[lapis hull]

LOL

[granite crag]

😂

seriously though thanks for all your help

[lapis hull]

ofc np!

[alpine moat]

😭will I have to do this if I take up engineering

[lapis hull]

no lol

[alpine moat]

Then where is this part of math and when even is it called

[granite crag]

Engineers only have one model so they don't care about model theory

[alpine moat]

🫠🫠🫠uhmmuhm

[granite crag]

one model as in the physical universe

[alpine moat]

🫠 everything u say is wayyy to advanced for me

[granite crag]

(I'm probably oversimplifying)

[alpine moat]

It's soo cool to be a math person

[granite crag]

I know right! I wish I could be a math person then I would be cool

[alpine moat]

[granite crag]

ok and we can't have say n < m because then we would have phi_n = psi_n be a proper prefix of psi_n ... psi_m

similarly we can't have n > m and so n = m

[lapis hull]

Yeah p much

It's more like you continue and so you must have m>=n but then the empty string would equal psi_{n+1}...phi_m

But whatever works

[granite crag]

yeah that's simpler lol

Hello. In big O definition (f(x)<=C g(x), why do we multiple g(x) by C?

Does not it give us a different function than g(x)?

[surreal sapphire]

yes, but the whole point is looking at behavior "at infinity"

constant there dont change anything

more concretely, you want to compare the growth of functions

multiplying by a constant shouldnt change that behavior

there is an equivalent definition that relies on limits and its more clear there

[alpine jolt]

On the wikipedia big o notation is described as a mathematical notation that describes the limiting behavior of a function. What does growth of function have to do with it?

[surreal sapphire]

defining growth in isolation is kind of hard

but when we want to compare growth of two functions, the idea is to look at the limiting behavior of their quotient

so function f grows faster than function g is f(x)/g(x) tends towards infinity
if g grows faster, the same limit will go towards 0

and when its some kind of constant term, we want to say they grow at the same rate

[tough ember]

Hey, Im a high schooler that has a hobby of math and I recently started looking at the impossible 3x + 1 problem it occured to me something I thought was pretty cool. You can see it in this bad drawing I did, but basically you can think of this problem as just a big figure made out of trapezoids (of course this isnt up to scale)

What keys would you put on a keyboard layout made to type math. (Assuming you don’t need keys for every single Latin or Greek letter)

[hardy iron]

Is it time to move to Linux? (I used to dual boot Windows and Arch)

Windows has become bad with their spyware and AI thing

[limber thunder]

I use a debloated win11 on desktop and arch on my work laptop

[neat lintel]

I use NVIDIA gpu, last time my experience with Linux was either buggy or laggy even though I used the official NVIDIA driver from their website

Tried on both KDE and Gnome

Gnome was the smoothest

[limber thunder]

I think nvidia drivers have gotten better over time, a friend drives theirs daily on arch

[neat lintel]

I'll do more research and see if I should go back to dual boot again and only use Windows for Adobe apps or games

[rain wharf]

You missed the cutoff. The time to move to unix (Linux or Mac OS) was yesterday.

[limber thunder]

I mean they do have a history of trying to push telemetry, ads and crap features since forever, to me Recall is just the new bloat lmao

[neat lintel]

Does this mean Edge is also a spyware?

I use it everyday because I don't like Chrome

[limber thunder]

you can just get an "old" version that's still supported and apply a debloat script or use https://atlasos.net

if you're worried about what happens once like 22h2 or something is unsupported then yeah I would look into gnu/linux

saying anything in win is "spyware" is kind of a strong word, but yes if you're worried about enterprises collecting data I would look into alternatives

[neat lintel]

Wow, I didn't know about this

Thanks!

[gleaming idol]

anyone know if its a good idea to study for a gen chem college level exam 8 days before it?

[north topaz]

study while it's still 8 days and not the day before

[limber thunder]

better than studying 1 day before

sniped

yeah it's not optimal but better late and still reasonably early than never

[gleaming idol]

Ok

hopefully i get a B at least

I normally do 14 days before but yeah this is bad

[old oak]

8 days before is still 8 more days than most students

[fresh comet]

I have a midterm tomorrow and only now am I seriously preparing for it

and then I have a midterm the day after that I haven’t even thought about yet

[jagged forge]

higher flying by the seat of his pants, my man

[vast wraith]

i wish i had midterms maybe that would make me actually study

[wooden stag]

Are u undergrad

Hello

I have a question.

I wanna prove that a function f is continuous, and I have
x^2 - 1 ≤ f(x) ≤ x^2 + 1.

¿What?

What is "oic"? XD

I speak Spanish but I´m studing English. I don´t know many words.

Well, In general.
¿is the following claim true?
If g(x) and h(x) are continuous and g(x) ≤ f(x) ≤ h(x) is true for all x. Then....is f(x) continuous?

That is my question.

I need that for solve a problem.

¿is "u" equal to "you"?

A

[stoic roost]

-0-10 <= 10 <=10-30+

is there links to list of useful equations like seen in textbooks?

[tough island]

{x ∈ R : sin πx = 0} = {. . . , −2, −1, 0, 1, 2, 3, 4, . . .} = Z

Not sure if I got the answer correct when I checked the solutions page to the book, but I also put other special sets other than Z. I put Q and R.

I figured since sin pi is always 0, and anything multiplied by 0 is 0. Then it wouldn't matter if iit were just an integer, it could be a decimal or fraction etc. Am I correct or am I missing something? Is it that the author just put Z for the sake of simplicity or is my logic wrong? I just want to make sure before I move on.

nevermind I see where I got confused

[leaden jasper]

i don’t think so. take for example the function f(x) = 0 if x rational and f(x) = 1 if x irrational, e.g. f(π) = 1 but f(7) = 0. now if you let g(x) = -x^2 and h(x) = x^2 + 1 (both continuous) then g(x) ≤ f(x) ≤ h(x) for all x but f(x) is not continuous

[burnt ledge]

sin πx doesnt mean (sin π) x (in which case you'd be right) but what they mean is sin(πx), whjch is zero iff x is integer

[neat island]

AAAAAAAAA thanks.

¿Do you know about Cauchy´s equation?

[leaden jasper]

you mean the additive one, f(x) + f(y) = f(x + y)?

[neat island]

Yes.

[leaden jasper]

yes, i know, it has only f(x) = f(0)x as a solution if f(x) is continuous

[neat island]

Yes yes...Well, I have a problem and its solution, but I dont understand it.

[stoic roost]

i need different logarithm rules for graphing Quadrant 1 and Quadrant 4

[leaden jasper]

what do you not understand?

you can show the problem/solution

[neat island]

Yes, wait please.

I can´t send photos.

[leaden jasper]

you can send in DMs

you can’t send photos in this channel apparently (kind of annoying)

[neat island]

AAAAAAAAA.

Well I´ll share the link

https://artofproblemsolving.com/community/c6h73056p422498

That is the problem.

The solution that I want to understand is the last one.

[leaden jasper]

the calculus proof?

[neat island]

What?

[leaden jasper]

ah, no, sorry

wait, let me read

[neat island]

The last solution is from AlexanderMusa.

He used Cauchy.

[stoic roost]

any one know the asnwer to my question?

[tough island]

That makes a lot of sense thank you!

[silver bison]

Is there a known nonrecursive equation for the Sterling Numbers of the First Kind?

[dawn copper]

is there any rule that cauchy schwarz is only applicable for positive values?

[old oak]

Depends what exactly you mean.

[hexed pier]

It shouldn’t be. If you’re trying to play games or use windows apps expect a bad experience but you would still get a bad experience on windows for different reasons

There’s a chance it’s an arch bug your experiencing though

[leaden torrent]

dont really think comparing the ease of using nvidia cards on windows to linux is sensible lmao

on windows its plug-and-play

like at worst you need to click the update drivers button in geforce experience every few weeks

and CUDA works out of the box

[hexed pier]

Took me about the same time on fedora. I didn’t have to log into anything

[dawn copper]

umm actually i wanna solve this, and i was thinking if we can use cauchy here https://discord.com/channels/268882317391429632/903486480075354182

[leaden torrent]

and you had no issues afterwards?

every time ive set up CUDA drivers on linux computers at work it is a mess

[hexed pier]

Yep 😎

[leaden torrent]

like multi-day project as i squash bugs

[hexed pier]

I used all kinds of obscure GPU libraries no problems

[leaden torrent]

(not all at once, but like, a bug will come up 3 days later that i need to fix)

whereas on windows everything just works

[hexed pier]

I’ve had to reinstall windows and even had my graphics card physically damaged from updating windows(most of the monitor port don’t work any more)

[leaden torrent]

thats bizarre

[hexed pier]

Though to be fair I reinstall Linux quite a lot. I would still say I experience slightly more bugs on windows but the real issue is that unlike Linux, you can’t really fix them you just let it get progressively worse

If I get an error on Linux I look it up on windows you probably won’t even see it. You’re not looking at the terminal

[hexed pier]

But to be fair to Linux I take less care of it don’t turn it off use privileges where I shouldn’t do stuff I don’t understand

[hexed pier]

Wait are you using the proprietary drivers? The open source ones can be clunky

[fierce eagle]

yes

https://en.wikipedia.org/wiki/Cauchy's_functional_equation

[fierce eagle]

not cauchy schwarz

[vast wraith]

help going on a random walk through my obsidian graph gave me a bit too strong of a reminder that i’m afflicted by such a bad case of digital bibliomania

[thick yacht]

What is an obsidian graph?

[vast wraith]

obsidian is a note taking software

my graph is such a mess

[surreal sapphire]

you should at least use MOCs

[vast wraith]

the majority of these nodes are books and articles

[surreal sapphire]

hm ok, maybe then it makes sense

but uhh

can you extract any information from this

this looks even worse than "just a mindmap"

[vast wraith]

yeah it’s really not helpful at all

the graph part i find is just fun

in a stupid sort of way

i have only read an exceedingly small part of the resources i gather in my notes…

the hope is that someday i’ll just stop looking for literature and content myself with what i already have at hand

[vast wraith]

also what does this mean

[hexed pier]

How do you get different colours?

I find it better if you atomise things into the smallest concepts you can and put them in your own words. When I go over something again instead of looking it up, I search my notes

[vast wraith]

yeah i agree small works best

[vast wraith]

grouping by tags

also i really should sleep woops

[hexed pier]

Id need to categorise links for it to be properly useful. But don’t want to start again idk if there’s even an extension for that

[slim burrow]

Guys. I have a question.
I want to have a career as a science researcher.
I would like to study Maths as my Degree Bachelor, but I don't want (well, it isn't in my future plans) to have a career as a Pure Maths researcher, maybe as a Computer Science or even in Physics, but not in Maths, but that doesn't means that I don't want to course what a Math Major studies.

I live in Mexico in a state called Veracruz, specifically in the port of Veracruz. This isn't the best place for students, the capital of the state Xalapa, has better installations and reputation in education, and in all the state, it is the only place to study philosophy or science degrees as Maths or Physics.

Here in Mexico, our maximum place for study a science career is in the capital, Mexico City, where is our National Autonomous University, UNAM. Maybe for engineering studies is not the best place, in that case our Polytechnical Institute, IPN, could be a better choose.

I have the opportunity (I got accepted, that isn't so much difficult as Ivy League admissions in USA or something like that, but it still being no possible for the majority that applied) to study Maths on UNAM. The problem is that, is in other city and specifically Mexico City have the reputation to have high living costs, that doesn't mean that is impossible to study and being foreign, the problem is that my family doesn´t have so much budget, and make this movement implies to just focusing my whole budget in the rent, eat as much two times at day on school cafeteria (luckily, the Science Faculty has a very complete food order on $40 MXN, that is a very good price, taking in account that a food order on a "home food" restaurants are about $70 - $120, and as an approximal, I will live with less than $100 MXN per day) and school supplies, and that's it, nothing more.

Living in the capital of my state Xalapa would be the same case, in fact, it would be maybe exactly the same economical situation, because UNAM give many helps for students, as subsidizing the school food and with just $0.10 for inscription. In Xalapa, there is the University of Veracruz, UV, where the costs for food are without subsidizing and the University, even being public, has a price for semester, the lowest for not material demanding courses since ~$3,000 as Maths until medicine that costs ~$8,000 the semester (not so much taking in account the prices for privates Universities in Mexico could cost from $20,000 to $100,000 the semester), but at the final, every expense adds up. The only difference could be the costs and time to return to my home. From Veracruz to Xalapa, my family could take me to there and return me with my luggage. In the case to living in Mexico City, the trips in bus could cost ~$1,000 and I am limited with the things that I could carry with me.

Here in Veracruz, I could receive my bachelor degree in Engineering colleges, as the UV Veracruz Region and the Technological Institute of Veracruz 🐟. The problem with this regional universities (my experience) is that they aren’t as excellent as one would expect. Sure, someone could distinguish from the average and have a success story, but the modus operandi of these universities is in most of the case, graduate people to work in the regional jobs, that this isn’t bad for people that wants a great economical lifestyle, but for the people that want to continue their academic career, it is a situation that hinders us more than helps us.

So, as I said, I want to study Maths at Major Level, but as I said too, I don’t want to continue a career as a Pure Math Researcher. Genuinely, I want to research in the Engineering field, specifically in mechatronics. Luckily, in Mexico, the government offers scholarships for the postgrads students. Here in Mexico, the best places to study a Master and then a PhD are UNAM (again XD), the IPN and a “subsidiary” and at the same time independent from the IPN institute called the CINVESTAV. All of them are in the capital Mexico City, but in this case would be different, because my family would not pay more for my livelihood because I will receive a schoolarship. So, an alternatively could be receive my engineer degree here in Veracruz, and then wait for my postgrad studies to go to Mexico City in the Universities that I truly want.

What do you think?

Should I have to do the sacrifice to study in the capital a science major as I would like (with all the economical lack and costs for my family that it will represent)?

Or the more prudence decision would be study an Engineer degree here in my city and then wait for my postgraduate studies?

[static loom]

sounds like a tough decision

[warm umbra]

made you look 😉

[upbeat spindle]

this got me

[limber thunder]

knowing UNAM there's a chance that the prestige alone might be worth it, could increase your chances of getting into a better grad program in the future

studying abroad can be tough but doable, some people work part-time during undergrad esp. in LatAm

[pulsar pagoda]

Depends on the uni also

It might be the case that teachers at unam are assholes and dont want to give classes in schedules that allow this

This is pretty much the case at UCR

[ember lance]

CIMAT is in Guanajuato and w.r.t. mathematics it's as prestigious if not more than UNAM afaik

However one of my HS friends graduated from UNAM in math and later got Fulbright so that's another option

[solid yarrow]

[past pecan]

why do y'all have iphone

[tender tulip]

@gusty socket would (+, -, -, -) have signature (0, 1, 3)?

[dusty path]

damn that's a planet

[gusty socket]

what is the 0 for

@tender tulip

[tender tulip]

Degenerate basis vectors

[gusty socket]

R^4 is all you need

[tender tulip]

I.e max dim of norm 0 subspace

[gusty socket]

oh

[tender tulip]

I’m just using Sylvester’s notation

(n_0, n_+, n_-)

[gusty socket]

(-,+,+,+) is also (0,1,3)

[tender tulip]

hmm

I just did a bit of quadratic forms stuff in hs but I don’t remember much

[gusty socket]

hmm

maybe ti's (0,3,1) actually

[tender tulip]

I’m pretty sure the number of basis vectors that are 0, positive, or negative corresponds to the max dim 0/positive/negative subspace

[gusty socket]

yeah it'

okay

[tender tulip]

Once again, haven’t done this for a while

I did some silly quotient space form nonsense with unimodular form bs

[sharp moss]

@quick beacon high school level bro

[quick beacon]

as in learning algebra, precalculus, or calculus?

trig?

geometry?

[sharp moss]

I suck at everything

[quick beacon]

Have you tried Khan academy?

[sharp moss]

Nah I have not

[quick beacon]

the thing about just watching youtube videos, they might be useful for stimulating your curiosity and helping with your familiarity in some of the language that mathematics uses. But it won't make you actually better at doing math.

Only practice does that

Khan Academy has videos, but also assignments

[sharp moss]

I just want to learn the concepts

[quick beacon]

then just passively watch some khan academy videos. They are typically a little dry though

just have realistic expectations on what you can get out of them

anyway, I'm going to go do laundry now, best of luck!

[sharp moss]

Oh ok thanks for your advice bro

[quick beacon]

ciao

[zealous garden]

Lorentzian smay

[zealous garden]

The usual ordering is +,-,0

Smay is currently 1,3,0

[zealous garden]

(3,1,0)

[zealous garden]

Not so

Consider (+,-,0) as (1,1,1), and consider the 2D subspace generated by {e3,e1+e2}

Simply being null isn't enough for the degenerate vectors

They have to have a dot of 0 with everything

[gusty socket]

thanks

[zealous garden]

The reason for this ordering, at least afaik, is that we often speak of Euclidean spaces (n,0,0) and nondegenerate spaces (p,q,0), so it makes the most sense to order it (p,q,r) and have the shortenings (p,q) and n

[tender tulip]

Shit that what was I was looking for

[zealous garden]

Degenerates are tricky because if you add more degenerates they might suddenly not be degenerate

(p,q,r) can always be embedded in (p+r,q+r) desu

[gusty socket]

oh ic

yeah

[sonic sentinel]

how do people even use notes? like at all?

the only times i remember using notes are to remember, at a broad level, what i studied. most of the stuff i wrote was not necessary in this use case

[limber thunder]

to keep track of what you've done or to write down your own account of e.g. math stuff

lately I've used Obsidian a lot to summarize papers or make notes about the big picture of some topic, linking to said papers internally

[sonic sentinel]

i've also heard of students repeatedly reading/reciting their notebooks to study for a test (in the context of research saying not to do that)

[main elbow]

@shut thunder idk if ive missed any developments in what youve been doing, but if you recall i mentioned that recurrence relation a(n,m) = a(n-1, m-2) + a(n-1, m-3)
well ive (kind of) solved it ! if you find the taylor series of (x^3 + x^3y + x^4y^2 - x^5y^2)/(1 - xy^2 - xy^3) the coefficient of x^n y^m is a(n, m) - which just as a reminded is "the number of occurrences of n in the set A_m"

specifically this is for when A_m = f(A_(m-2) U A_(m-3))

shouldnt be too difficult to get some form of taylor series tho ill lyk if i make nay progress

[rose zodiac]

I'm a 9th grade student in a school that I consider pretty difficult From what I've heard grades 11 and 12 are really hard due to academic pressure with SAT and APs I am thinking about starting AP's now with physics AP 1 to ease off pressure later on. My father is an engineer and has experience teaching all types of physics and maths. I heard that precalculus is heavily recommended to be mastered before physics AP 1. So where and what source should I use? and how many hours of studying would it take to master precalculus?

@wanton ruin

[wanton ruin]

If your are already comfortable in Algebra, pre-calc shouldn't be hard. Ideally if you can take AP Calc and AP Physics concurrently that's a good place to be. You can get out of the two biggest flunk out courses in engineering - calc and physics. See if your Dad agrees.

[rose zodiac]

My dad doesn't mind anything

Wdym by flunk out though

[wanton ruin]

My world is Operations Research, Stats and Simulation modeling. (retired after 40 yrs in practice)

[rose zodiac]

Cool

Sorry though I didn't understand what you meant by flunk out

@wanton ruin

[thick zealot]

Is it normal to prepare for an exam and still do poorly?

[static loom]

sure

[thick zealot]

How sad

Besides the fact that you fail the exam it is sad that your teacher has an idea that you do not know

[static loom]

it's not enough to prepare, you have to prepare correctly

[thick zealot]

What do you mean by “correctly”?

[static loom]

I don't think you actually care or should care about what is "normal"

[static loom]

whatever gets desired results

[thick zealot]

Perhaps the pressure to do well on an exam plays an important role.

RAHHH

i talked a while ago about how my teacher gave a random surprise benchmark assessment which lowered everyone's grades by ~10% (except the people who cheated)

this sounded like a lot of bullshit so i emailed the studysync posing as a teacher asking how i should use the benchmarks

they said a lot of stuff but the important thing is this

"Since students will not have been exposed to all grade-level standards, it can be used as a progress monitoring tool rather than a summative assessment."

i don't know what's the next step to take after this

right now we're on a week long vacation

should i wait until the vacation finishes? what do i do then? show it directly to the teacher and hope she cooperates? what if she doesn't?

[cloud basin]

its just infinity

if 1^inf is undefined, why is 0^inf defined

[gritty crater]

I think it is interpreting 1^inf and 0^inf in the context of limit

Because if 1 is a number 1^inf = 1

[brazen mulch]

same with 0^0, which is painful

1^inf doesn't work only because that 1 can just as well be 0.999... but not enough 9s to make it 1

[gritty crater]

But infinity is not a number so I don't know whether we can do 1^inf

[hardy iron]

I consider infinity a number

Just not a real number

[cloud basin]

Infinity is a concept

[hardy iron]

Numbers are concepts

What's your point?

[cloud basin]

[boreal whale]

I mean it is defined as element that extends the real line, it's not a number itself

[hardy iron]

It's not a real number but it's a number for me

Feeling math

I'm into that

[hardy iron]

Yeah

[unborn meteor]

3 isn't perfect

[boreal whale]

mathematically it isn't, you are correct

[cloud basin]

what is perfect

[unborn meteor]

equal to sum of divisors

Infinity arithmetic be like: inf + inf = inf, inf - inf = inf, inf x inf = inf, inf / inf = indeterminate

I believe that there exists a perfect odd number

[boreal whale]

Daring, aren't we

[north topaz]

your reasoning is based on faith

[cloud basin]

↑

no proof of it

[brazen mulch]

perfect

[cloud basin]

ngl i dont think my question has been answered yet

[brazen mulch]

you... gotta cope

[cloud basin]

i wont be able to sleep today

[brazen mulch]

:3

[cloud basin]

[gritty crater]

Infinity is not a number so different software or calculator will have different ways to handle these cases

[hardy iron]

If you can do arithmetic on it it's a number

[cloud basin]

so..it depends?

[gritty crater]

Most calculator will go with 0^inf = 0 and 1^inf is undefined

[cloud basin]

yea

[unborn meteor]

i think i^inf is 0 is that true

i mean its indeterminante but it makes more sense for it to be 0

[cloud basin]

but in 0^inf inf is still not a number

[hardy iron]

Why is this kind of funny

[hardy iron]

0^inf is mostly talked in the context of inside a limit

[unborn meteor]

i actually have reasoning

[gritty crater]

Well, if you use limit you will see that when the base go to 0 and the exponent go to inf then the whole thing go to 0

[cloud basin]

ah okay

So the answer depends on the context

[gritty crater]

Yeah like 0^0 = 1 in combinatorics

[hardy iron]

I like to think 0^0 = 1 everywhere

[gritty crater]

Iimit also suggest that 0^0 = 1

But maybe that will break something so 0^0 is keep undefined in general case

[hardy iron]

Yeah for lim x^x as x -> 0

[brazen mulch]

0^0 always breaks everything as of now
I'd want it to be 1 universally and create a permanent disconnection

(Proof for Proposition 1.8. "If m is an integer, then (−m) +m = 0")

Let m ∈ Z

(Axiom 1.4) M + (-M) = 0

(Axiom 1.1 (i)) (-M) + M = 0

is this correct

[neat lintel]

$m + (-m) = m*1 + m \cdot (-1) = m(1 - 1) = m \cdot 0 = 0$

How common and affortable is to study math major maths for ourselfs by books and internet?

[neat lintel]

math books are expensive

if you're immoral you can just buy a tablet and import pdfs

I wouldn't recommend doing it though because pirating is bad

[limber anvil]

You can get almost all online for free

[neat lintel]

yes

illegally

[limber anvil]

It’s just companies working for a sole purpose of money

They make books for $5 somewhere in china

Sell us at 20x markup

[neat lintel]

yeah ofc it's cheap to produce the books

what they're selling is the knowledge

[limber anvil]

Which you can get for free

Not to target companies but most of them don’t care on you they just want money and profits

So yeah

[neat lintel]

yh i mean it is what i do, just download free pdfs and import on my ipad, never buy a book again and get a superior experience to using a book

[limber anvil]

Hahaha nice

[slim burrow]

Well, I download books to trail them, and them when I decide which book to study I buy it physically

Like the Introduction to Real Analisys of Bartle and Sheldon Axler Lineal Algebra

[neat lintel]

if you don't have ethical issues with pirating, then just buy a tablet and import the pdfs

not only is it better than using a book physically it's also cheaper

and you get a nice tablet for entertainment

Win-Win-Win

[limber anvil]

My school gives them out for free online ones

So it’s good

[slim burrow]

Well, but my question was more referred to the time and effort that someone have to put. Taking in account if we are currently studying a engineering degree.

[abstract cairn]

Hello, I'm planning on learning calculus but am having trouble deciding how. The first thing I thought of was simply learning the formulas and maybe getting a vague understanding, then trying to learn to visualize and understand them on a deeper level. The 2nd thing I thought of was the opposite, focusing on and understand everything on a more abstract level first. Just curious what anybody thinks would be either better, faster, or both. That might have a few interpretations,
so basically should I watch The Organic Chemistry Tutor, or 3b1b calculus videos first. (Of course Ill look for other resources besides just those)

[wanton ruin]

I would recommend Gilbert Strang for Linear Algebra - especially as it applies to linear and non-linear practical optimization in OR. Bartle is the ONLY real analysis book I own.

[wanton ruin]

Corvus - we used George Thomas - standard calc text at U of Illinois and our calc teacher in HS used in for AP Calc - one sixth of my HS class went to U of I. Made sense.

Rapidoso and corvus - great questions but keep in mind, my context is as an engineer not a math major. Very few engineers are ever asked to write out a mathematical proof but, that said, doing so sharpens your mind so when you are forced to argue something, having a good base in proofs and real analysis is useful.

[abstract cairn]

Thank you!

[wanton ruin]

Hello, I would like to ask a question but I am not sure of the right channel can I just ask it here?

Does anyone here know about any math research programs for high school students talking place during the academic year?

[smoky quarry]

RSI maybe

[clever widget]

spivak

[abstract cairn]

Thank you! Ill definitely check that out, but from what I heard about it, its a bit more conceptual. Do you think its better to start off with that? I was just wondering if it might be easier to wrap my head around those more complicated concepts after learning simply about "how to do it". Or if its better to start off with the deeper concepts.

Basically is the "take in information now, make connections later" approach faster, or is "make connections as you're doing it" faster. It feels like it takes forever to learn something when you try to do the latter.

[clever widget]

Hi derivada

[sly jungle]

Sigh, doing Dummit Foote and stuck a bit + bored. How hard is the Group Actions chapter? Say compared to the previous chapter 3 on quotients and homo/iso-morphisms (which is where I'm stuck for a bit).

[ember lance]

Dummit and Foote can be daunting at times, if you haven't seen Keith Conrad's notes before, here they are: https://kconrad.math.uconn.edu/blurbs/

[limber thunder]

prob same difficulty as the previous chapters, it's not particularly hard but expect to work through a bunch of examples and exercises to really understand the concept of group actions

[sly jungle]

thx, I was also using Nick Nathan Kaplan's (from UCI) course page (which uses DnF) and he also references Conrad's notes, so was using them. They are quite nice indeed.

[sly jungle]

thx, was wondering if I should take a break or can plough thru it. Helps to know if it is similar in difficulty or higher...

Yay! One of the best

[limber anvil]

But I’m only at 235 chapters tho

😭

[willow wadi]

Ah vol 2 is great

[limber anvil]

After the volume one ending it hooked me

[willow wadi]

Personally I found each volume to be better than the previous ones but each to their own

[willow wadi]

It's really good ending one thing RI does masterfully are the volume ending are absolute peak fiction

[limber anvil]

Yes you are right

So good

But it’s like one piece on terms of length so people dont read it

Me personally I never liked books but my friend recommended me this and I changed my mind hahaha

[willow wadi]

It's more closer to haiime no ippo but yeah since one piece is also long it's fair enough

In terms of length

[willow wadi]

Haha yeah I also didn't like books that much but after reading RI that opinion has changed

[limber anvil]

[willow wadi]

Anyhow I gotta read the other RI

Hi quite chat

What have you bee up to this weekend?

[sharp oar]

Hello 👋🏼
I’m currently looking at all the channels here in the math discord 😅 I’m looking for people I can help (I honestly only help if I know the topic 😭)

How about you ?

[neat lintel]

Lol, sounds like you enjoy helping people and doing maths when you're free

For me, I am listening to music and chilling

So are you planning to pursue a maths degree?

[sharp oar]

I don’t think I am very smart for that😭

I’m pretty decent at math but I don’t think I can survive if I will pursue a math degree

I already graduated from a college accounting program 2 years ago HAHA

I feel too old sometimes 😆

[neat lintel]

Hahaha, you can do it lol if you want. I thought you were a high-school student

😅

Because of your role

Where are you from kanin?

If you don't mind

[sharp oar]

I’m born in the Philippines 🇵🇭
But I now live in Canada ‘cause my family and I migrated years ago !

[neat lintel]

Cool, how's it going there for you?

[boreal whale]

Eh, few people are math geniuses. I really do believe that everything can be learnt. As for “feeling too old”, I’ve met quite a few people who have started their math degree after having already done a different degree. There is no age limit in education 😄

So if you want it, you can definitely go for it. If you don’t want it, then that’s a different story ofc

[neat lintel]

I agree

[verbal cove]

hey everyone

[fresh comet]

hello! welcome to mathcord!

[willow wadi]

Hello higher!

How are you doing?

I'm doing alright

how're you?

[old oak]

Validation at last

[fervent pebble]

oh my god sor-ry im trying to listen to a lecture

[old oak]

Also it should go without saying, but nevertheless: the irony of accusing others of groupthink in the same breath as using the word "woke" as a pejorative unironically.

[limber thunder]

this is just the evolution of

ok. Something that disturbs me, there is a 'gang' here and they clearly message each other for these sully pile-ons, it's really really offputting and the disturbing thing is whether mods are in on this as well. In which case privacy is really really compromised

[old oak]

I mean, the whole group did think he was being a racist asshole.

The worst groupthink is among the algebraists, surely

[fervent pebble]

this is crazy bc we are well out of sully’s heyday too

like if your post is getting 6+ sullies in 2024 that’s the same as 15+ in 2022

And certainly not in Chinese

Russell would be proud

[fervent pebble]

oh, in such an inefficient language, never could that be

[old oak]

Although Russell was against racism and in favour of gay rights, so probably too woke for that guy

[fervent pebble]

wait, really?

based russell

[old oak]

I mean, as much against racism as it was possible to be in 1932

So still quite racist from the 2024 point of view

[fervent pebble]

well, in favor of gay rights is still pretty good

was euler racist i'll be really sad if he was

[old oak]

https://en.wikipedia.org/wiki/The_Bertrand_Russell_Case

[fervent pebble]

In the books, Russell advocated for sex before marriage, homosexuality, temporary marriages, and the privatization of marriage, among other things

look at him go

[old oak]

Almost enough to forgive the Principia

[hexed pier]

Don’t look up Aristotle

[fervent pebble]

oh i already know he was a bitch

[hexed pier]

After reading Plato‘s Republic, I think we should burn all philosophy and start again

[old oak]

He might have been too early for that, I seem to recally racism as we understand it is a surprisingly recent invention (started developing throughout the 18th century and really took off in the 19th)

[fervent pebble]

oh, really??

[old oak]

See this, for example https://www.projectmanifest.eu/the-genesis-of-the-notion-of-race-17th-18th-centuries-en-fr-2/

[fervent pebble]

that's surprising

[old oak]

There's also tales of wealthy black people from Haiti (then Saint Domingue) sending their children for eduation in Paris, and noting how much less racist Paris was than the colony.

[old oak]

See also, the concept of nation which is very firmly a 19th century invention.

[fervent pebble]

clearly i need to brush up on my history

[old oak]

It's a supremely unpopular view among STEM people, but I believe the neglect of humanities is one of the greatest mistakes we've been committing as a society.

[fervent pebble]

i agree!

i love reading abt history and art and things like that

i just hate writing essays about things im not inherently interested in

[hexed pier]

I’ve heard that a bit. I’m wary of general statements about history although our current ideas about racial categories are definitely different

This seems to be an example of Roman racism https://penelope.uchicago.edu/encyclopaedia_romana/britannia/miscellanea/geography.html ( you won’t regret reading this )

I can’t find it, but somewhere else there was a Roman talking about how galic people(sorry I’m dyslexic) had more blood making them hotheaded and the Africans less making them more intelligent with Romans conveniently being the best of both worlds

[old oak]

Oh yeah, sure, generally people inventing justifications for disliking the other is something that probably predates recorded history

[hexed pier]

Yeah, but specifically here it’s targeted at race and not nationality. Which goes against the idea it’s a new notion

[old oak]

Yeah, fair, it's probably more accurate to say that it had a big comeback in the 18th and 19th century, mostly in connection with slave trade and collonialism.

[hexed pier]

I was going to say the language you used “took off” that seems like a much more believable claim I guess I haven’t read directly about it in academia so maybe that was how it was meant

[hexed pier]

If the square root of -1 is imaginary, does that mean the square root of 1 ( 0 ) is a real number

[old oak]

How do you define the square root of -1?

Also the square root of 1 is 1, and it is a real number

[sharp mulch]

The square root of 0 is 0 which is also a real number

[hexed pier]

The Calculator says it’s zero

[sharp mulch]

The square root of 1 is not 0

[old oak]

What does your mathematical reasoning tell you?

[hexed pier]

I didn’t feel like thinking

[old oak]

In that case does it matter?

[sharp mulch]

......

[hexed pier]

I assumed it would be an edge case and didn’t really think it through intuitively It’s really dumb

[limber thunder]

you probably did something wrong, by definition sqrt(1) should be such that sqrt(1)*sqrt(1) is 1

that's not the case for 0

Hello

Could i ask questions in here or should i ask it there?

How could i know if my research has been done already? Or has not been done already.... Comprehensively

Is it only google scholar? For someone without research institution

[old oak]

A lot of math research is also published on arxiv and vixra

[midnight flame]

thanks

Can mathematicians (with job) search more comprehensively to ensure there is no research that had happened already.

Could they?

[sharp mulch]

Google scholar is a good source

Part of being an academic is keeping up with journal publications so ostensibly you see what work others are doing

[old oak]

Being at an institution probably means you have a better network of contacts you can ask directly about the stuff you're working on, if you're unsure whether it's already been done.

But also typically you know whether what you're doing has already been done before you start out, because you're reasonably up-to-date on developments in your field

[midnight flame]

Allright thank you

Anyone interested in co-writing after verifying my claims? as long as you have college in math. and I could verify it

As my argument was that you could predict the number of odds in a collatz conjecture till a number would reach to 1.

for example 10 has this many odds. It is a pattern i had discovered. Proved true till 1-11

I am quite confident on higher numbers.But i did not verified it yet.

[sharp mulch]

For any collatz conjecture related work, you should verify at least up to 10^12

[midnight flame]

I don't know how to code

[sharp mulch]

No time like the present to learn

[midnight flame]

Allright, thank you

If i learnt to code. anyone interested?

[static loom]

no thank you

[midnight flame]

May i ask why?

But allright. Could anyone verify that such research had not existed yet. Thank you.

[static loom]

people working on the Collatz conjecture are a dime a dozen, it's just that you probably don't have anything particularly new to say about it

[old oak]

I think your best bet is to start with this and then refine your search https://scholar.google.com/scholar?hl=en&as_sdt=0%2C5&q=collatz+conjecture&btnG=&oq=Collatz+Conjecture

I mean, your best bet is to work on something other than Collatz conjecture

[static loom]

the fact that you haven't invested the time to learn how to program to test it is a bad indicator. If you're having fun that's fine, but publishing is another level altogether

[midnight flame]

I am learning how to program...

And yes I am just having fun.

[static loom]

oh ok cool, in that case don't worry about if someone has done it before cause they probably have. Discovery is a reward in its own right

Lovely ppl seem to be in here

[stuck compass]

[tired karma]

what is 6/2(1+2)

[old oak]

It's what you ask when you can't come up with a better trolling attempt.

It's the lack of originality that's so disappointing, really

[neat lintel]

I think they asked it in the other discussion as well but not sure, I just so a solution of such a thing there

But didn't go up to the chat

[restive magnet]

sorry to interupt. do any of you know a reliable site(ranking) for undergrad physics program. i know that ranking isnt everything but im just trying to get a grasp of the schools. I also want to ask about whether graduate school should be considered when choosing uni for physics. I'm not sure if i can stay in physics long enough to puruse a phd. also how viable is it to work in other fields after bachelor or masters.

[limber thunder]

have you checked QS rankings

https://www.topuniversities.com/university-subject-rankings/physics-astronomy

these (e: and rankings like these, more generally) are reliable to get a rough idea but a lot of factors come into calculating the position, e.g. research, infrastructure

so, some universities may not have a very good UG program but put a lot of resources into research or something

[restive magnet]

thank you

ill have a look

[haughty quest]

oh my god XD

[fervent pebble]

the whole conversation is great if u feel like taking a look

[haughty quest]

just did XD

[hexed pier]

Yeah, I wasn’t thinking straight. Funny how I try to say dumb things to be funny but say something even dumber in earnest

[vast wraith]

modal logic?

[fervent pebble]

gods, i don't even know

[neat lintel]

I think you better talk with ppl in the industry of physics they would give you more precise info because they probably were in your shoes so check the physics server, you will find it in here #old-network but I guess physics with master's and programming could get you so far but try a PhD if you get a chance

[ember lance]

Got a mint plant at a gardening fair

[minor totem]

Is anyone good at r^2 functions

[ember lance]

Its name is Arbolito

[limber thunder]

yay mint plants are cool

I have a bunch at home

[minor totem]

Please someone just help me

[static loom]

did you make a question channel

[minor totem]

It’s science

I can’t

Well “science”

Plus I don’t really make those cause 90% of the time it’s just someone going into to just rotate the image

I want to get the data for total number of students get a degree in management, marketing, accounting, finance to do some analysis. anyone know where I can get this data? I was only able to find number of student in business (general and not in specific field). please, if anyone know anything about this plz lmk

[limber thunder]

depends on the geographical location and the specific variable you want to study, which I'm assuming is # of people picking a specific major within a given cohort

either way maybe Kaggle datasets are a good starting point https://www.kaggle.com/datasets?search=graduates

[neat lintel]

Hello

[past pecan]

what the f(x)

[lime cedar]

thank you!!!!!!!

[next dawn]

guys am i cooked if i have a 4 from maths but i have major test next week and i know almost everything but i always choke on exams?

[vapid zealot]

hi

[north topaz]

are you doing (I)GCSE

[next dawn]

no im in my first year of high school

but i have igcse book

wait no i am doing (I)GCSE

im dumb sorry

[north topaz]

ok ok

that's weird, how do you have a 4 from maths if you know almost everything?

[severe harbor]

hi anyone know where to start learning math for competitive programming? Like discrete math, linear algebra, combinatorics, etc. I'm not terrible just hitting a plateau

[next dawn]

its on a scale from 1-6 and i have a 4.7 becasue we had a qt on the second day of skl and i was lost

[north topaz]

oh that's not bad at all

I was assuming 1 to 9

[next dawn]

oh- alr

[neat lintel]

How is iGCSE on a scale of 1-6 🫥

Isn’t it 9-1

Or A*- U

[north topaz]

local grading for IGCSE, cause their school ig

[neat lintel]

👍

Ours did percentages for in-school grading

so we have a different grading scale

[old oak]

5.5 or bust

[heavy bridge]

yall are smart right

[glass peak]

Less convinced of that every day

[static loom]

clenching in preparation for 2+2= question

[glass peak]

getting my calc (short for calculator) ready

[hidden isle]

@ helpers what’s 1+1

[iron bramble]

#- rr

-# 44

[vast wraith]

optimistically waiting for the day i’ll see this interaction:
> what’s 1+1
> 2
> thanks

and they lived happily ever after

[hidden isle]

impossible any new account to the server that asks what 1+1 is immediately gets sent to the underworld

[neat lintel]

You're bloody damn right lol

There are a lot to learn in that world

[velvet sun]

Hi, I just joined to do a simple question. Are the khan academy math courses good? can i rely on them to help me understand calculus and algebra concepts? or should i use other (maybe better) tools?

[neat lintel]

Yep, they are good if you like videos and so lots of questions

Books and notes are the best methods for learning maths

But maybe khan academy contains only what you need

You gotta check it out

[fresh comet]

hello, and welcome to mathcord!

yes! KA has lots and lots of good practice problems, and doing them will certainly make you better at algebra and calculus.

with that said, it doesn't have to be your only resource! you can also check out sources like the Ognanic Chemistry Tutor on youtube, Paul's Online Notes, or just any old algebra/calculus textbook

the most important thing is that you do lots and lots of practice! that's the only way you'll find yourself improving at math

[velvet sun]

Thanks for answering!

And for the books, any page / book recommendations for these subjects?

[fresh comet]

late response, but I don't believe I'd be the best person to ask for that, haha

I wish you the best of luck with your mathematics journey though! ❤️

[burnt dune]

yes they are

they are very good

iirc on the website they have exercises as well

i think up till calc1-2-3 and linear algebra they are pretty good

assuming these are the more "cs-engineering" courses

rather than analysis and proof-based linear algebra

[neat lintel]

Nah but IGCSE is usually uniform around the world

Your final exams would still be 9-1 or A*-U if you are doing iGCSE

[sharp oar]

This is not related to math but :

Can a person i blocked in discord still see my chats in this discord server ? Or they won’t ?

It’s my first time blocking someone on discord so I don’t know about this 😭

[wooden stag]

Whom did you blocked?

[agile fiber]

if you block someone then you won't see their messages, but they can still see yours

[boreal whale]

I mean that’s kinda private innit

[wooden stag]

Yeah maybe

[brazen mulch]

they can also choose to see their messages anyway 😎

[gritty crater]

That doesn't seem fair

I always thought that if you block someone, they won't see your message and you won't see their either

[static loom]

interesting, why

[midnight vessel]

They also can't add reactions under your messages and see your "About me"

[midnight vessel]

They will, unless they block you too. I always thought about it like "I don't want this person to interact with me anymore, block"

[gritty crater]

To me it means even if you block them, they can still stalk you

[sharp oar]

I thought he’s friendly at first because he sent me a friend request here on discord , so I thought he wants to be friends or acquaintances at least lol

But when he asked me about how I treat my online friends, I told him that I don’t videocall with them (I’m very shy and I don’t think I need to videocall ppl for them to stay friends with me . My online friends don’t videocall with me either ‘cause they aren’t always online and most of my friends have strict parents) and then he said “Sorry then I only make real friends” and then he unfriended me after 🗿 I find it weird

[fervent hatch]

I live in an apartment.The rent is 11000 dollars.I have a roommate and we split the price by paying 5500 5500.This month,landlord said he needs us to pay for his business.He said cut it from rent price.My friend paid for his business 1350 dollars.Now the rent is due and I don't know who should pay how much

[lost spruce]

rent is 11k??? where the fuck do you live

[solid snow]

have him pay 5500 - 1350

[lost spruce]

new york 😭

[solid snow]

and then you pay the same amount

[fervent hatch]

Naah we're in turkey i tried to add context to make it interesting

11k turkish kebab lira

[fervent hatch]

Ye that's what also chatgpt says but aren't we supposed to pay 9650 in total

[severe harbor]

oh so he paid it early

then isnt it obvious

u pay the same amount as usual

[limber thunder]

what I dont understand is what you mean by "landlord said he needs us to pay for his business"

[fervent hatch]

No he only paid 1350

[severe harbor]

he pays usual -1350

[lost spruce]

oh thank god i was about to cry

[solid snow]

this is what 5500 + 5500 - 1350 is

which is still the payment scheme

[fervent hatch]

Yeah he needs to pay for the apartments wage

But he's abroad

So he wanted us to pay for us

[coarse bridge]

[fervent hatch]

and cut it from rent

[severe harbor]

😹 this wouldve been so much simpler without that statement

[gritty crater]

You pay 5500 and your roommate pay 5500 - 1350

[fervent hatch]

Thank u sir that made sense

finallyyyyy

[solid snow]

literally what i said

[severe harbor]

😨 im scared for this guy

how could he not subtract

on his own

[fervent hatch]

I was doing it like 11000-1350 %2 cut the 1350 from my roommate he pays 3475 I pay 6150 and I freaked out

[severe harbor]

😭 wtf

he subtracted after dividing 11000-1350 by 2

[fervent hatch]

im dumb as hell bro :/

[gritty crater]

what does 1350%2 even mean? 1350 mod 2?

[limber thunder]

÷

[fervent hatch]

Noo i typed it wrong 11000-1350 / 9650/2 4825 cut the price my roomate paid 4825-1350= 3475 and 6175 is left for me to pay

i couldn't find where did I do wrong in here

[severe harbor]

bro is a professional overengineer

[severe harbor]

u did wrong by dividing by 2 after subtracting

i mean u kinda subtracted twice too

[fervent hatch]

Why tho??

[severe harbor]

ur total rent is 11000

ur roommate's rent is 5500

he paid some of his rent early

so subtract that from 5500

5500-1350 is what he pays

ur rent is not impacted

[fervent hatch]

Nooo

Wait are you going based off the story or

to make it simple for me

[severe harbor]

i only had the story to go off of

[fervent hatch]

because in the story he didn't pay the rent he paid for the landlord's personal thing

and he said cut the 1350 from this month's rent

[severe harbor]

ok and isnt 5500-1350 "cutting" it

[fervent hatch]

Yeaah

Ohh I substracted it twiceee

If we would have paid together both of us would be paying 4825

righttt

[severe harbor]

yes but only he paid the 1350

[fervent hatch]

Now I get itt

Yeah thanks man

I mean it wasn't even that hard but i overcomplicated it smh
