[latent edge]

that's braindead ngl

but I don't blame u

[timid bronze]

Bro help.

[latent edge]

what function are you roughly "guessing"

[autumn nymph]

Im bouta tweak out

[timid bronze]

idk i was just told to draw a 2nd derivative. ;-;

[autumn nymph]

No

[latent edge]

let's assume that the curve is of second degree

the derivative should be lines

[latent edge]

form 0 - 100, what are you doing?

assume that t=100 is the vertex

[prisma plinth]

Borcherdo switch

[timid bronze]

Up

[latent edge]

physically

[autumn nymph]

concavity makes me get cavities

[latent edge]

slowing down or what

[timid bronze]

Oh

Speeding up

[autumn nymph]

uh

🤨🤨

[timid bronze]

What

[autumn nymph]

im bouta tweak out

its slowing down

[prisma plinth]

I am about to fall asleep

I need bed time

[timid bronze]

oh wait

thats right it gets less steep

[latent edge]

trace a line and see what is going on

[timid bronze]

Im half tired 😭

[latent edge]

yea

dw it happens lol

[autumn nymph]

Its ok

[latent edge]

yeah then what happens after?

[timid bronze]

100-200?

[latent edge]

yea

[timid bronze]

Well speeds

[autumn nymph]

🙋🙋

me me me

[latent edge]

yeah

[autumn nymph]

0

[latent edge]

now you have a rough sketch of the derivative

[autumn nymph]

😼😼

[latent edge]

if I can only pronounce correctly today

[timid bronze]

so like would this be that part

Or am i being dumb again

[latent edge]

graph y=x^2

and the derivative

[timid bronze]

Well derivative would just be 2x

like that

[latent edge]

there we go

[autumn nymph]

😼😼

[latent edge]

idk does that answer your question?

[autumn nymph]

no

[latent edge]

not u

[autumn nymph]

id be confused

[timid bronze]

U helped a bit thx

[latent edge]

did u gets learn how to get the acceleration from the velocity?

or the displacement from velocity

[timid bronze]

well i figured acceleration is just the derivative of velocity

[timid bronze]

no not this

unless u mean he taught us basic physics

which i already know bc i took phy

[latent edge]

correct

so the trend is derivative : disp -> velo -> acc

how about backwards?

[timid bronze]

Uhh it was

position s(t)
velocity s'(t)
acceleration s''(t)

[latent edge]

yeah

now the question is, given the acceleration function, how do you obtain the velocity function?

[timid bronze]

Uhh isnt this integrals 😭 ..

[latent edge]

yeah

[timid bronze]

Ya i havent gotten to tht part yet

[latent edge]

I was about to make you discover that part on your own

like give u a simple example then u be like "OHHHHHH AREAA"

[timid bronze]

Im not that dumb ik what integrals mean ..

[latent edge]

good to know

that you are smarter than all of my physics class last year

[timid bronze]

Yeah meanwhile im crying over this assigment

Tysm triangular intrinsic shoulder muscle.

[latent edge]

tfw I thought I'm done with assignments

4 new assignments dropped in the same day

[timid bronze]

They doing u dirty

[latent edge]

real

[fresh comet]

I just submitted my pset 2 min before deadline

I feel you

literally had an existential crisis for the last 3hrs

[latent edge]

I literally was crying over the system prog assignment for a week

[gritty crater]

I always have anxiety when submitting assignments too late. What if your computer suddenly decided to slow down

[latent edge]

The prof doesn't do anything in the lectures other than being like "guys let me tell u why this movie clip is related to system programming"

[timid bronze]

Grrrr.

Im GONNA BEAT THIS SYSTEM UP

[latent edge]

Submitting is satisfying regardless of the grade

[latent edge]

Fuck this shit

[fresh comet]

what is this

[latent edge]

Is the original graph curvy?

[fresh comet]

why are all online submission sites so annoying lol

[latent edge]

higher u had to see my integral calculus online assessment

It will make you rethink of life

[timid bronze]

its so confusing to me with the axises bc we're told to just focus on this part

[fresh comet]

no thank you

[timid bronze]

i feel u

me rn

[fresh comet]

what is f

what does it look like

[latent edge]

integrate
writes the correct answer
WRONG YOU DID NOT WRITE X^2 INSTEAD OF X^2

[fresh comet]

[timid bronze]

Wait

Now its 67% correct.

[latent edge]

lmfao

[fresh comet]

that's a 100% improvement at least

[timid bronze]

Bruh

[fresh comet]

what

isn't that the same curve as earlier

[timid bronze]

what

no

thats the whole graph

but we have

2 separate axises

[fresh comet]

I meant for f'

your f' has only 1 root, but the original function has two extrema

[timid bronze]

Top of my assignment says
0.6666666666666666 of 2 points atm

Bc of this problem

[latent edge]

this is fucked up

reminds me of physics

[timid bronze]

Im so confused ;-;

[fresh comet]

I literally don't even understand what the question is asking you to do, ngl

[latent edge]

Do u know the majority of students failed physics because of the online homework

[timid bronze]

How about i give up and quit

[fresh comet]

oh the online hmw for my physics class was pretty terrible

[timid bronze]

thats the problem

[latent edge]

Did u guys use pearson for physics

[fresh comet]

yes

I hate Pearson

[timid bronze]

No

[latent edge]

My condolences

Pearson fucking sucks

[timid bronze]

ASSIGNMENT DUE IN 40 MINS.

[latent edge]

Where is jay

[timid bronze]

AAAH I HAEV

[fresh comet]

the number of extrema that f has is the number of roots that f' will have

[fresh comet]

ignoring inflection points but w/e

your f' has only 1 root, but there's 2 extrema for f

[jaunty ibex]

Deltoid fuck you fuck you fuck you I got this problem WRONG again FUCK FUCK

[gritty crater]

Try to locate the the points where the slope is 0

[jaunty ibex]

WHY IS LOG(N!) = O(NLOGN)

[latent edge]

bro what did i do

$\log (n!) = \sum_{k=1}^{n} \log k \le \sum_{k=1}^{n} \log n = O(n \log n)$

[fathom swallow]

Matroid

[timid bronze]

I hate digital homework

[jaunty ibex]

WHAT THE FUCK

I've been thinking in a very complicated way about it

THIS MAKES SO MUCH SENSE IM SO DUMB

[jaunty ibex]

Wtf is this

online homework?

[timid bronze]

Yea

[jaunty ibex]

lol id just quit

fuck this

[timid bronze]

Real

[jaunty ibex]

@latent edge

another stupid question im so sorry

If Q_k is integers n for which n is not divisible by d^k how do you calculate the natural density

so that I can get a formula for $\sum_{Q_k} 1$

[fathom swallow]

vero

[latent edge]

Find the Dirichlet series for Q_k

[gritty crater]

You should correct your f'(x) graph first. Its graph should cross the x-axis two times at the points where the slope of f(x) = 0

[latent edge]

$\sum_{Q_k} n^{-s} = \prod_p \frac{(1-p^{-sk})}{(1-p^{-s})}$

[fathom swallow]

Matroid

[latent edge]

Can u go from there

[jaunty ibex]

how did u even get this

yk what i give up for today

good night

[latent edge]

Follows directly from Euler products

Just see what happens with the terms

[timid bronze]

@fresh comet Well this is what i got on the assignment

Ill take it. im going to bed

[autumn nymph]

should i go to bed

[fresh comet]

that's pretty good, all things considered

[fresh comet]

have a good night ally!

[jaunty ibex]

@latent edge ok got it

Thank btw and sorry for bothering you too much today like a bitch

[timid bronze]

I still have to fix up my bed cuz i washed my sheets 😢

[jaunty ibex]

gn ally ily

[timid bronze]

@prisma plinth @latent edge @fresh comet Thank u guys for help

Gn vero ilyt

[fresh comet]

I didn't even do anything

[jaunty ibex]

delty did a lot of shit today and i feel bad

[latent edge]

Happy to help

[latent edge]

You're welcome

[latent edge]

This is great considering the average grade was 30 in my physics class

Aside from people cheating to get the 4.0 GPA for med school or whatever

[timid bronze]

Oh ya u too @gritty crater

[timid bronze]

u still gave pointers

[timid bronze]

Oop

[gritty crater]

Getting 4.0 GPA but don't know any shit about the subject is so embarrassing

[limber thunder]

i mean for that kinda people it's "cool" and "gaming the system" or smth

they genuinely dont give af about the subject and just want the clout that comes with being a future [insert career that pays a fuckton here]

[latent edge]

"I graduated top of my class"

Everytime they say this I cringe inside

[old oak]

I graduated in the top 83% of my class

[azure sleet]

Not to be rude, but people boasting their 4.0 GPA while not totally understand what they learnt are annoying and embarrassing

Reminds me of my former classmate, who once has claimed to be "my friend".

[gritty crater]

Agree. I just care about knowledge

[azure sleet]

They even have asked me to give them my work so that they could copy mine.

They claimed that they "learnt from solutions", which was quite unbelievable.

[north topaz]

and I have over 300 confirmed kills

[gritty crater]

Seriously, I don't know how to deal with this

Is there a smart way to say no

[north topaz]

just say "no"

or no thanks

don't explain yoursel

[gritty crater]

These guys are so persistent ngl

[azure sleet]

I already said "no", but they have once stole my work in pdf files saved in the google drive

[latent edge]

Mods, ban this person

[north topaz]

@ moderators

[azure sleet]

My supervisor even asked me if I gave someone my work, I told them the truth, yet they just let them pass with a minimum passing score.

I didn't even think he would believe me, either.

I was surprised with how awful their learning attitude actually was in our sophomore year in our university.

[limber thunder]

oh this kinda thing is a classic lol

[azure sleet]

They even told me they regret for always procrastinating right before the final in our first semester in our sophomore year.

[solid snow]

that seems like something that could and should (?) be reported

[azure sleet]

Yeah, I couldn't believe the chairman of our major would provide them fellowships in our first summer break.

[gritty crater]

Classic

[solid snow]

this sounds like there’s something else going on behind the scenes

[limber thunder]

in my experience that kinda attitude persists unless like, a big chunk of the class calls them out and ostracizes them for it

[azure sleet]

I eventually got to learn that sometimes people who are very close to us can be our enemies.

[limber thunder]

never had this issue in ugrad but my physics bros did with one particular dude who was kind of a tryhard and routinely copied HWs

same person was also under investigation for harassment and other crap within the dept

eventually not much happened sadly

[solid snow]

oh god

[limber thunder]

uni bureaucracies have little incentive to care

and quite on the contrary they usually do have incentives to just pass stsudents and keep them paying tuition

so in the end it's best to be aware that this kinda stuff happens, don't lend HWs to anyone, generally trust no one lol

except for your close friends to some extent

[azure sleet]

Yeah, in the end, I also got to set my boundaries with these people.

[solid snow]

i never let anyone copy regardless of their relationship to me

id rather help them through it

[limber thunder]

I mean yeah copying is a no-no anyhow lol

[azure sleet]

Same

[limber thunder]

but honestly some people will do anything to get further away

like my friends had this personal discord server where we hung out and sometimes they worked on uni stuff on stream, naturally some not-so-close people joined in on a one-off basis too

on one occasion one of these people accidentally played a recording of a convo in VC through speakers and the mic picked it up

on another occasion, another person copied some HW problems through stream while my friends were working on them

some people lol

[azure sleet]

If I couldn't keep up, I would rather just drop the course and do it next year.

I hope this was not a bad move.

I have dropped most courses I took in the peak COVID season.

I studied abroad in Taiwan, where there were no indigenous cases for like a year since spring 2020.

Since COVID invariants hit, we ended up having online classes for a semester until vaccines came out in that country.

Thank goodness, they eventually gave up their study in the second semester in our junior year.

[latent edge]

I got a 4.0 GPA, I don't need to learn. They all care about the GPA

vibes

[azure sleet]

Scoring lower than these people kinda disappointed me honestly.

Thank goodness this doesn't only apply to me

[azure sleet]

Fr

[latent edge]

"All this smartness and I got +10 higher than you LMFAO"

[last vessel]

The problem is when schools and uni and companies also care Abt GPA

[azure sleet]

Yeah, extrinsic motivations get to them.

[gritty crater]

I agree. I kind of regret letting my friends copy my works so now without me they can't even do some basic things about the subject

[fresh comet]

higher? ?

[azure sleet]

At least, my ADHD frees me from being extrinsically motivated

[fresh comet]

higher!

[latent edge]

analytic number theory

[azure sleet]

Being intrinsically motivated is more feasible

[latent edge]

My ADHD kicks in again

[spare gale]

same

[latent edge]

I love seeing them struggle on proof-based math

[azure sleet]

Same, LOL

Glad 1-D to 3-D PDE got them smoked.

I love the part where they low-key blamed our engineering math lecturer for being "weird" in class.

[spare gale]

can yall tell me wht calculus is?

im a dumass

[azure sleet]

Hardened dental plaque?

[gritty crater]

My teacher didn't even need to ask. He just asked the guys who were suspicious of copying some questions and if they couldn't answer then they were dead

[azure sleet]

Or continuous change of something, e.g., shapes?

[vocal vessel]

That’s calcification. You’re thinking of the tool used to measure the linear dimensions of a hole or object.

[spare gale]

i know that it deals with the finding and properties of derivatives and integrals of functions by methods originally based on the summation of infinitesimal differences..........

[azure sleet]

WOAH

[spare gale]

shits memorised

[gritty crater]

That's basically calculus?

[azure sleet]

I wish I had these kinds of teachers

[gritty crater]

Maybe you will find out soon enough. There are all kinds of teachers in college

[azure sleet]

Yeah, afaik, we use derivatives to find slopes, and we can use integral to find the volume of an object

[spare gale]

its memorised.........i dont actually....like Karen Uhlenbeck level understand

[spare gale]

mmm....

ig making games is the only thing im good at

[azure sleet]

Aw

[gritty crater]

In short, calculus is comprised of limit, continuity, derivative, integral, series, and properties of those things......

[old oak]

That's calipers. You're thinking of the internal diameter of the gun barrel bore.

[limber thunder]

yeah, that's basically it

[spare gale]

biee yall

[limber thunder]

another way to look at it I guess is from a more geometrical point of view

[vocal vessel]

You get the assignment 🤣😜

[spare gale]

cya

[old oak]

Less shitpostily, that's the usual meaning of "calculus", yes

[limber thunder]

calculus is (in a vague sense) about the geometrical properties of functions, particularly those that can be quantified by some kind of limiting process: is the function increasing/decreasing at some point (derivatives), what's the cumulative area under a function's graph (integrals) etc.

[spare gale]

ig this is what happens when i make games during class

[limber thunder]

but the key thing is the use of limits to define derivatives or the Riemann integral, and that's kind of the common theme you'll see along calculus

how to deal with the "infinite" and "infinitesimal"

[azure sleet]

Lebesgue integral?

[spare gale]

oohh

[limber thunder]

this is a good summary but I can't stress enough that limits are the key concept behind all of the rest

[azure sleet]

Am I lost?

[limber thunder]

since this integral is defined as a supremum of certain things it can also be kinda seen as a limit

a limit of integrals of simple functions even

[spare gale]

😭🫡

[limber thunder]

but usually in a first course on calculus you'll see the Riemann integral, simply because it's easier to understand the definition geometrically

[azure sleet]

Mhm

To define limit in a simple way while being a great stepping stone

Have you read the whole thing? 🤔

[vast wraith]

no

i think i scratched my cpu while pasting it

its time for the cyanide

[fresh comet]

L(V, W)

or most people call it Hom(V, W) I think?

[fresh comet]

yes V and W need to be fin dim too

[fresh comet]

actually, do they?

[true zinc]

What is L here

[fresh comet]

linear maps from V to W

[true zinc]

So Hom is the set of all maps from V to W

I mistook it as equivalent to V* for a sec then remembered that's maps from V -> F

Makes sense

[fresh comet]

that makes sense

okie dokie

<@&268886789983436800> is this okay?

While the topic of random algebra notation is on the table, what’s your preference, $\mathbbm{k}^\times$ or $\mathbbm{k}/{0}$

Nope
Compile Error! Click the reaction for more information.
(You may edit your message to recompile.)

[glass peak]

Because I definitely didn’t get wildly confused for a minute trying to work out what the group of units of a field is earlier

[vivid halo]

if you're talking about the group of units then k^\times is pretty much always preferred

also worth mentioning k/{0} makes no sense you probably meant to write k{0} or k-{0}

[potent cobalt]

On lined paper, how do you guys write math when dealing with rational numbers?

[vivid halo]

Uhh I would write it normally if I were using lined paper for some reason

[potent cobalt]

Like a/b or a on top of b

[vivid halo]

Either is fine

a on top of b you just have to write a bit smaller

For some things this is fine for some things it’s annoying

[potent cobalt]

Yeah, idk if it's me, but it gotta be like mad small

[vivid halo]

Sure so write a/b then if it’s too small

[potent cobalt]

But this is also death because it's hard to tell what's happening LMAO

[vivid halo]

You can write this in ways that make it clearer

Like you can write a higher up than b even in an inline fraction like this

If you have an inline expression involving lots of parentheses and also slashes then yeah sometimes this is hard to read

Sometimes I will make the slashes extra bold

[potent cobalt]

Straight up I think best case is just downsizing tf out of your handwriting n doing a on top of b

My issue just stems from poor handwriting I feel

[vivid halo]

Yeah this is what I generally prefer

You may also consider just not using lined paper

Then the issue goes away

[potent cobalt]

Word, I heard graph paper solos

[vivid halo]

Nah just use blank paper

Lines are unnecessary

[potent cobalt]

I like the structure that lines give ngl

If I do blank paper my shit isn't straight yfm

[vivid halo]

Fair enough, I find them too constraining

I think if you practice writing on blank paper your writing will straighten out

It’s definitely a fixable thing

[potent cobalt]

That's a thought

[vivid halo]

dotted paper is good too, maybe the best it's just harder to find

it has the benefit of graph paper without having such distractingly bold lines

[potent cobalt]

Word

Yo do u think having numerator on one line n denominator on the next would be kinda aids

[vivid halo]

oh yeah that's bad don't do that

[potent cobalt]

Lmaoo word

@pulsar pagoda how do you delete voice packs in honkai star rail on mobile? i'm on ios. my installed voice packs are EN and JP. i'm currently using the JP voice pack. according to a redditor, i should see a delete button when i tap on the EN voice pack. however, i only see a cancel button when i select the EN voice pack.

[pulsar pagoda]

thats done through the settings

give me a sec

ill need to check on my pc in a bit

[vale plover]

i think i did things through the settings?

[pulsar pagoda]

yeah sec

ill get to it now

I had a fun convo

have not played in a while

But I think there is a setting thats called clear local data or something

[vale plover]

ye i'm on mobile

can u screenshot the steps?

[pulsar pagoda]

yeah

im downloading star rail on my desktop

[vale plover]

the thing i've also heard is that people are able to delete voice packs on desktop, but not on mobile for some reason

it's kinda variable

[pulsar pagoda]

mm

maybe deleting the app data from the OS settings?

[pulsar pagoda]

https://www.reddit.com/r/HonkaiStarRail/comments/12zbf6t/deleting_en_voice_pack/

reddit to the rescue

[vale plover]

yeah i looked at that exact thread but it doesn't work

again, not desktop, but mobile

weird

@pulsar pagoda

[pulsar pagoda]

im googling

[vale plover]

i also tried asking on the official honkai star rail discord, but not much luck there either

there are about 100 messages regarding this topic on the HSR discord

[pulsar pagoda]

yeah

im seeing it is a thing

how much storage is it taking?

https://www.hoyolab.com/article/28328551

they say clearing cache...

[vale plover]

~3 gb

[pulsar pagoda]

but I dont think thats a HSR specific

[vale plover]

jp voice pack takes ~3.88 gb

but i'm interested in deleting the en voice pack

[pulsar pagoda]

yeah im about to finish the download then I have to do the JP voice packs

https://www.reddit.com/r/HonkaiStarRail/comments/1cu7vjc/ok_they_need_to_add_the_old_quest_data_removal/

mm

they report the same

this sucks

[vale plover]

yeah unfortunate

[pulsar pagoda]

did u clear the cache?

thats the other thing they say works

[vale plover]

i've only barely started the game; i don't expect that to be a huge factor tbh

[pulsar pagoda]

yeah u got a lot of catching up to do

https://tenor.com/b1LuI.gif

[vale plover]

that's good

good way to spend time walking to class from parking

i mean i have a new phone but it's good to optimize every bit of space you can

[pulsar pagoda]

yeah I get it

also iOS storage is

kinda cringe

[vale plover]

very inaccessible ik

i had a samsung before i got an iphone hand-me-down

now i have a new iphone

yeah maybe when I get a job

if my business goes all right I can buy it

pixel?

[vale plover]

yeah

[static loom]

I did this last year, I have a pixel with grapheneOS and it works great, haven't had a problem with it once

best thing imo is google play sandboxing, I can download an app and not give it network permissions

that ends up not just blocking telemetry but also they try to make apps as small as possible so you won't cancel the download - this means they have to download the ads afterwards, but they can't so you can play/use many apps without ads that way

also you don't have all that garbage annoying bloat apps you can't delete too

[pulsar pagoda]

that sounds nice

why did this fail? ( I want to draw it in desmos

The left side must be r

you can convert it to 2 graph

[quaint cipher]

still didnt work

[gritty crater]

Try sin(theta)^3

[quaint cipher]

worked, weird, why lol

[gritty crater]

Maybe you missed the parenthesis

Try sin^3(theta)

[quaint cipher]

No I mean, It already worked but Idk why the former one sin^3theta doesn't work lol

[gritty crater]

Maybe you missed the parenthesis around theta

Because theta from 0 to 180 not 0 to 360

[quaint cipher]

oops im being silly

nvm lol

[sudden oar]

guys i have an idea

what if black holes are just the same as any regular planet, just with a lot of mass

and the reason why it's black is because when atoms are closer together they erratically move faster and faster

and the light can't reflect off of the atoms fast enough because they're moving too fast

[flat harbor]

nope

[sudden oar]

aww man

i just thought of it because i had an idea yesterday that anything traveling faster than light speed could just be black because light can't reflect off of it

or the light can't catch up to it i mean

[flat harbor]

what are open / closed sets?

What property makes a set closed rather than open?

[shadow flax]

A set is open if every point in the set has an open ball contained in the set.

Intuitively, if you have some set A, and let a in A. If you can draw a circle centered at a such that the circle is contained in A for all a then its open

Looking to get into calculus on Khan Academy from algebra 2/trig ASAP (albeit my basis in algebra is a bit weak now), would you guys recommend I start with the "Get Ready for Precalculus" course and then move onto AP Calculus AB/BC?

[vast wraith]

what does he think of math

[limber thunder]

sounds good

you can probably skim over the precalc course and focus more on the things you struggle with e.g. algebra type things

and then move to calc when youre ready

[serene cave]

if you're not taking the class in a school bc is just ab with more content and the only reason they're separated as separate classes with bc having all of ab but more as college board intends it to be calc 1 and calc 2 but if you're self studying this is completely irrelevant to you, and yes this is confusing

is that so?

okay well, what do we mean by “anti-humanities”?

[vast wraith]

one of the (emeritus) profs at my department is so based and claims in one of his books mathematics without its history is like a horror movie without audio

[hardy iron]

Make sure you know your basics

[solar pumice]

Fair enough, any other recommendation? I’m trying to get both better academically and well for fun

[hardy iron]

Once you get good at highschool level then you could start reading textbooks on each topic ig

[true zinc]

science requires mathematics

you, by definition, cannot be a "science dude" without a strong understanding of mathematics

[north topaz]

that's too harsh

[north topaz]

org chem tutor on YouTube does algebra 1/2 and introductory calculus well

[brave shell]

Never met aristotle. I would argue what he did is not meaningfully distinct from science.

[solar pumice]

[true zinc]

Bio still requires mathematics, my friend

[solar pumice]

Science dude as in interested into science.

[true zinc]

Yeah and what about when you start digging and you see it's all maths in a trenchcoat

[solar pumice]

Everything does?

Everything revolves around math

[true zinc]

Yep

[solar pumice]

Which is why I’m trying to dig deeper into it

Computer science, biology (not so much), chemistry, physics

Everything requires math, my point is that you don’t need to be completely strong in mathematics. You just need to know the fundamentals.

[north topaz]

agreed

it's super important to avoid an all-or-nothing approach

focus on understanding specific bits that are related to things that interest you!

the rest will come eventually

[vivid halo]

not really

I don't think it's possible to be scientifically literate without also having some minimal level of mathematical literacy

[north topaz]

as in, they're trying to improve their maths for that reason

you, by definition, cannot be a "science dude" without a strong understanding of mathematics

I'm referring to this comment being too hard actually

that's a reasonable take

🔥

[true zinc]

we have quite frequently; then we proceed to throw overpowered methods at the problem and it somehow works

[lucid raven]

That makes me feel better

[vivid halo]

depends on how often you're forgetting this

it's normal to forget stuff like this sometimes, but maybe not so good if never remember it

[lucid raven]

I mean I hadn't thought or used this in a very long time, it just kind of caught me off guard because of how easy it is

[true zinc]

we forgot how to find the vertex of a quadratic recently and pulled out the second derivative test 💀

technically, first derivative would have been enough ig because quadratics only have one inflection point

Spent longer than I should on 7 math questions and it made me realize that I struggle at math because I only focus on how to solve things and not why

I just watch what the guy in the video does and in my mind I go “this question on my hw looks like this so I’ll just do this!”.

There’s no deeper understanding so it doesn’t embed itself into my memory

[tough island]

Right now I am in community college, want to pursue a PhD in computer science, am eager (and passionate) to get ahead on my studies in regards to the math. I have plenty of curriculum and know what to the learn, I am just not sure exactly how I know if im, good at discrete maths? When do you decide when self learning math, you've reached the required skill level to move on?

[warm torrent]

I don't move on until I've completed a lab or project that uses the method or formula. I encountered a similar issue previously. During my calculus course, the concepts were not clear to me until I engaged in a construction role focused on low-voltage systems. I am now capable of calculating the necessary conduit volume (using washer method for finding the volume of a solid of revolution) to accommodate 40 cables per floor across four floors, given that each cable has a diameter of 5.8 mm. Additionally, I can determine the total amount of cable required for procurement. This calculation is predicated on the configuration of two Intermediate Distribution Frames (IDFs) per floor, with half of the total cables from each floor directed to IDF A and half to IDF B. The distribution of cable lines is as follows: three lines for studios, four lines for one-bedroom units, six lines for two-bedroom units, and eight lines for three-bedroom units, within a building that contains 160 rooms. The room ratios per wing (representing half a floor) are structured as 4:3:2:1 for studios, one-bedroom, two-bedroom, and three-bedroom units, respectively. It's about a six month project to complete 4 buildings with 3 people.

Doing unnecessary and long calculations that turn out ot be spectacularly wrong is very much the mathematics experience, at pretty much any level.

[gritty crater]

And now you need to retrace ALL of your steps

[vast wraith]

i really had no good reason to do those calculations so i won’t bother finding the mistake(s)

[pure hollow]

No we submit the wrong calculation and Gaslight the math community to believe that it's right ~~thats what happened to complex numbers ~~

[old oak]

Indeed, Cardano didn't notice that he'd accidentally taken the square root of a negative number, and was too stubborn to admit his mistake, and now here we are.

Delusional numbers.

[vast wraith]

they are very chill as long as you don't make them feel threathened

[gritty crater]

Yeah. Bee wouldn't randomly sting you

[pure hollow]

Wasps on the other hand...

[old oak]

I don't think there was much controversy around them, especially compared to stuff like Cantor's theories on infinity or the uncovering of paradoxes in set theory.

I think there was quite some drama over the autorship of the solutions to cubic or quartic equations, and complex numbers play into that a bit

@vast wraith can probably say more

[vast wraith]

that's a very funny story

i very much recommend øystein ore's biography of cardano

it's a great read

he talks a little but not a lot about complex numbers, just like negative numbers they have probably been around in calculations for a long time but they would not be like something you used in public, as their ontological status was seen as dubious (and they placed a lot of emphasis of this strict correspondence between mathematical and physical entities)

[old oak]

Which is interesting, because I feel the ontology issue entirely goes away once you interpret complex numbers as points on the plane.

They admittedly don't make much intuitive sense as "quantities", the geometric perspective is much more helpful

[vast wraith]

ahem i just realized i forgot a “not” in the above, fixed now

but i should get to work i’ve been goofing about for three hours now woops

[civic flicker]

Ok, but which part are you having trouble understanding? What I wrote earlier is just a theorem or a lemma. If you want to prove it yourself you can prove it, it's definitely worth the try!

Maybe see how this works with some integers as an example. It often helps! Mathematics is not a spectator sport sometimes!

Are you doing a square well?

[brittle socket]

What are you doi-

Nvm you're doing discord addict things

[mighty ridge]

random thought but is there a proof that if you take the numbers 1-9, you can't make 3 equations using each numbers once of x+y=z

[hardy iron]

The proof is bruteforcing

[mighty ridge]

yea but is there some number theory proof

i guess u could look at parity

[main elbow]

you can certainly make progress by considering mod three

ive reduced the possible solutions to either the zs must be 3, 6, 9 or are each different mod 3

[static loom]

I think we can do it by adding all the equations together, best case scenario has the smallest 6 numbers paired to make the 3 largest numbers but 6*7/2 > 7+8+9

pretend that makes sense, proofed 😌

[main elbow]

yep aha nice

wait

its not true...

but some minor modification is probably good

we can say we must have 1, 2, 3, 4, 5 among the xs and ys

ok no theres an even easier way aha

1 + .. + 9 = 45 is not divisible by two, thats all you need

[static loom]

that doesn't prove anything either

inequalities basically live in a different world than modular arithmetic

oh I think I misunderstood what you were saying

we could take each equation, write them as x+y-z=0 and then add them all up mod 2 and we get 1=0 mod 2 since there are 5 odd numbers.

if it wasn't what you meant I'll just give you the benefit of the doubt anyways

[main elbow]

Yeah basically

a + b + c + d + e + f = h + i + j
Then 45 = 1 + ... + 9 = a + ... + f + h + i + j = 2(h + i + j) to be overly explicit

not a bad annual salary

[limber thunder]

If I want to be an "expert" in analysis and algebra, the Math Major is my best option?
I am also interested in cool engineering things, like electronic circuits or programming. But I feel the need of study both subjects in depth.

I live in Mexico, so, the concept of Major and minor in the Universities doesn´t exist. You choose a whole grade of 4-6 years and that's it, you can't combine subjects between grades.

Well, there are optative subjects that are "far" from the main grade. For example, in the study plans of Mathematics grade there are often 2 or 3 Physic's grade optative subjects, like classical mechanics or electromagnetism. But that is so far away like the flexibility that the universities in US offer.

I know that the Engineering grades have Calculus and Linear Algebra subjects in the curricula, but in my experience on a Engineering grade in Mexico, both ones aren't treat with deep, just mechanizing the formulas of Calculus and the Matrix Operations, but don't seeing so much of cool theory.

For engineering degree, those course are computational-based not proof-based. If you want to study it more in-depth. You should consider follow math degree

it is interesting to compare with Jacobi, who came from a very well off aristocratic family, but as the socio-political climate shifted throughout his life, he found it more and more difficult to provide for himself and he eventually joined the political revolutionary side

[cursive sail]

Math: "i'm gonna prove that this works"
Engineer: "someone proved that this works. I'm gonna use it to build X thing"

[vast wraith]

historically it’s often been the other way around as well

fourier famously was rather mad at mathematicians complaining that the theory of fourier series didn’t have much of a rigorous example when its virtues was plenty clear from its success in physical application

[neat lintel]

Does anyone have something enjoyable to do for the weekend?

[latent edge]

Analytic number theory

[neat lintel]

learning or just practicing?

[latent edge]

Both

[neat lintel]

good luck then lol

Do you have anything except maths?

to do I mean

[latent edge]

Yeah

Bombieri Vinogadrov theorem

Which is also analytic number theory

:3

[neat lintel]

[jaunty ibex]

Deltoid autistic

[solid yarrow]

hello vero

:3

[jaunty ibex]

:3

[solid yarrow]

What are you up to vero?

[jaunty ibex]

Buy groceries

[solid yarrow]

I gotta do that too

Eventually

:(

[jaunty ibex]

:3

What are you doing now

[solid yarrow]

I just did my anki cards.

I was thinking of either

Going eep

or doing CA

[jaunty ibex]

Eep

[solid yarrow]

where i am terribly stuck

and don't know what to do

._:

[jaunty ibex]

rip

[solid yarrow]

yep

If I don't have any clue tomorrow

I will ask in RCA

or I will go mental for sure

When does next term start for you btw?

[jaunty ibex]

Wdym

school?

I don't go to school :3

[solid yarrow]

I thought you were in uni

[jaunty ibex]

nu

[solid yarrow]

Hm

[jaunty ibex]

@latent edge what are u up today

[solid yarrow]

I swear I avoid pinging ppl. I fee like a burden when I do

._.

[latent edge]

Tedious homework, slamming desk when applying to internships

then analytic number theory to get back my sane mind

@solid yarrow

ping :3

[solid yarrow]

._.

[solid yarrow]

You stuck too?

[latent edge]

Analytic number theory?

[solid yarrow]

Ohh

I read it wrong

[latent edge]

Yeah it's a research problem

[solid yarrow]

....

[latent edge]

[solid yarrow]

Are you stuck on it

?

[latent edge]

Yes

[solid yarrow]

How do you deal with it?

Like ofc work on it for a bit. But what if you don't see a route (which is why it's a research problem to being with)?

[latent edge]

Just work on a different one :3

[solid yarrow]

...

[latent edge]

I usually read a lot of papers around the problem and see if something comes to mind

[solid yarrow]

I am currenlty working on solving improper integrals in CA. And I get stuck on every single one.

._:

[latent edge]

Is it for school?

[solid yarrow]

My insanity level is increasing as we speak

[solid yarrow]

No

Self-study

:3

[latent edge]

Based

Can you show me the integrals?

I do a lot of cursed ones in my work

[solid yarrow]

Are you familiar with the fresnel integrals?

pretty basic I guess

[latent edge]

Yes

Usually with contour integration stuff, it boils down to choosing the best contour that makes your life easier
