVT (Rolle’s, Lagrange, Cauchy, Standard MVT and their integral variants)

[hasty current]

and do you retain the information easily?

[vernal token]

Yeah I think so

[hasty current]

if it works, I dont see a problem with not taking notes

its just a lot of teachers recommend writing notes down

[vernal token]

Afterwards you will solve problems anyways and will need to work with the definitions and theorems

[hasty current]

wow, I dont think Im up to that yet

I wanna start at limits bc my foundations are very weak

[vernal token]

In Germany there is no calculus, one starts with real analysis right away

And in some other european countries too

[prisma lantern]

Regarding limits, just remember to check two-sided lims and if you’re unsure check domain to see if there are any values not included for function whose limit ur checking out

[hasty current]

real analysis is calc but all proofs?

[north topaz]

yep

[vernal token]

Yeah you could say so

[hasty current]

ohh Ill def try that

[vernal token]

Spivak is more in that flavor from what I heard

[hasty current]

could you learn calculus without needing a calculator?

[north topaz]

AP calc has a ton of practice at this level

[prisma lantern]

Yea

[hasty current]

or at some point do I need to use technology

[north topaz]

yep! but technology is also very useful

[prisma lantern]

Calc on uni level is supposed to be studied w/o calculator

[hasty current]

true, but its nice to do everything by hand

[hasty current]

I see, that makes sense

[north topaz]

well then you're supposed to learn programming languages for maths

that's why you don't need a GDC

also the exam is designed so you only need a scientific calc at worst

[vernal token]

When testing out e.g. a newton iteration for something it'd be pretty tedious to do it by hand

You do want a calculator to plug something in there

[north topaz]

Euler's method, and so on

there's a lot of good applications of calculus

[prisma lantern]

we’re not allowed calculators on any math courses including the combined pure-math oriented calc1+calc2 course at my uni which is mandatory.

[hasty current]

so how should I take notes when using the textbook?

[vernal token]

pure-math oriented calc? That sounds good!

[hasty current]

I dont wanna write too much but I also want to retain all the info easily

[prisma lantern]

The profs. complicate it on purpose to weed out students at my uni

[vernal token]

we aren't allowed to use calculators either

[prisma lantern]

i dont like it, prefer standard calc as starting course

[vernal token]

Just try some things out, I guess. Try going 15 pages without notes. Then 15 pages with light ones, etc.

[north topaz]

I don't there's any harm in trying out the practice problems from that chapter first

[hasty current]

alr works for me

[north topaz]

if you realise you're missing some crucial knowledge, go back and take notes on that section

[hasty current]

Ill just read everything, reread if its unclear

and try to use that information to solve the practice problems

[prisma lantern]

Follow an already existing syllabus using the same book with lecture reference from a university, that’s the best approach.

[vernal token]

Depends on what you study, if you're a math major then surely pure math oriented is the way to go

[prisma lantern]

I happened to be unlucky since few unis use the book in my calc course + no recommended questions by professors

[prisma lantern]

im an engineering major

[vernal token]

.. then not ig

[hasty current]

Ill see what I can find

oh one more question before I go to school

can you be a math major and still be an engineer?

[north topaz]

well not usually, you'd usually have to do some kind of dual degree

[hasty current]

hmmmm I see

[north topaz]

an engineer is a protected title that requires you to take certain courses + practical experience requirements

[prisma lantern]

I guess if you take additional physics courses + mandatory engineering course for training

[hasty current]

one school I applied to had a coop physics and engineering degree

[north topaz]

you can't just take pure maths and pass the requirements

[prisma lantern]

Applied maths is more preferable in that case but you’ll still have to take additional physics courses like mechanics, electromagnetism and waves, thermodynamics, and in some cases fluid dynamics in order to be ”engineer”-compatible

[north topaz]

yeah there's specific courses only for engineers

[hasty current]

I see

so should I shift to a physics major?

[north topaz]

you might not notice this cause many unis give firstyears the same courses as maths and physics students

but it does separate later on

[prisma lantern]

yeah

[hasty current]

alr then

well I gotta go to school now

cya

[prisma lantern]

I just wish they didn’t force me w/ pure math calc course without clear guidance cuz I only had pre-calc knowledge prior

[vernal token]

@north topaz wie läuft's?

[vernal token]

this is a problem many students face generally when beginning a math major here

[north topaz]

"Läuft. Und bei dir?"

[vernal token]

in HS they aren't getting used to proofs enough

[prisma lantern]

Yup, thing is that they force all engineering students at my uni to take the same course as math majors

[north topaz]

yeah like I mean I can't really reply in German

[vernal token]

Lol

I'm doing well too, which classes are you taking this semester?

[north topaz]

all humanities

[vernal token]

🤮

[north topaz]

intro to sociology (missed out last year cause it's only offered sem 1)

intro to gender studies, gender and race, social theory and action

yep

[prisma lantern]

Im taking PolSci this semester

as an elective

[vernal token]

Did you take any math classes last semester?

[north topaz]

no lol, I took a semester off practically speaking

[vernal token]

ah

[north topaz]

the switch is real

but I'm much happier now in my new degree

[vernal token]

what's your new degree?

[north topaz]

and yes gender studies was majority female but like

[north topaz]

bachelor of arts in sociology

[vernal token]

oh

[north topaz]

also aiming for a minor in gender studies cause I've heard good things about the teaching

[vernal token]

I thought these were gen ed's you had to take

[north topaz]

I just need the right classes

the sociology sequence and the gender studies sequence, so I can now graduate in 2 years

[true wedge]

Where math wtf

[north topaz]

maths is in my personal life

not in my studies

[true wedge]

sad

[vernal token]

Your major before this was maths, right?

[north topaz]

yep

[vernal token]

And now you switched, alright

[prisma lantern]

More abt my pure math calc course, I solved a question on one of the exams using standard calc approach coming to the same answer as professor/examiner suggested was correct but because I used standard approach, I was given no points. There was no explicit mention in the question suggesting we should use complicated approach to determine boundness of integral by crafting a series comparison, I just used integral comparison to determine boundness which is valid approach and proved the same thing albeit less complicated. This is why i hate my course so bad and need to find a way to switch. In Sweden you can’t really sign up for individual courses without applying to a major, especially in math. So Im looking for any standard calc course that can be used for credits internationally. I absolutely hate my school rn.

The course has a 70% failure rate too☠️

because of these arbitrary demands☠️

[flat cloud]

@prisma lantern it might be hard af but youre not exactly missing pre requisites right?

in theory youre asked only things youve been taught

[candid compass]

What do I need to learn to understand topology?

[brave flare]

depends on what you mean by topology to be real

i suppose you mean Point-Set Topology

which really only needs a basic grasp of set theory and metric spaces

[candid compass]

What's the topology where you learn about Mobius strips and turning a sphere inside out?

[brave flare]

the sphere thing is homotopy

[candid compass]

Is that part of Point-Set Topology?

[brave flare]

not really

homotopies are discussed primarily in algebraic topologz

but that needs a good foundation of pst to be understood

[candid compass]

Oh, okay. I'll try to learn about Point-Set Topology first, which requires knowing about set theory and metric spaces.

[brave flare]

you dont actually "need" metric spaces, but i find they are more intuitive

they are basically a very nice special case of topological spaces

[candid compass]

What resources do you recommend to learn about them?

[brave flare]

there is of course the ever reliable book by John Lee "Introduction to Topological Manifolds". It starts with a basic in Point-Set Topology, after which it discusses many important things in topology, including homotopies about halfway through. It also has a short appendix on metric spaces, which lee himself says would be a prerequisite

excerpt from ToC

[brave flare]

it even has some nice figures that help with visual explanations

[candid compass]

Thank you! This is really helpful!

[brave flare]

oh i forgot, it even has a set theory appendix

so yea, this book alone has everything you "need"

[candid compass]

This book has everything.

[neon garnet]

that's a fun word.
is creating a usa island from the rest of the world a potential ultimate aim of p2025? walling in the usa, weakening allies, maintaining might, withdrawing from overseas military development discouraging deals yielding developed militaries over time, ... . trump usa sanctuary? why and when would the rest of the world prevent that?

what seems like distractions, what seems too obvious, and when does it make sense to dig deeper?

like tbfr where is this going? is it worth risking dismissing search to identify an intentional plan? what povs makes it truly make sense?

[solid snow]

No idea

Something that does somewhat explain trump is that he’s likely to be working with Russia

[true zinc]

You can ask about cramer's rule in a help channel, post the full question and a translation if possible

yes and you can post images in #chill too

[obtuse oyster]

Hi

[neon garnet]

why does working with Russia explain project 2025? why does working with Russia explain the admin's actions?

[solid snow]

sowing divide and pilfering us citizens pockets

trump has been genuinely quite fishy wrt russia for a while

[neat lintel]

Hey hey

[neon garnet]

🤷🏽‍♀️ why sow divide?

[neat lintel]

hey cleopatra

[neon garnet]

hi addmath!

[neat lintel]

hiii

[neon garnet]

i like practicing the scientific method more lately c:

[neat lintel]

i’m currently working from home and completing the poem analysis collaborative essay with my teammates over the cloud

[neon garnet]

i want to find more reasons why ideas don't work to add nuance to them

[neon garnet]

that sounds fun!!

[neat lintel]

oooh niceee

[neat lintel]

maybe but analysisng a poem is too much work and needs more creative ideas

[neon garnet]

how do you analyze a poem?

[neat lintel]

like read it, try to find the theme

um try to decipher what every words and phrases or the structure of poem is trying to tell you about

its a job that requires active creative brain and ideas

[neon garnet]

that sounds interesting! when do you feel you've found a truth about the poem?

[neat lintel]

well mostly when I suddenly realises that this word or phrase actually meant simething that makes a lot of sense to the theme

[neon garnet]

what helps you come to such words or phrases faster? history or context about the author?

something else?

[neat lintel]

yeah something like that

imagery perhaps

like if i uses one of the poem

”These are the times we live in”

by Imtiaz Dharker

there’s one stanza where they talk about scrrubbing off of mouth and eyes

now this poem is talking about the criticisms towards muslim / arabic persons during the post 9-11 period

so that stanza with those phrases talks about how the voices of those people and perspectives of them are being forcefully scrubbed out

So its trying to imply that they don’ have the power to speak up agains the dehumanising of how western people treats them and the criticism

[neon garnet]

mhm it sounds like a dehumanizing power dynamic 😞
what stance does the poem take on the prejudice towards and oppression and silencing of muslim and arabic people after 9-11?

i suppose the poem criticizes it

[neat lintel]

Well this poem is from a perspective of an muslim/ arabic

But it uses second person so that it seems like the reader is the one going through all the criticism during the trip and trying to go through the border

and with the border agent’s criticisms it talks about the dehumanising

[neon garnet]

mm. i suppose the poem aims for emotional resonance by appealing to human decency by using the second person that way.

[neat lintel]

yep

[neon garnet]

any subversion of human right, reduction to a fixed role or function, denial of autonomy e.g. forced compliance seems dehumanizing to me. what's especially dehumanizing in the poem?

[neat lintel]

now i’m trying to analyse the poem “the capital” i’m sick when they are discussing about it so now i’m trying to understand this one

[neat lintel]

I suppose its the stanza when they talk about the shape shifting of the poet’s face

as though she’s no longer human but an obejct of suspicion

[neon garnet]

hm that sounds interesting! reducing someone to only an object of suspicion sounds dehumanizing.

i feel like someone has a right to uniqueness, change, and growth

what does it mean to be treated as an object of suspicion in the poem?

[neat lintel]

it mean

[honest surge]

Hey guys

[neat lintel]

that the discrimination towards Arabic / Muslim had cause people of those races not being treated as a person of even a human being

they are just objects to be suspected by people of the western

[honest surge]

Do you guys ever came across a challenge during your studies that makes you sorta wanna back down because you don’t feel ready?

[neon garnet]

hence undermining the rest of their character, interests, personality, lives, backgrounds, uniqueness?

[neat lintel]

so this dehumanising is used to treat people as an object of suspicion

[neat lintel]

yes and hence ignoring the fact that they are also human

[honest surge]

I want to know

What are you guys talking about?

[neat lintel]

you would like to know about our poem analysis here

we are analysing the poem “These are the times we live in”

[honest surge]

Oh

[neat lintel]

By Imtiaz Dharker

[honest surge]

Not right now… math fried my brain today

[neat lintel]

thats enough math for today then

[honest surge]

Ok I’ll rest

[neat lintel]

okiee

i just receive a merit point from my english teacher for completing the porm analysis even though i’m at home

[neon garnet]

i like to practice courage. the extent of giving into feeling unready seems like inertness. i believe people are more capable than they often think. faefae li, leader of stanford's hq for human centered ai, says such challenges reasonably scare her, yet proceeds anyway. the extent of proceeding anyway, maybe getting help along the way, seems like empowerment and self belief. i prefer that. i like to practice courage that way c:

does that help, JT?

[neat lintel]

anyway gonna go eat byeee

[honest surge]

Yes it does. I took a screenshot of this to save for later. Thank you 🙏🏼

Sometimes it feels like I’m alone but this reminds me that I’m not

[neon garnet]

i like acknowledging people's humanity. in the usa, does treating someone as an object of suspicion also undermine their usa right to innocence until guilt, hence placing them below other citizens? does that sound oppressive too?

[fathom lance]

in biology, spindles connect to kinetochores right??

[neon garnet]

https://youtube.com/shorts/8du2KqMQgKs?si=8RWqaqrJWfpfoOLL this, related, was first in my yt feed

i figured id share

[honest surge]

I’ll watch

[half kayak]

I feel there must be a more scientific, evidence based approach to courage, but I’m just wondering aloud

[serene cape]

yall

so i'm trying to think about this problem for fun

as pi day is coming around i'm thinking about how archimedes came up with pi

[honest surge]

Thank you

[serene cape]

with this clever idea of inscribing regular polygons with more and more sides

and it's not too hard to figure out the area of this normally with sin and some simple trig

but i was thinking like they didn't have trig or calculators obviously in 287BC

whats the clever way of actually finding the area with very kosher strict operations?

[neon garnet]

ig my first thought seems like identity based motivation.

• i am a courageous person
• what would a courageous person do here
• practicing the answer validates the mindset
• progress confirms the identity
• describe yourself as a courageous person in reflection and convo
• reject misaligned patterns. e.g. i'm a courageous person, not an inert one.

@half kayak

where could that fail? 🤷‍♀️

[agile fiber]

we have a copy of archimedes' published work finding bounds on the value of pi. a modern presentation of that is given here: https://web.archive.org/web/20190101123108/https://itech.fgcu.edu/faculty/clindsey/mhf4404/archimedes/archimedes.html

[eager minnow]

@olive shoal

you might find that interesting as well

[neat lintel]

well it could be used to reflect it

[fresh oriole]

if somebody is suspicious they're suspicious. It's not like anyone should think "well, it might be oppressive on their rights to believe they're suspicious". They either are suspicious based on evidence, or they aren't

people can be viewed "humanely" and be suspicious at the same time

[reef forum]

mow

[neat lintel]

yeah i think so. We are talking about a poem analysis btw

just for a lil context its on dehumanising of Arabic / Muslim people from the westerners during the post 9-11 period

[fresh oriole]

ah

there was a lot of racial profiling going on in the wake of 9/11

definitely a huge reaction of racism to muslims

regrettably, of course

[upbeat heart]

[vivid halo]

You don’t need trig for this just algebra. The issue with the method is that the algebra gets insanely involved as the approximation gets better

Note that the method doesn’t say you need to find the area for a regular n gon inscribed in the circle for all n, only for large enough n so you have some freedom to choose n large enough so that the area computation is easy as possible

[neon garnet]

yes, so, "only" an object of suspicion [[1]](#serious-discussion message)

but i feel like its discrimination in this case.
discrimination as unjust or prejudicial treatment of a group of people, here on the ground of race and religion.

[half kayak]

You assume beliefs and values are the only thing that influence behavior, but behavior has many many more factors. I’m sure this identity based motivation may be helpful to many ppl, but it’s not helpful for ppl with good values but nonetheless bad behavior (such as addiction, depression, social conformation, etc.). For these people to find courage, they must seek a different way to make it, a different way to change their behavior, since identity and beliefs and values hasn’t worked (it hasn’t worked for me, that’s why I’m talking about this point)

[neat lintel]

yes discrimination certainly is unjustful here and the prejudice against the Arabic/ Muslim community is just too bad

[neon garnet]

which identity do you use?
some more ingredients of behavior change are trust capital: the reputation of self reliance you have with yourself, even formed by sticking to your word on micro goals, quick fixes, 2m instant gratification in the direction of your behavior change, and positive reinforcement, like in celebrating wins

[neon garnet]

for those cases, dr. sara wakeman says people change readily in spaces they feel safe and supported to change in. that opposes tough, rough spaces.

[half kayak]

Relying on willpower.

Also, I realize that all I’m trying to say is that some ppl like identity based, other ppl like non-identity based (like support networks, online software support, physical health, etc) and I’m the latter

[neon garnet]

i like, i'm a winner, i'm an action rich woman, i'm a resilient woman, i'm a curious woman, i'm a healthy person, i'm a growth oriented gal, i'm a baddie

[neon garnet]

why are they mutually exclusive? i feel like help encourages

[neon garnet]

yes 😞

[brazen lynx]

(Sorry to barge in) ENTJ spotted!

Literally the textbook definition

[half kayak]

I’m pretty self reliable academically except for when it comes to screen addiction periods. I think I’ve a good discipline to stick to my word on goals when I can. Not instant gratification tho, I either don’t have the energy or it’s not in my habits yet

[brazen lynx]

Teach me your methods please

[neon garnet]

you seem to know a lot about entj's!

[brazen lynx]

I really want to mature out my cognitive functions

[neat lintel]

yep

[half kayak]

This isn’t really helpful when the tough space is school, and I kinda need education

[neat lintel]

@neon garnet hey uh i’ll dm you about the poem

[brazen lynx]

Of course I do! My socionics is LIE (Basically ENTJ)

[half kayak]

Oop, ur right. They aren’t mutually exclusive

It’s about toilet etiquette tho, just a warning

[neat lintel]

haha its fine

i love analysing a poem

and if i ever came across a poem i like a lot i tend to spend some time analysing it

[half kayak]

This isn’t that kind of poem lol

#discussion message
well, i mentioned this. taste matters for me. i usually listen to PhD's, but well qualified people otherwise. i practice questions, especially those designed so that i'm right or curious but not wrong. e.g. "how does that differ from <this>?" where, when there's no difference, they're lowk the same in that convo. "why wouldn't z improve on that?"

the narrative seems shifting towards painting leaving as worse than staying, and blanket police immunity under death penalty creates... thugs? what about unethical policing?

i dont know why i let myself believe for 2s that it was for police who kill civilians 😔

[neon garnet]

such a blanket policy would enable immunity for unethical policing. how far do these implications differ from formation of extragovernmental military?

what can an organization do with that?

This user has a strong history of such behaviour

[iron venture]

Anyone ever come across a case where an instructor intentionally convolutes an answer in the back of a book? Maybe to signal a student is just copying answers verbatim?

[gusty socket]

tbh most books don't have solutions to exercises. I guess that's one way to give a wakeup call to a student.

or like

most university texts

idk about high school

but in high school texts i bet people are just using chatbots if they want to copy answers from someplace. idk if teachers are good at detecting it or what's going on in schools wrt that

[agile fiber]

math textbooks in general tend to have a writing style which is just very different from the average [high school] student

[iron venture]

Idk, is Zill ODEs high school? But when you say "most books", could you give me a example? Don't think I've reached those heights yet lol.

@gusty socket Yoooo, heart of the sunrise! Yes is the balls.

[gusty socket]

u have a favorite classical piece? can be a long one if you want.

also genre for you?

[iron venture]

Oh man... what a question. Yes, I have just the one. It's a Rachmaninoff Piano Concerto, just the piano version. Let me see if I can pull it u0p

@iron venture you also have to pick a genre so i can send a song

[iron venture]

Might as well take a classical also

[wooden falcon]

I don’t understand why there is such an expectant culture of always having solutions to exercises

[gusty socket]

do you have spotify?

[wooden falcon]

If you can’t figure out if you got it correct or not (with high probability of success), you are very lost indeed

[iron venture]

I don't personally expect them, but if they're there it's a handy quick way to check work. I'm doing this for my own betterment, so just copping the answers wouldn't do me any good.

Did you pick this because I sent you the Rachmaninoff?

[gusty socket]

no, this is just my favorite piano concerto

[iron venture]

Oh, you can tell they were from around the same time by the sound. Or at least it sounded similar enough to give him a google. Surprised you don't hear his name as much as you do the chopins and the bachs. Seems like he had enough notable works for that level of recognition.

And thanks. Wonderful piece to add to the collection. Back to the books for me.

The “self” of the child cuts itself off from other people and starts to relate only to itself so that it can maintain its identity and protect itself from external danger. The self comes to hate the world but also feels guilty because it thinks it does not deserve to be alive. The self may then attempt to destroy itself—or may split and then relate only to its false self (the self that complies emptily with the world). In psychosis the self can disintegrate into several parts or subsystems, which persecute what is left of the real self. In the end the self may no longer exist at all, but only what one patient poetically described as “the ghost of the weed garden.

[supple flame]

Only those are happy who never think or, rather, who only think about life's bare necessities, and to think about such things means not to think at all. True thinking resembles a demon who muddies the spring of life or a sickness which corrupts its roots. To think all the time, to raise questions, to doubt your own destiny, to feel the weariness of living, to be worn out to the point of exhaustion by thoughts and life, to leave behind you, as symbols of your life's drama, a trail of smoke and blood - all this means you are so unhappy that reflection and thinking appear as a curse causing a violent revulsion in you.

Anyone wanna chat?

[neat lintel]

[coarse jewel]

Things I should know before majoring maths ? Also my ultimate goal would be to be a college prof and join some research frontier

[limber thunder]

you should probably know how to prove things and how to formally express statements using the language of set theory and logic, a good starter is Hammack's book https://richardhammack.github.io/BookOfProof/

having some sort of study routine helps of course

[coarse jewel]

Nah, I didn't mean the cource contents. just other things I should be ready for

[coarse jewel]

But nvm, thanks for tip

[limber thunder]

and regarding job prospectives consider having a plan B in case academia doesn't work out, you could learn to code

[coarse jewel]

Biology ..?

[limber thunder]

I think it's sort of common to see STEM people go into data science-ish jobs for instance

[coarse jewel]

Oh, I don't quiet like that stuff, but who knows what opportunities I might get

If I get an opportunity then I might aswell join it, it depends

[limber thunder]

I think knowing how to prove things goes beyond just some course's contents, it's something you'll be doing every day if you end up researching math

[limber thunder]

that's fine, of course coding isn't the only option

there are other industry jobs, you could also just teach, etc.

[coarse jewel]

Hmm,true

[coarse jewel]

Yes indeed

Alright well, thanks for the tips! I'll keep em in mind, also, is that book called "how to prove it" good, I don't remember the author but it has a red-white cover

[limber thunder]

yes, that's another usual recommendation to start studying proofs in math

a lot of users here like that book I didn't really vibe with it for some reason

sometimes you just gotta skim a bunch of books about the same topic and then stick to the one you like better

[surreal sapphire]

imo the book is too long and gets too bogged down in set theory nonsense (especially the later parts when you compute random infinite unions/intersections)

the ideal intro proofs is aluffis notes

closely followed by my notes ofc

@neon garnet I’m delulu

Not curious

Just dumb

[sudden raven]

Hey lads. I often find myself pretty tired when studying things that are intellectually demanding (like maths or physics) for about 45 mins to an hour. I have to take lots of breaks in between study sessions

I was wondering, is this something i need to work on or get checked, or will my "stamina" increase naturally as I devote more time into maths (and other things)?

[vernal token]

I think the latter, what if you push through the tiredness? You might get used to it

[neat lintel]

You have to be consistent with your practise! Often tiredness / fatigue occurs when you aren't very accustomed to things

[vernal token]

I think I could go for as long as I want; I do feel some tiredness after a very long session though

Rarely I've done maths for about 10 hours at one piece and I couldn't really fall asleep afterwards - it felt kind of dizzy

[neat lintel]

i mean 10 hours at once... you're doing good i'd say...

[vernal token]

I surely could've gone longer, it's just a little feeling of dizziness that starts to kick in - probably if you slept well it would be longer

[neat lintel]

mind if I ask what is your "ideal" stamina

[vernal token]

What do you mean by that?

[neat lintel]

how long do you ideally want to study

(or build your stamina to)

[vernal token]

I don't know, I don't measure times, I just really love doing maths so I spend a lot of my free time (and well, it's mixed anyways if you major in it at uni - what do you consider free time and what not?)

[vernal token]

Are you a math major?

Being able to do atleast 2 hours at one piece is pretty much a must I think (that's how long an exam would go)

[sudden raven]

Damn

What were you studying for? An olympiad?

[vernal token]

Uh, IIRC I was a bit short on time and it was a certificate exam for a course called 'advanced mathematics' or the like here in Germany - but it's not necessarily tied to studying for something, I can aswell spend that much just for fun lol

Maybe not go to that extreme for that but yeah

[sudden raven]

I see. Doing maths for fun is pretty badass not gonna lie. Maybe if i get more accustomed to it ill start doing that as well

[vernal token]

Erdös regularly did 20 hours a day

But he's generally not a good example lol

i dont think doing anything for more than 5 hours straight is healthy at all...

[neat lintel]

didnt you just say you go for 10 hours??

[vernal token]

Yes I did, I once did 10 hours

But I'm saying being able to do 2 hours is enough

[vernal token]

I wouldn't want to consistently do 10 hours straight every day - with breaks it's quite doable

[neon garnet]

it sounds like you're listening. would a curious person listen?
ask a question?

i dont use smart, dumb, ... . a short person with a ladder reaches taller than a tall person without one, to me. i like to stand on the shoulders of giants. that tangibly means quoting from the best, or letting them speak through me, for me. anyone can let qualified voices speak through them, imo.

you ultimately enjoy or endure the consequences of your reality. studies show the extent of curiosity and grit -- growth oriented mindsets -- beats that of fixed alternatives. it's your life you're resonsible for, and it's your choice. are you delulu or [a curious gentleman](#serious-discussion message)?

[vivid halo]

lol no he did not

[gusty socket]

but I did

[vivid halo]

You can certainly do 20 hours of work in a day if you’re on amphetamines like he was but then you crash and sleep most of the next day

Better to just work 10 hours a day more consistently

[supple flame]

20+0/2 = 10 hours of work

[vernal token]

Yeah obviously it's most likely not possible do to this naturally over an extended period; I did say he used caffeine pills and amphetamines he was prescribed because of his depression

[vivid halo]

Yeah I’m just saying that “regularly” does not mean every day here

[neon garnet]

i hope you practice the latter

So i was playing around with some rational distributions after being inspired by the mathologer Fibonacci sequence making all the rational numbers. I was looking at layers of Stern-Brocot Tree and then noticing that they are clumped together and I like them to be seperated more.

I have a question

why, do u guys think that, there are people who good at math and bad at it

[north topaz]

good and bad are relative terms

fundamentally it's about effort, time, practice, and interest

[hexed pond]

For example high scores

[north topaz]

are you talking about high school maths?

[hexed pond]

no, undergraduate

gpa

[north topaz]

well a typical maths course has all sorts of pure maths, applied maths, and stats usually

also it really depends on country then, in terms of how many electives you can take

[north topaz]

GPA doesn't really mean shit

[hexed pond]

why not

it is a form to assess performance right?

[north topaz]

the trend of college students taking easy courses as GPA boosters is as old as time

[hexed pond]

oh..

my major dont have electives

we just take the courses that everyone take

but one of this course is hard as hell

calculus

[north topaz]

single-variable calculus?

[sonic sentinel]

wtf i found out an acquaintance from school has been doing side quest shit for idk how long and has a >10k subscriber channel and features regularly on someone's >500k sub channel (both channels roblox)

[hexed pond]

idk what that means

[sonic sentinel]

completely fucking bizzare
he invites me to a server and im like do you guys know [friend] and the server is like r u stupid everyone knows [friend].

i check out the youtube channel associated with that server i go to a random video i hear his voice midway

[hexed pond]

Calculus : early transcendentals

that is our textbook

[hexed pond]

dude u got a cool acquaintance

[north topaz]

yep so that

[sonic sentinel]

im not sure how to feel about this. i think i feel a little jealous and also a little hopeful that people in this kinda shit school have actually managed to do stuff like this

[north topaz]

so you must be first-year right

[hexed pond]

indeed

[north topaz]

hopefully you're adjusting to the more independent style of learning at uni

it's really not like high school at all

[hexed pond]

yes

[north topaz]

you have to actively participate and ask for help; don't leave things too late

consultation hours and tutorials are golden

[hexed pond]

thank you

[north topaz]

because there's nothing impossible about single-variable calculus

yes, even if your calculus has proofs (so it would be called analysis)

[hexed pond]

okay!

[north topaz]

it's just a matter about organising your learning so that you can ask your prof or TAs all your doubts about the week's content when you see them

or write them all into 1 email

[sonic sentinel]

this is like in tv when they leave a comedic relief character out for most of an episode and then they come back to see him and he's now ruler of the world

[north topaz]

cause after one of your questions is resolved, you'll find that maybe the others are also answered this way

[hexed pond]

Thank you sincerely for your advices

[north topaz]

same with lectures, there's really no such thing as a 'dumb' question

alright I won't lecture you anymore

[hexed pond]

I really needed to hear that

haha

[north topaz]

just wanted to let you know that there is a way out of this

[hexed pond]

bro maybe you should do the same

haha

if you're a little jealous then you can put in some effort as well, that would ease the anxiety

[sonic sentinel]

no not really

i don't do video games anymore

barely

there is some other stuff i could do though

[hexed pond]

u can be a math youtuber

hey everyone, i need some help with a math problem. i'm trying to see if there exist specific values of g, m, and c that satisfy this equation for all n:

(n / g)^(g(mn + c)) + g^(n+1) - 1 = n!

g, m, and c are just constants, and they aren't complex or anything. they can be positive or negative, but they have to be chosen very specifically. i believe such values exist, but i need a proper proof, not just checking values randomly. can anyone help prove or disprove that such g, m, and c can always be found?
g^(n+1) - 1 here minus 1 is not in the exponent btw

[brittle socket]

Can't you just slap taylor series to see whether your claim is true

[vocal zenith]

Why are there more letters than numbers

[deep mango]

you can make the letters any numbers you want and it works

[north topaz]

there's so much more of maths that you haven't seen yet

[warm pecan]

divide both sides by (n/e)^n; by stirling's approximation, the right side is O(sqrt(n)), so as n->inf, the left side must go to infinity, but not at an exponential rate
looking at the term (g^(n+1)-1)/((n/e)^n), n/e>g for sufficiently large n, so this term goes to 0 as n->inf
thus we are left with only the term (n/g)^(g(mn+c)) / (n/e)^n; now if g*m != 1, it should be trivial that the term either goes to zero or increases far too quickly, as you'd be left with a factor of n^(gm-1)n. Hence gm = 1.
now the term is (n/g)^(n+gc) / (n/e)^n; if g != e, we will be left with a factor of (e/g)^n, which once again means the term decreases or increases too fast to be O(sqrt(n)). Hence g = e.
but now, the term is (n/e)^(n+ce) / (n/e)^n = (n/e)^ce, and for it to have O(sqrt(n)) growth, ce = 1/2; so for the expression to hold at all, g = e, m = 1/e and c = 1/(2e), yet with those constants the expression does not even hold for n = 1.

That's the rough idea of the proof, at least

[solid snow]

@wild lantern since we were discussing different LA books some other day, something i will say is that FIS has much better notation for the matrix representation of a linear transformation

than axler

[fresh comet]

what’s Axler’s notation?

(I am too lazy to pull up the PDF)

[solid snow]

well we he has linear transformation T : V -> W with bases v1,..,vn and w1,..,wm respectively then he does M(T, (v1,...,vn), (w1,...,wm))

@fresh comet

[fresh comet]

ugly

[solid snow]

compared to FIS where they denote a basis of V with $\beta$ and a basis for W with $\gamma$ and then the matrix representation of $T : V \to W$ is $$ (T)_{\beta}^{\gamma}$$

ugh

[fathom swallow]

josemom2

[solid snow]

its brackets instead of parenthesis but icba with latex atm

I think Tao uses it this way too. It's so much more compact and lets you keep track of compositions for some stuff since you have $$(ST){\alpha}^{\gamma} = (S){\beta}^{\gamma}(T)_{\alpha}^{\beta}$$ for T from U to V, S from V to W and bases alpha beta gamma respectively

how do you go about reading math books? do you try to remember each theorem? do you skip things if they are too hard? I went through 12 pages of book and it took me week (the entire book is 360 pages)

[river moon]

no and yes to these two

it shouldn't take you a week to read 12 pages, but it could take a week to fully understand these 12 pages

[brave flare]

dont remember theorems

understand them

[sudden ibex]

I was trying to understand it the entire week

I did the exercises too

[river moon]

how much time have you dedicated daily to that?

[sudden ibex]

but my solutions was a little wrong

1 hour

[river moon]

well that's not enough, typically you spend 1 hour trying to recall what you were doing last time

it's better to spend 3-4 hours, maybe not daily if you don't have time for that, but regularly

[sudden ibex]

I will try to set some goals and do as you say

[narrow carbon]

hi TE.
Do you remember, once upon a time you gave me this advice. iirc i asked how can i put pressure on myself during selfstudy and you suggested me to set a timeline like i will study 3-4 hours per day. You know what it was awesome, maybe it didn't put pressure on me but studying 3-4 hours for a few weeks results so nice (i did like first 5 chapters of FIS -- linear algebra in 5-6 weeks, bunch of chapters of analysis and now doing Algebra)

[hollow gale]

I often go back to one several times. but typically i first read through a book at a brisk pace over only a few days to get an idea of where things are headed and what sort of intuition is needed. just trying to understand the proofs. then I start over and start doing the easier exercises. then I start over again and start doing harder exercises

sometimes a couple of pages can take several days to digest

hey guys i need help regarding applications to uni

i did ask help in the discussion but no one seems to know much about it

[true wedge]

what help?

[neat lintel]

yeah so im planning to apply to ntu singapore

and need to know about my acceptance part

like every other country, my country has a high school leaving examination similar to 'a levels' called cbse boards. so in that we are assigned to opt for 5 subjects so mine were (physics, chemistry, math, english and computer science) i completed this examination and i scored 97% in english and computer science but my physics,chemistry and math were done terrible (i scored 65% in these as i didnt prepare well). so cbse boards have a thing called cbse improvement exams in which if a person wants to improve their grades in any number of subjects, they can reappear the next year meaning write the exams again with the next batch (if they pass) so im planning to go for improvement exams on physics, chemistry and math to increase my overall % to 95%+. will the top universities like ntu/nus accept these improvement grades? (btw when submitting application form i have to submit both as i'll only be reappearing for phy,chem and math so my english and cs would be calculated from the previous one). please guide me through this.

[true wedge]

hopefully someone else will answer. i dont know much about this

Best of luck in any case

[surreal sapphire]

you have to ask the universities

this is very specific, its extremely unlikely a random person on the internet will know this

[neat lintel]

you mean approach the university assistance counter or something?

[neat lintel]

alright yes thank you

[surreal sapphire]

yes

[neat lintel]

should i like fill up a form or any procedure for it or just simply ask them?

[surreal sapphire]

i would just try to find an email and ask the question

[neat lintel]

alright cool bro

[neat lintel]

Aw chat just wanted to ask.
I skipped like 3 grades from 5th to 8th, so, how much time would it take to gain the knowledge up?
Would also be good if you used to have experience with Russian school program, so you can give most relevant answer.

[neat lintel]

a month if you're consistent, you can go to some bridgecourse or attend a few lectures on the basics and you'll be thorough with all the concepts not sure about russian school programs.

no but like srsly

everyone says "oh this is just an O(n)-bundle"

i realized that doing math is just learning enough math to make ur problem a corarlly of some theorem u learnt and it seems lie groups make this happen alot

things as simple as proving something is a manifold can be done by just realizing it as some action bla bla

Anyone good with simulink here? I am stucked on a tutorial

[rocky vault]

my keyboard is also gay hexagons @gentle birch

[gentle birch]

💀

anyways did u just start playing brawl

[rocky vault]

yea

[gentle birch]

have fun

it's a good game

[rocky vault]

this kid plays it every day in study hall and I was bored

[gentle birch]

did u get surge

[rocky vault]

nah I don't think so

[gentle birch]

oh he's free rn

[rocky vault]

Idrc about the game enough to care abt free stuff

but cool

[gentle birch]

alright

[little light]

Surge?

I mean his skin was kinda fire

[rocky vault]

HAHHAHA

[brave flare]

damn he called you a bitch

and a

a moran

[rocky vault]

"dumb sick moran" was also the last message he sent in physcord before getting banned

[fresh comet]

physcord turned it into a sticker

[little light]

That’s crazy

[brave flare]

"old reliable"

[rocky vault]

HAHAHA

that's hillarious

he also got mad bc I didn't answer √3+i/√3-i in about 15 seconds

because I was working it out on the computer instead of just looking it up

[gentle birch]

ask him where he's from

[rocky vault]

I got it wrong but oh well

not like he's gonna know

while I'm waiting could someone actually tell me what I did wrong here
√(3)+i/√(3)-i = (√(3)+i)(√(3)+i)/(√(3)-i)(√(3)+i)
expand the denominator, 3+√3i-√3i-i² = 3+1
expand the numerator the same way, it's 2+2√3
the answer is (2+2√3)/4

that's what I got but according to wolfram the actual answer is (1/2)+(√(3)i/2)

[brave flare]

wait lets tex it real quick

ah

just the 3s in the roots

[rocky vault]

hm?

[rocky vault]

oh I forgot the is in the 2√3

[brave flare]

yea i was wondering if just the 3s or the is aswell are in the roots

[rocky vault]

yeah I had no idea

[gentle birch]

this is a pi ok

they took too long and I removed friend

[vast wraith]

no its not

[gentle birch]

Listen, you're not one to comment about handwriting

I mean @vast wraith I like your handwriting

It's very aesthetic

[agile fiber]

your pi looks closer to a lambda

it should be much more square

[rocky vault]

LMAO THEY HAVE AN ALT

[vast wraith]

my pis are impeccable

can anyone help me?

i mean yeah

[visual thorn]

I think I found a more succinct way to say what I was saying before about how the real numbers are very hand-wavy and jerry-rigged. No one can disagree with this: it's impossible to make a unique statement about every real number. If you had the set of equivalence classes of the integers under the relation a ~ b if a - b = n (aka modular arithmetic with modulus n), then that's a finite set, and you can study every element of the set and see if there's something interesting about it or not. You can't do that with every integer and you certainly can't do it for every real number. That's my issue. I don't think people shouldn't use real numbers, I just think we should admit that any time we make a statement about a subset of real numbers, the statement can only be crude. You can't look at each one individually to see what interesting properties it has.

[split compass]

What are some reputed math journals

[leaden torrent]

Too many to list

If you wanna read math papers just check the arxiv

They're preprints so they're not peer reviewed but most of them are legitimate

Just avoid the math.GM section

[split compass]

I am below 18 and want to publish where should I

[surreal sapphire]

i dont think there are age limits, generally the works you are citing should give an idea of what kind of journal to aim for

[brave flare]

buddy, the only place that is going to accept that which you have shared on here thus far is vixra

[split compass]

What about probability,algebra and number theory

[surreal sapphire]

what

[leaden torrent]

with respect, if you havent read any serious mathematics papers, you are not ready to write a mathematics paper

[split compass]

But still for future what journal will accept all three topic

[leaden torrent]

thats a very broad swath of topics, so you wont find many journals accepting everything in all three - usually journals are a lot more specific

the main exception are the incredibly highly-reputable ones that publish the best papers in the world, like Princeton's Annals of Mathematics or the Journal of the AMS

but i would not think about publishing in those journals until you have already published decades worth of mathematics

it just doesnt happen, even once-in-a-generation talents like Peter Scholze had many publications before getting in one of those

again, the best place to find a journal to publish in is to look at existing work in the field and see what journal that was published in

i only really published in a couple of journals during my PhD, and afaik that's the typical experience

there's a ton of journals out there but most are very specialized

[split compass]

OK will make sure to read mathematics papers

[leaden torrent]

you're going to have to regardless if you want to get published, since you'll need to cite existing work and place your contribution in context

[split compass]

OK got it

[sharp mulch]

Annals

[supple flame]

not to be confused with annals

[proper plume]

Yeah yeah boy annals.

[modest sky]

i get confused and nervous everytime i look at questions bruh

[static loom]

I wish I could give helpful advice for that

[jolly vale]

Hello

@static loom do you know how to give talks here

[static loom]

I don't

[upbeat heart]

[unborn meteor]

try dming @polar panther

[lost fjord]

uhhh for your proof of collatz conjecture, the best place to publish would be on the joe rogan podcast

[jolly vale]

Thanks a lot

[eager ledge]

People have done it on Youtube as well (do not try and look up “how I solved Collatz and Terence Tao couldn’t” – or something in this vein). I do not advise MSE because people tend to downvote anything that seems to inch towards a well-known major problem.

[split compass]

I know I have written it badly .but once you get what I did it's not so bad.just give it a try.

[uneven steppe]

A crank in the making

[surreal sapphire]

once you get what you wrote, you will realize it is bad
really, its incredibly insulting to assume you can solve a problem that top tier mathematicians have attempted for years in a few pages with no background in mathematics at all

[split compass]

No one have proved it because every one is trying to prove it for infinite range. Infinite is not valid entry in the function. What I did instead was to prove it for all finite range. Show me someone's work trying that .

[split compass]

Find mistake in proof before claiming it's wrong

[surreal sapphire]

i dont know what that is supposed to mean

[split compass]

What that mean is that you can't put infinity in function of conjecture

[surreal sapphire]

multiple of your statements do not even make sense (you were told this yesterday regarding your issues with probabilities), it is unclear how any of that implies the conjecture

[split compass]

I will explain entire thing just don't quit in between

[surreal sapphire]

no

your unwillingness (or inability) to interact with criticism just leads me to tell you to stop talking about this from now on.

good luck with your publication

[split compass]

Ok

[brittle socket]

Classic crank moment

[idle burrow]

hai

[viscid abyss]

@split compass In all likelihood collatz is undecidable. Conway showed that generalized collatz was undecidable

In the 1970s

[split compass]

What does that mean

[viscid abyss]

Not every statement can be resolved to true or false

[split compass]

It's not applicable for infinite but for every positive integer It's true

[viscid abyss]

Lol how's that relevant to what I said

Prove the following is either true or false: "this statement is false"

There are plenty of conjectures which have proved undecidable

For examples Hilberts 10th problem

"Given a Diophantine equation with any number of unknown quantities and with rational integral numerical coefficients: To devise a process according to which it can be determined in a finite number of operations whether the equation is solvable in rational integers."
https://en.m.wikipedia.org/wiki/Hilbert's_tenth_problem#:~:text=Hilbert's problem is not concerned,problem is an undecidable problem.

[split compass]

I am proving its true only for the way we do multiplication or division or we consider number to appear(digit to repeat after ten digit) I am not proving it absolutely true

[viscid abyss]

[split compass]

What do you mean

[fresh ermine]

[queen bobcat]

If you're not proving that it is "absolutely true", then what are you proving? :/

If this mysterious function you're talking about is the Collatz function, for example taking 2 --> 1, then it's not clear why you'd be considering C(infinity), if that's what you're saying.

On top of the mathematics being unclear, the language barrier only worsens this.

You should focus on learning real mathematics instead of grasping at intractable problems..

[queen bobcat]

If you think this is true, then you should write an actual paper which organizes your information and runs through a proof. Professional mathematics isn't done by showing poorly cropped images of lists of statements without proof.

[uneven steppe]

The world needs some cranks

It keeps things interesting

[old oak]

I just wish they had broader interests, most of them seem to pick Collatz, Riemann or Cantor

With so much mathematics out there, one would expect a greater variety of crank interests

[uneven steppe]

I mean they all have some problem with infinity so it starts there

[brave hollow]

I will prove Bunyakovsky Conjecture

[true zinc]

Also the issues they see are "simple" enough to be comprehensible without a full degree in mathematics

[old oak]

Sure, but where are the geometry cranks for instance? I want to see someone squaring the circle in 2025, dammit

[true zinc]

I've seen a few in here sometimes

[deep mango]

oh my lord someone just spilled a bunch of stuff from their sandwich on the floor. what is wrong with these people

[old oak]

Some people are cranks, meanwhile ryc is just cranky

[deep mango]

YESSS GET OFF THE TRAIN YOU LOSERS WITHOUT HEADPHONES

[agile fiber]

geometry cranks seem to have declined with the general de-emphasis on geometry in the hs curriculum

[uneven steppe]

There’s a really famous geometre crank, NJ wildberger or something? He actually has tons of “real” math research too

[deep mango]

nooooo whyyyy they were just putting their doritos away

oh i switched to discussion 2

[agile fiber]

it used to be that cranks would be obsessed with whatever they learned in high school, which is why there were so many compass-and-straightedge cranks. now cranks are obsessed with whatever famous conjecture they learned about in a pop math youtube video

[true zinc]

Popmath and popsci were a mistake

[vague eagle]
