then asked the same question in discussion

[limber thunder]

[narrow carbon]

She usually asks the same question for atmost 5 to 6 times

Recently i came to know this

[pulsar pagoda]

well she also said that her parents noticed she had autism and their both pediatricians, but somehow she doesnt get diagnosed with a psychaitrist?

like

I have autism

and that sounds weird to me

idk

or... an astrophysicist

[flat harbor]

astrophysics is like

cool

but the least cool out of the physics collective

[sharp mulch]

That’s so false bloe

[flat harbor]

ok fine

condensed matter ppl are lamer

imagine being in semiconductors but poor

[sharp mulch]

Condensed matter is the least cool

And personally I think that astro >>> AMO

[flat harbor]

its just that

ppl tend to conflate astrophys with aerospace

[sharp mulch]

Who does

[flat harbor]

a lot of ppl who ive seen that say they wanna do astrophysics

theyre like "i think rockets are cool like. isnt space cool" and they show u pictures taken by space telescopes

and wel... ive got bad news...

aerospace is unironically an S tier field id go if they took me

u become an astrophysicist and just sit in a room in front of 10 yr old software

[thick yacht]

Imagine higher category theory being of practical use.

[flat harbor]

i actually cant

hilarious

[tawny blade]

What's higher catagory theory; Is this homotopy type theory?

I can and do use this.

very cool subject, trying to figure out how to describe it in English is not easy though.

Least so far as I understand the subject I do.

[thick yacht]

It's a multilevel category in which Homsets form their own multilevel (-1) categories.

-1 as in a different topology? I'm not an expert in this at all, but am very intuitive as to how the subject works, I'm trying to learn the notation and language used.

in a mathematical context.

[flat harbor]

preuni role
roflcopter

the only category in physics ive seen that i can Grasp is homotopies of master equation solutions

[tawny blade]

I'd argue that this is clearly the space that thought operates in.

I'm familar with eastern philosophy, and this is why the subject intrigues me deeply, very strong parallels.

[flat harbor]

aight going back to not posting on this server lmao

[tawny blade]

vis check out the computer generated images of thought now generated from brain scans.

[thick yacht]

As in the homsets of n-categories are (n-1)-categories.

[tawny blade]

yes, I'm not familar with the langauge, as mentioned. Comming from a different field.

... still reading 🙂

but do have strong hunch that there are vast applications.

in the domain of conciousness, and understanding how it works.

Great web site, thank you for the link, bookmarked.

[blazing pawn]

Devastating that things have reached this point but unfortunately it is in symplectic topology now

[tawny blade]

Thankyou reading about them now, very simple, its the nomenclature that is confusing, as if english is not really cut out for the subject.

Nested categories, this is really the same thing as inheritance in programming, right: so (n-1)-categories is like calling .self or .super?

Or am I being presumptuous?

some of them (the commutative diagrams at least) were also made using tikz

[hoary moss]

anyone know how the distinction between ball and sphere is like in other languages?

[surreal sapphire]

wdym exactly?

do you just want the names for the mathematical objects in different languages?

[north topaz]

https://en.wiktionary.org/wiki/ball

https://en.wiktionary.org/wiki/sphere

French is different

German has the same word

Bulgarian has 2 very similar words

oh Japanese also has the same word

as does Finnish, pallo

[vocal vessel]

Ball and sphere aren't the same in Japanese.

玉　球

you cant look at those things on wiktionary

go to the wikipedia page of the mathematics term and then switch language

ball doesnt have a german article, but its Ball

[shell fern]

how do I write a math research paper?

I have to write one for class but the teacher didn't really make it clear how we should like make the topic

like I know solving an unsolved problem or discovering a proof in mathematics is like the basis of a bunch of papers but im in high school so that's too hard for me

so how would I make a research paper with some original content

[wild lantern]

You would probably write something expository about a topic that interests you.

[shell fern]

how is that original though

bc its just like rerwiting information that I found elsewhere

[wild lantern]

You're not going to do original research as a high schooler on your own most likely.

[shell fern]

but I feel like it should be directed

[wild lantern]

Directed in what sense?

[shell fern]

and like do somethign at least resembling original content

[shell fern]

well we have to submit it to a math fair

[wild lantern]

I think the expectation that you're going to do something original or novel is unrealistic.

[shell fern]

yeah, but I feel like it should have a purpose

[wild lantern]

It is not uncommon to finish a math undergrad degree without having done any research

[shell fern]

like not just regurgitating information about the topic

[wild lantern]

The purpose here would be for you to learn math that is new to you and to communicate that math to other people.

[shell fern]

my teacher has a section on the rubric that says originality and I lost points on it last year and the year before that

[ionic star]

it's necessarily original

it's like news can;t be unbiased

because they have to skip some news entirely

[wild lantern]

Your teacher has unrealistic expectations if they expect you to do original research.

[ionic star]

the things you said and the parts you skipped are orignal to you

[wild lantern]

Seems a lot more like you need to ask them what they mean by "originality" here.

[shell fern]

do you have an idea how I could do at least something original

[ionic star]

same as unique

[wild lantern]

I think the expectation that thought to do something "original" is either vague at best or stupid at worst.

[shell fern]

ok I guess i'll ask my teacher

should I have like a thesis then? cause for historal papers

historical

like what do I start it with

[wild lantern]

I do not know what the requirements of your paper are or how they want you to structure it.

Like, imo

[shell fern]

what do they usually start with

[wild lantern]

The sanest overarching goal would be to pick an area of math you think is cool and try and explain it in a way that a laymen can understand. And this would probably guide how you'd write this kind of paper.

[ionic star]

i don't think it's vague

or i guess yeah i think there's no expectation

[sand schooner]

Can anyone help me solve trigonometry

[ionic star]

so if there is, it's stupid and unexpected

[wild lantern]

So like you'd probably start with a problem that the math you're talking about intends to solve. Explain it, the background. Maybe some history. Then maybe you explain some of the formal definitions and ideas.

[shell fern]

honestly yeah now that I think of it

[wild lantern]

Then possibly try and explain some results using those tools

[shell fern]

in alg 1 when I asked my teacher how to make it original he was just like "yeah do something new"

[wild lantern]

Maybe end on like, some future things people do with the math you're talking about.

Something like that I guess.

[wild lantern]

Ask them to clarify what that means.

"Something new", according to who? You can't read this dudes mind.

As a hs student there's only so much that should be expected of you mathematically too.

[ionic star]

if you use the words that people already use there's some originality in it already (because you skipped some parts you consider unimportant and that choice is not predefined)

if you start naming things, that's even more original

[wild lantern]

I don't think guessing at what counts as original here is so productive.

[ionic star]

i do

[wild lantern]

The person grading them clearly has something in mind and has marked them down in the past for not doing it.

[ionic star]

so i'm guessing what they have in mind

[wild lantern]

They should just ask this person what they want.

Yeah, that's a bad strategy compared to just ... asking the person doing the grading what they want.

[ionic star]

they won't tell

[wild lantern]

They will if they don't suck.

[ionic star]

the teacher wants you to guess the password, they won't give it up

[wild lantern]

That's a horrible way to grade in general.

Grading and evaluation just shouldn't be some silly guessing game.

[shell fern]

wait how would I make a paper that stands out then

[wild lantern]

Rubrics exist for a reason.

[shell fern]

without like making anything new

[wild lantern]

"Standing out" is subjective.

[ionic star]

if guessing what the teacher has in mind without asking is unproductive

then everything is unproductive

[wild lantern]

That's a silly conclusion to make.

[shell fern]

it's for a math fiar

for like my county

a bunch of students do it

[ionic star]

you;re not implying that "horrible" means it doesn't happen

means you're implying that playing stupid games is unproductive

[wild lantern]

Cool, but that doesn't mean "lol imma guess" is the right choice if you don't know the standard you're being held to.

[ionic star]

i'm pretty sure it follows that everything is unproductive

[wild lantern]

I'm pretty sure you're jumping to silly conclusions

Irl if you had some work evaluation to do and you were unsure of what standards you had to meet you would ask.

Professors and teachers put effort and time into defining standards and rubrics as well.

If it's unclear what you need to do or what requirements you need to meet, asking for clarification is basically always preferable to just guessing.

Believe it or not, you aren't a mindreader and any expectations that you are is just incredibly dumb.

[ionic star]

yeah you should ask, i said they won't tell

[wild lantern]

It really depends on the professor. Like, a good one will at least try to help.

[ionic star]

and you dismised it cimpletely

[wild lantern]

Yeah because it's a silly conclusion to jump to.

[ionic star]

which one

[wild lantern]

A good teacher wants you to do well and will try to help you however they can if you come to them with genuine questions like this.

[ionic star]

it's silly to start guessing now before you asked?

why?

[wild lantern]

The thing you are saying I dismissed here.

I am dismissing that, because it is silly.

You don't know this professor.

[ionic star]

there's like 20% chance they won't tell, why not start guessing

[wild lantern]

Yes it is in fact silly to make conclusions definitively about people you don't know and instead resort to just guessing and trying to read peoples minds.

[wild lantern]

Why not ask first instead?

[ionic star]

there's time before that happens

you don't know pogrx maybe

[wild lantern]

Man, you really want to be right about this.

[ionic star]

they can;t find a more productive way to spend time

[wild lantern]

Not gonna lie your point here is incredibly stupid.

Like, no, don't just guess or try to read some randos mind. Just ask if something is unclear.

[ionic star]

why

you have time to guess, in case they don't tell
if you have nothing better to do, start guessing, start asking what they could mean on discord

how is it stupid

[wild lantern]

Because you can't read a persons mind and getting clarification on the actual standards you are being held to is more likely to lead to you meeting those standards than making up your own set of standards in your head that could be totally wong.

[ionic star]

just don't apply them if they tell you lmao

[wild lantern]

Why not just ask instead?

[ionic star]

maybe it's nighttime

[wild lantern]

Maybe jumping to conclusions randomly is silly.

You can not know stuff at night. Nobody will come arrest you for it I promise.

[ionic star]

maybe i'm silly so on any topic you would only admit i'm right when you misunderstand me?

[wild lantern]

I feel like I understand you pretty well. I just think your point is bad.

[ionic star]

you didn't admit i'm right, so it stands

if you understand correctly, you won't admit i'm right

[wild lantern]

Why would I admit you're right? Am I not being blunt enough? I think your point is bad and that you are wrong.

[ionic star]

if we're assuming i'm silly you wouldn't admit i'm right unless you misunderstood what i'm saying

[wild lantern]

Peak silly behavior

Good luck

[ionic star]

you as well

[pulsar pagoda]

doot what courses are u taking next semester?

[ember lance]

Let's say it takes me 10 minutes to get to the store on a bicycle on a 26 to 33 celsius day. Would raw chicken, frozen food, etc get spoiled in my backpack on the trip back from the store?

[solid snow]

get a cooler

[limber thunder]

yeah that would be ideal else you risk breaking the cold chain

[ionic star]

they wouldn't even thaw

they would get refrozen, which is supposedly not cgreat

but spoiled is not that

[daring parrot]

can i get a decent paying job by completing online certifications these days or no
with just a ged, no hs diploma

like one path a friend did was nurse vocational school and became licensed vocational nurse in 1 year, any other ideas?

[ionic star]

@ember lance10 minutes is less than what usually happens

[neat lintel]

Work in construction

Or electrician

Or hvac

Pretty easy to get into

[ionic star]

like if you go to the other part of the city in a car, that's gotta be 15 minutes

[neat lintel]

Just need to study a lot

[ember lance]

Oh, I keep track of time in most things I do. 10 minutes is average for that trip to the store.

[edgy adder]

can anyone suggest good reference books for mathematics for data science.

[ember lance]

I wish Fujimoto would stop writing CSM and just focused on delivering a bunch of one shots like Goodbye Eri and Look Back.

[verbal karma]

Depends on what level do you want to look into and what kind of "Data Science" you are aiming for. If importing sklearn is consider advanced or complex, then you can start from some basic calculus and basic statistics (typical freshman textbook would do). There usually no one-for-all textbook or book on math for Data Science because expectation in the field varies. You can just use only basic math for day to day analysis, or you could use the whole optimal transport field to tackle on the problem in Data Science.

At the very least, you probably need: Multivariate Calculus, Linear Algebra, Statistics, Probability (probably not math student kind of probability). These are widely just freshman level class which you can use typical freshman level textbooks for it.
These are optional topics but is really useful: Real analysis, Complex analysis, Stochastic Processes (or even, stochastic calculus), Optimal Transport, PDE (if you are into the computer vision), Optimization, and other that I can't think of on top of my head.

Advanced Statistics and Probability book:

• "Statistical Inference" (Casella and Berger, 2024) is a classical introductory book to mathematical statistics. Mind you that problems in there are really challenging but also rewarding.
• "Mathematical Statistics" (Shao, 2010) is also classic book on mathematical statistics. Usually suggested after Casella.
• "Theory of Statistics" (Schervish, 1995) another well-known classical one. Good read if you are into more Bayesian statistics.
• "Bayesian Data Analysis" (Gelman et al., 2016) really good book if you are into the Bayesian statistics. However, the prerequisite and introductory part is a bit lacking. You might need to have some background to tackle this book comfortably.
• "Probability: Theory and Examples" (Durrett, 2019) Classic and good book on probability period.

If you are more advanced and into the modeling

• "An Introduction to Statistical Learning" (James et al., 2023) which should cover the basic of statistical learning. Essentially machine learning but from statistics perspective. Available free online from the author.
• "Pattern Recognition and Machine Learning" (Bishop, 2006) very good in-detail book on machine learning. Very much Bayesian perspective of ML. Also very classical text on this. I think this also available for free online.
• "The Elements of Statistical Learning" (Hastie, Tibshirani, and Friedman, 2009) essentially extension of "An Introduction to Statistical Learning". Very through
• "Modern Multivariate Statistical Techniques" (Izenman, 2006) Good book for anything multivariate (including regression, PCA, a bit of manifold learning, etc.)

For some theoretical stuff

• "Foundations of Machine Learning " (Mohri, Rostamizadeh, and Talwalkar, 2018) will touch upon the machine learning from ground up. Good for someone starts to learn machine learning from theoretical perspective.
• "A Probabilistic Theory of Pattern Recognition" (Devroye, Györfi, and Lugosi, 2013) one of the underrated book on this field. Quite old but not that it is not useful.
• anything with Vapnik name is usually good source. Quite a bit hard to wrap your head around if you are self-studying but for sure is a good read and can give you nice intuition. For example, data augmentation and Lie operator.
• research paper from respectable conferences or journals like Neurips, ICML, ICLR, JMLR, etc.

For specific kind of model like Deep Learning or some field like Reinforcement Learning, I can suggest you the book for those fields separately. But these are generally what people use to get their foundation ready and to referencing stuff (not exhaustive).

i cant solve the integral of e^x^2 xd

ill still try to solve

[true zinc]

e^x^2 has no solution in elementary functions

[verbal karma]

and if it is improper over the real line, that integral diverge

[true zinc]

a quick toss into wolfram gives you this

[verbal karma]

its counterpart with negative sign e^(-x^2), however, will converge

Yeah so even computing the gaussian integral ( the variant with a - sign) is a total pain in the arse unless you know a few special tricks

erfi is pretty well understood

we can approximate it to arbitrary precision

[white temple]

i have a sweet spot for non-elementary functions

[true zinc]

same

[jovial ember]

This is true for like, all shapes. When you take a “surface area” (this can be for even more dimensions than 3) it’s the derivative of the “volume”. Or what you said, that’s the inverse statement cuz of FTC

But you need to be careful about how you do it, because when you do a square which has side length l, the area is l^2 whose derivative is 2l but the perimeter is 4l

But that’s because you needed to use “radius” which is l/2, in that case the area is 4r^2 and the derivative is 8r = 4l

[flat cloud]

I see I see

the integral of pi*r^2 would be the volume of a cone?

Does your uni have a mental health clinic?

[flint thunder]

Yes, I suppose I could go there. I'm trying not to involve the university directly

[ember lance]

Why not?

[flint thunder]

I don't want to get in trouble, or have anything like this on my "record" or whatever

[amber fog]

If they’re offering things like counseling services, they should be confidential (assuming you’re in the US)

You should ask about confidentiality for sure

[ember lance]

I think at least in my uni, interactions with mental health person are confidential as long as one does not pose danger.

[flint thunder]

Thank you both

Is there any tips to not easly forgetting what you have learned today?

I've been using active recall and testing but mostly 3 days after studying I keep forgetting stuff

[daring parrot]

i want to go to college but my reading/writing level is 6th grade. I plan on majoring in math but gen eds/writing classes are gonna be a pain in the ass

how do i improve

[upbeat heart]

How do you know ur level is at 6th grade? My advice to you is keep practising and improving your read & write skills so that your brain will create new neuron around those and adapting to it, cmiiw

As long you have the discipline, you could tackle any subject

[tranquil coral]

[bronze pelican]

Arnt you going to go to community College ?

You will improve your reading and writing "level" there by taking the appropriate general education courses and completing course work in those courses

It doesn't make sense to put a time frame on this kind of thing. What you should probably do is call the counseling department of a local community college or something.

Part of the point of college counselors is to put you into courses that are at your level

You should specifically point out that you are worried that your reading/writing skills aren't as good as you think they should be for college level work. That way they know where you want to start.

[forest gazelle]

i've seen short and i feel like something is wrong
https://www.youtube.com/shorts/EABvwRgBalQ

iam familiar with the switch or no switch thing

but i don't think it applies here?

in the first iteration i've heard , in came in the form of a game show with 3 chest , one that comes with the reward , and when you pick a chest , it will open a chest that doesn't have the reward and is not the chest you've chosen

in the first itiration , it makes sense to switch cuz you have no new information on the chest you've picked , it will always not be openned

so it will stay a 1/3 chance

but in the video

inwhich instead of chests it comes in the form of wires , and wire that is safe is the correct option

it says that the bomb manufacturer informed you after you've made your first choice that one of the wire the dangerous

the difference in here that it is a possibility that the dangerous wire that they call out is also the one you've choosen

so if the one you've named is not the one the manufacturer named it gives you information that its more likely to be the safe one

making it a 1/2 chance

is what am saying making sense

in short , the fact that your picked is vailable to being rolled out , makes it that when its not picked out , it means its more likely to be correct

but when your pick is not vaiable to being rolled it , its will not give you any information on if its correct or not , cuz in all possibilities your pick will never be rolled out

This might read as a copy pasta, but it’s not. I believe we are living during the “Memeism”. In school, one learns about different art movements, which are art styles followed by a group of artists during some period of time. In the western world, you are probably familiar with the Renaissance, Romanticism, Dadaism, Pop Art, …, Modern art. In the eastern parts of the world there were similar periods of time were some art style dominated. Now, I posit that memes are the current art movement. It is an abstraction of what people normally consider art, born from the recent global interconnectedness through the internet. Paintings, music, etc are created to elicit some sort of emotion from the receiver. Memes do the same thing, but instead of being created by a single artist, they are created by a collective almost hive mind. What would correspond to a canvas in a painting would be a collection of memes. It has happened in the past for example with Andy Warhol, where people initially resisted ideas about what should be considered art.

My argument deteriorated near the end because I lost interest as I was writing this, but the main points are there

Will math stop being hard when i get good at it ;-;

Sometimes i look at the same problem for like 30 minutes and i have absolutely no idea what to do

Then the guy on the yt tutorial says "you could easily derive this" 😭😭😭

[amber fog]

I wouldnt say it stops being hard

You get better with practice

[true zinc]

this feeling won't go away ever tbh, you'll always have moments like this and some people will always find some stuff easier than others

[oblique sandal]

Which books are best to accompany Khan academy’s app ?

I’ve started the pre algebra course once finished I want to find a book that challenges the basics I’ve learned from that course

[sudden raven]

There is a website called openstax, they offer books from pre algebra all the way to multivariable calculus for free, and thats a great price if you ask me

I like to use em as a supplement to khan academy as well

[oblique sandal]

Thank you that’s helps a lot

[lost fjord]

maths never stops being hard, when you get better at maths you just start tackling harder problems

[mighty pilot]

But then older problems because often trivial I remember how much I struggled with injective surjective maps and stuff

Math’s quite comforting in this aspect as you still see some progress

what are chances my home built in 1973 has asbestos on the popcorn ceiling? I may have breathed it in when i was younger, will i die soon? im 20.

[unborn bronze]

Yes

there is also no known way to remove asbestos fibers from the lungs once they are inhaled, like what am i supposed to do

[solid snow]

how are you worried about this

[umbral lion]

im finna die soon bro, it takes 20-40 years for symptoms to develop

u can get mesetheliomioa or lung cancer

[solid snow]

ur paranoid af

[fast hemlock]

its pretty likely tho bro

[solid snow]

not really unless it was crumbling or loose

[stuck tendon]

can you tell me about it?

[fast hemlock]

i was watching cable tv for the first time in a few years and an ad for mesothelioma came up a few days ago. Now I figured out about asbestos today and how it can cause mesothelioma, it foreshadowing

"Asbestos fibers are too small to see with the naked eye", like what if ive been breathing it all this time

im practically dead

[old oak]

Look on the bright side, maybe you'll have a tragic traffic accident well before the asbestosis develops

[mighty pilot]

If you will die in 20 years live like you will die in 20 years and make the most all

It's okay, we must all accept that death is a natural process

[old oak]

It's all a marketing ploy by Big Demise

[fast hemlock]

This world is messed up why does my house have asbestos

[true zinc]

Because 50 years ago people didn't know how bad it was for your health

and because it's quite a solid insulator

[tiny ridge]

no, that message is from 누가 알겠습니까..

[old oak]

It's really wild, asbestos is an absolutely glorious material apart from that one tiny flaw.

It's light, flexible, easily shaped, excellent insulator, completely fire resistant, quite easily available

[tiny ridge]

so what you're saying is we should keep using asbestos but design better human lungs, good point

[upbeat kraken]

Hey

How do I progressive overload in mathematics

I’ve been learning exponents

Rational exponent specifically fractional exponents, I’ve learned addition subtraction division and multiplication

I did learn that

Now I’m onto radicals and I am learning adding and subtracting radicals

I learned adding and subtracting radicals

Now I am trying a mix of questions which use exponents and adding and subtracting radicals at the same time

I was fine with just basic exponents but when we have radicals we have base with exponents I realized I don’t know how to calculate and do order of operations with rational exponents with a base so now I’m going back and doing harder variation than what my book taught

Harder Learning means how to calculate rational exponents with same and different base

How far should I go with challenging myself out of the book

[quick beacon]

@bleak garnet can you reopen your help thread?

It locked due to timeout

[bleak garnet]

cant access

[quick beacon]

Just open a new one

[restive remnant]

sorry but I don’t know what nonlinear calculus is

can you explain it to me?

I want to learn aswell

[tardy storm]

i don't know it either, but I assume it's calculus without "linear" (i.e straight) lines. Things like polynomial/parametric differentiation/integration

quick google search confirms that, non-linear calculus is just calculus without straight lines

[tight copper]

Oh

[restive remnant]

oh so it’s more question solving based without the lines

it sounds a bit complex if you ask me 😭

[tardy storm]

yep, depends on the type of questions

I think an example question might be something like find the gradient of x^2 + 3x +5 at x=3

[restive remnant]

x squared plus 3x plus five at x equals 3

[tardy storm]

at a very basic level: it can escalate quite a lot from there lol

[tardy storm]

no, that would be the y value at x^2 + 3x + 5, not the gradient

you'd need to draw a tangent at x=3 on the graph, and find the gradient of that line

[restive remnant]

so this is linear graph based without the lines

and I would have to draw that out

using the equation shown

[tardy storm]

it still has lines, just not straight

[restive remnant]

okay, logically I would have to use the equation

to make it straight?

im a bit lost mb

[tardy storm]

what age/level are you currently learning content at?

this question would be GCSE level (so for age range 15-16 for Uk students)

[restive remnant]

im 15 years old

year 10

my bad 💀

[tardy storm]

nah it's good.

[tardy storm]

you draw the quardratic (x^2 + 3x + 5) on graph paper, then you find the point at which x equals 3.

you then need to draw a rough tangent at that point, by drawing a line that touches the graph once only

i'll bring up a photo

[restive remnant]

alright thanks.

[tardy storm]

well I can't upload photos here...

[restive remnant]

ah it’s alright im pretty sure I get half the gist of it

im gonna get some videos to work it on

gonna use your equation

[tardy storm]

sure. I got the answer if you want to check if you're right

if you want, create a help post and I can send the photo there

Should I be confident or nervous about college entrance examination? Cuz sometimes overconfident or nervousness could cause some harmfull effect. I need some mindset to view this college entrance examination

[tardy storm]

is it perchance the TMUA?

since I know that's one maths entrace exam coming up

[upbeat heart]

Nope, Im in Asean region sorry

[tardy storm]

ah. It's an international test anyway, but I might as well tried to have guess lol

[tardy storm]

but it depends how important this test is. You should totally be nervous, as it's only natural when it's a pivotal part of your life. But, if you have prepped all you can for it, then there nothing else you can do but wait

[upbeat heart]

I heard from chatgpt TMUA difficulty is 2.5 point higher than my entrance exam in the scale of 6 and 8.5 out of 10 ☠️

[tardy storm]

oh wow, for this year or for past years? they changed the TMUA this year which f**ked most people (myself included) over

but! what else can you do. How many colleges depend on this exam, and how many don't?

[upbeat heart]

Alright

[tardy storm]

when's the exam?

[upbeat heart]

Ups, I mean the difficulty comparation to my entrance exam and the TMUA sorry

[tardy storm]

so the TMUA or your entrance exam is harder?

doesn't really matter tbf

[upbeat heart]

It will be held in 3-4 months from now, but I am lacking on all of basics math to the point relearning from 10th grade math so gotta be nervous

[upbeat heart]

Indeed

[tardy storm]

but you got 3 months to prep for it, so you should be fine. Just put in 30mins-1hr daily for the first 1-2 months, then pick it up to 1-2 hours for the last month

learn in the first 2 months, past papers for last month

3 months is a lot of time. ~60 days , so that's 60 hours of prep, for just 1 hour a day

[upbeat heart]

So learning the basics rather than jumping straight to the question paper is an effective solution for someone like me?

[tardy storm]

if you need to re-learn it, it's better to learn it first. Otherwise you'll keep getting questions wrong from that topic and any linked ones

you need a stable base for you to expand for the test

[upbeat heart]

Dw, I study for straight 8 hours a day

[tardy storm]

oh yeah, asian reigon lol

[upbeat heart]

Alright, niceee, new insight for me, thank you very much tho

[meager knoll]

why would someone study for 8 hrs

[true zinc]

Don't burn yourself out and prepare a proper study regimen

[true zinc]

Because they actually care about their studies

[tardy storm]

it's asia reigon, makes perfect sense

[meager knoll]

i mean, studying more time doesn't equal to knowledge gained sooo

[true zinc]

It's less about it being "asia region" and more realizing that study is better, more fulfilling, and important than wasting your time on filthy video games or sports or whatever

[meager knoll]

i'm asian and i don't study for 8 hrs

[tardy storm]

depends what reigon; and what aspirations they have to get

[meager knoll]

pointless because my mind would be wondering what i can do with 8 hrs

giving myself a tight deadline helps me going

[meager knoll]

the latter is true

[upbeat heart]

Cuz I hv to learn another subject too, like english literature and my local languange, as well some problems that require logic

[true zinc]

Set a regimen for your whole day

[meager knoll]

i have nearly 9 subjects

[upbeat heart]

My parents force me so I leave with no choice

[meager knoll]

doesn't regimen mean a government?

[true zinc]

you're thinking of regiment

[tardy storm]

ya, and also a structure

[true zinc]

regimen and regiment are two different things

[upbeat heart]

Besides this is the price I paid for not studying seriously in my life (Im typically the student who never study in my whole life)

[meager knoll]

go to google and it says a government

but it also has another meaning - routine

[true zinc]

The price you pay/paid is not getting into a good uni

[meager knoll]

keep working hard

[tardy storm]

well, fortunately for maths you can just spam questions until you understand

[meager knoll]

study smart, not hard tho

[true zinc]

You cannot do this

[true zinc]

You should be doing both

[meager knoll]

what exactly do you mean by 'spam questions'?

[meager knoll]

no

[tardy storm]

to do as many questions as you can in a topic to learn and improve. It's the whole basis of past papers + practice questions

[true zinc]

They mean doing tons of problems back to back with no rhyme or reason hoping to eventually break through the wall of reasoning

[upbeat heart]

I think that makes sense too

[meager knoll]

so basically practicing?

[tardy storm]

yea

[true zinc]

You should have a solid ground understanding of the material first

[meager knoll]

or perfecting/mastering your 'art'

[tardy storm]

yea, which is why questions are good for re-learning a topic

[meager knoll]

real

[tardy storm]

so you can find any errors, and go over earlier content

[upbeat heart]

I've been thinking how textbooks could be improved, and how they are still basically the same thing they were since their inception thousands of years ago, even though technology now allows for so much.

Like one of the great improvements in PDFs is the hyperlinks that allows you to jump to given points in the PDF.

But there's other things that I have not seen implemented that would be useful in a digital book. The main one I've been thinking about is a filtering system: Usually textbooks evolve from much more concise lecture notes, and they become bloated because the author wants to include every possible use-case of the book. So it would be useful if books had a sort of "mask" that would mask anything that isn't in the original content that was delivered as lecture notes.

Another thing that I think would be beneficial in a digital textbook is a hovering feature for definitions like in wikipedia that shows you the definition in a mini window.

Another obvious improvement (although this one would be much more resource heavy to do) is adding videos instead of images.

I mainly wrote this because I've been reading textbooks on Ebook Central, and despite them having so much money and almost a monopoly on online textbooks, the user experience and content delivery is incredibly crappy. Although maybe it has improved a bit since the last time I was forced to use it.

i know of two online textbooks that are good

theyre somewhat like you describe

[ember lance]

Oh I am interested in seeing an example!

[solid snow]

https://sites.ualberta.ca/~vbouchar/MATH315/section_algebraic.html

[ember lance]

Oh yeah, these are pretty nice, you can get a template for them somewhere and make your own. I had one for my notes.

[solid snow]

but yeah every online text book that ive used other than these two has pretty much sucked

they make you jump around when clicking links to definitions, etc. instead of just popping it out like this

[north topaz]

https://discrete.openmathbooks.org/dmoi3/

wait that's the exact same format as this

Discrete Mathematics: An Open Introduction, 3rd edition
Oscar Levin

[solid snow]

This is like the optimal medium for (math) books imo

[ember lance]

Here's a list of some textbooks that use that format (PreText) https://pretextbook.org/catalog.html

Tbh I had forgotten about PreText untiil you mentioned it, and it seems to have advanced a bit since when I used it last

[neat lintel]

is it normal to take complex analysis before real analysis?

[solid snow]

No

[true wedge]

why would you take complex before real

@wild lantern

Hey @wild lantern I understand everything now my question is that with polynomial that is degree of 1 and monomic, it can be expressed in some format of which I don’t know name, the name was in my book but a polynomial with degree of 1 and monomic can be expressed as (a+b)(c+d) where first is divisor second is quotient so my book says:

Eg: 4x squared + 12x+9 check if (x+3) factor

4x squared + 12x + 9 = (x+3)(ax+b)

Expand

Ax squared + (3a+b)x + 3b

The x^2 terms on both sides must be equal, compare coefficients: a = 4

The constant terms in both sides should be equal 9 = 3b so b should be 3

The trinomial would be: (x+3)(4x+3)

Since when this trinomial expanded is not equal to trinomial e it is not a factor to given trio

That is what my book says is that faster or synthetic division

[wild lantern]

This feels slow

This is a valid method.

[upbeat kraken]

Yes

So synthetic division faster

I can’t inspect as I have to show work

[wild lantern]

You can do this in general also.

[upbeat kraken]

Ok

[wild lantern]

Say I give you a monic polynomial p(x) and I ask you, can you factor p(x) into a cubic times a quadratic? Then you can let p(x)=(ax^2+bx+c)(dx^3+ex^2+fx+g). Since p(x) is monic you can let a=d=1 from the start since a and d have to multiply to 1 anyway. Now you can expand out the product above and then compare coefficients. Either you get values for b,c,e,f,g that works or you get a system of equations with no solution.

But the system you get could be REALLY hard to solve so you usually avoid this if possible.

[upbeat kraken]

Ok

So if you had to pick between the two what would you do, the book method or synthetic division

For time efficiency

[wicked cedar]

Ahem Ahem your least fav dude has came back...ANY ADVICES ON HOW TO CONSUME 300+ PAGES in 14 days and answer any question that are asked about them ?

[upbeat kraken]

As you said to avoid the method you described because it is sustems of equations hard

[wicked cedar]

tricks and tips or schedule to do cuz im here getting bombarded thinking i aint gonna make it in time and panicking to a level i never experienced before

[wild lantern]

Yeah basically. I'd avoid it unless I had to.

If there's nothing else that works I might try it.

But you usually get a nonlinear system in several unknowns and that can be a rough time to solve.

[upbeat kraken]

Ok the. What would you pick between the book method or synthetic division if inspection not allowed

[wild lantern]

Idk I'd just try shit and see what felt fast/efficient at the time.

[upbeat kraken]

Alright cool

[wild lantern]

For this one if nothing else quadratic formula is ez

Often rational root theorem + synthetic division is also pretty easy

[upbeat kraken]

Yes

For finding if a expression is fully divisible into the polynomial expression I think synthetic division works faster for me

[wild lantern]

Sometimes factoring in general is kinda hard and there are often several ways to factor a thing that lead to the same result. So knowing a lot of techniques that you can pick and choose from is generally good.

[upbeat kraken]

Thank you DootDootee for helping me so much in understanding polynomial factoring and to check if a(x) is a full factor of p(x)

[muted wind]

yeah but 1+1 is 3 no? this has logic.

I would recommend you disable all the friend requests, so you can be entitled to enable it when you let someone send you one.

[upbeat heart]

Do you guys think that mastering in math could also lead to easier understanding in other subject? Since math enchancing one's logic

[solid bloom]

For sure, especially in physics related fields. Mastering calculus is really important for physics stuff

[north topaz]

I'd say no, you would be better served by studying other subjects

not only the subject content but their methodology, how we think about knowledge in other subjects as well as key concepts and connections that are specific to that subject

maths has a pretty unique way of viewing the world and it would be a mistake to think that you can directly apply this to other fields of knowledge

mathematical reasoning is only one kind of reasoning

the sciences have a completely different methodology, scientific method + peer review and all

[neat lintel]

Anyone here wanna do math?

[old oak]

That said, I would say mathematics gives one a very solid training in analytical thinking and deductive reasoning, which does come in helpful in many other fields.

Yep, fair point; in particular people often forget that mathematics involves very abstract systems, and applying those systems to real-world problems is often fraught with peril.
