Subnautica is one of my favorite games ever

I learned to scuba dive because of it

If you are planning on getting it, don't read anything about it.

Or give yourself amnesia somehow before playing it.

Subnautica can have my wallet

[ember lance]

It's coming out in 2025 for early release, and I think there are plans for it to last 2 years before full release.

It is going to have multiplayer.

You are one of the good ones! Er. He answers in a foreign speak. Modulo? Sounds advanced. I only know arithmetic pretty much. I mean I'm joking, but not really...Haha, thanks! I like edits, else it is just too spammy. This would have been 20 messages! Then the math deities would have banned me! This is addition! I have mastered it! I like syrup, by the way. Just saying. Bit off topic, but still. Important. I use simple math to count supply lines. I was also counting peanuts. But I ate both, so now I have ZERO. I guess I won't be getting any awards about that. Haha.

[latent violet]

I want to be good at math, but i dont know where to start or how to... How would you guys approach this problem?

Im tryna start with studying conic section and stuff.... But as I study it, it seems to be launching all sorts of equations and stuff that i can even visualize yet understand their meaning and how they work

And now im feeling quite troubled upon how does "(x - h)^2 + (y - k)^2 = r^2" even make up a circle

I cant visualize. Sure, i can solve some given equation and turning it into a standard form of a circle, but i never understood deep inside what it means

But im lost of ways to be able to know it

Ive searched on reddit, quora and such, but it seems to not relate to my own story, where im rolling my eyes still thinking how that equation turns into a circle

How would u approach it then, if i may ask

Dam.

[north topaz]

ah do you know how the distance formula works?

it's basically just Pythagoras

[latent violet]

Yess, its like a way to know the displacement, no?

But then, how does it become a circle

Does it rotates?

[north topaz]

try reading this

[latent violet]

Like as the x moves, does the point circles around the center?

[north topaz]

yes, and there are some advantages to thinking about a circle in terms of that

in terms of an angle

but, for this question

you should use the definition of the circle:

all the points that are r units away from another point (which will be the centre)

[latent violet]

SO ITS TRUEEE???

That as x grows, itll go and just circle around the center?

Based on the equation of a circle?

But..... How?....

[ember lance]

Try plotting points.

[latent violet]

Btw, another problem i have is that, why is x and y in the same side of an equation?

Arent they supposed to be opposite of sides?

[ember lance]

Also, what is your motivation for learning this?

[latent violet]

Just out of curiosity ig

As i said, i just want to be good at math

Hence, understanding how it works

[ember lance]

It helps if you have a concrete goal in mind.

[north topaz]

this is the definition remember

like a circle is just all the points that satisfy this condition

you don't need a point to go around the circle

[north topaz]

ah you've never seen anything like this

[ember lance]

Math is such a big field, that if you aren't going to use conics, your time might be better spent in some other areas. Unless you have some other motivation for it.

[latent violet]

I wanna know the reason for the equation(?)

[north topaz]

yes up until now you've only seen $y = mx + c$ or $y = a(x + h)^2 + k$ or $y = ax^2 + bx + c$ right

[fathom swallow]

southlander!

[north topaz]

it is a bit weird, but it makes perfect sense

based on Pythagoras

d is the radius btw

[latent violet]

Yess, im only used to that kind of equation

Im quite puzzled how does an equation where x and y is both at one side works

[north topaz]

the problem with trying to rearrange the circle equation to get y on one side and x on the other

is that you can do it, it's going to be $y = \sqrt{r^2 - (x - h)^2} + k$

[fathom swallow]

southlander!

[north topaz]

but that only gives you the top half of the circle

the bottom half of the circle is $y = -\sqrt{r^2 - (x - h)^2} + k$

[fathom swallow]

southlander!

[latent violet]

Oh wow

So thats the real definition of how to draw the circle

(?)

[north topaz]

so we should start talking about functions and how they relate to their graphs

a circle is not a function

a function needs to pass the vertical line test

one x-value ------> one y-value always

[north topaz]

a circle is a relation

[north topaz]

there are many many definitions of a circle

we choose different definitions depending on which one is more useful for our problem

[latent violet]

@north topaz , let me get this straight, circle is not a function, no?

[north topaz]

nope

that's correct

[latent violet]

Oh.

So whats the purpose of this equation then

[north topaz]

I was answering your question about "why can't we just bring y to one side"

[latent violet]

.

[north topaz]

yeah I mean just keep reading this until it makes sense

or watch a YT video or something

[latent violet]

But we actually can, yes?

[north topaz]

yes, but you need to break the circle in half

[latent violet]

Godd thankyouu, i think im slowly getting it now

[latent violet]

Btw, so in that way? I can be able to fully comprehend the equation then?

[north topaz]

yes just do this actually

and come back to the image when you are ready

[north topaz]

until you've convinced yourself

that you know why $d^2 = (x_2 - x_1)^2 + (y_2 - y_1)^2$

[fathom swallow]

southlander!

[north topaz]

after that we just need to change the variables to match

so d is the radius, d = r

$(x_1, y_1) = (h, k)$ and $(x_2, y_2) = (x, y)$

[fathom swallow]

southlander!

[latent violet]

So the equation isnt really about a function, or technically, its just not a function?

[north topaz]

so $(x, y)$ is free to move around the circle

[fathom swallow]

southlander!

[north topaz]

nope, it's about a relation

x and y are related, but they do not describe a function

cause it fails the vertical line test

[latent violet]

Whow..

Thanks mann

[north topaz]

no worries!

[north topaz]

[ember lance]

Depends on your country. USA forces students to take English writing classes.

[limber thunder]

I think communicating and writing is an important part of mathematics practice either way

how that's implemented will depend on each uni's program

[daring parrot]

should i like travel abroad then

[limber thunder]

but I for one would expect a math major to write proofs and maybe short reports of sorts at a bare minimum

[ember lance]

Hmmm, that seems excessive to avoid writing well.

However, I believe some other countries have better ug programs in maths. But as derivada said, you should aim to write well.

For me it was 2 English writing classes. I also didn't enjoy taking them, but I learned some interesting things.

[limber thunder]

yeah honestly I don't think an entire English class is necessary

instead good writing practices should be taught throughout but thats a bit idealistic

[ember lance]

I think it's because "international students" is part of the business model for many universities in English speaking countries, and a lot of them us don't speak/write English well at all.

[limber thunder]

could be a factor yes

but even then I'd rather take gen eds

[ember lance]

I mean you are also forced to take gen eds lmao

[pulsar pagoda]

Gen eds should be thaught at highschool

[limber thunder]

no I think there's some point to having those in university -- wider variety of topics and since you're an adult by then you're in a better position to engage with them

well theoretically

school is about getting the fundamentals down

[ember lance]

I've also heard it helps subsidize less popular majors

But that could be an urban legend

[pulsar pagoda]

Neither school nor uni get the fundamentals right sometime

I know from experience

[limber thunder]

normally the dept. giving the course gets some money associated to the cost x student of teaching it yes

idk the specifics in e.g. the US but that's how it works in most places here

[sharp mulch]

[bright night]

but I decided to try anyways, and I found via chatgpt that the average density of every element in the periodic table (covering everything discovered my mankind) in in^3/lbs to 2 decimal places is 6127.07, and I tried cubed root and cubing it but the answer still didn't make sense, coming out with 18.57 and 229,160,570,635.63 respectively and somehow this makes me think there might be some sort of answer but i know I am just wasting my time

[bright night]

0.5

[sharp mulch]

density is not in units of in^3/lbs

Density would be lbs/in^3

And the average density of every element up to 118 is not 6127.07 lbs/in^3, it's 0.353 lb/in^3

[neat lintel]

Can someone advice me on smth

[upbeat heart]

Guys, why everytime I study I feel like not squeezing my brain enough. It's like I'm only asserting 60% of my brain power?

[north topaz]

The way I see it, doing well in Math, Physics or Chem has 3 tiers:
knowledge, understanding and application

Knowledge can be enhanced by simply studying and revising a lot, depending on your necessity and capacity. Understanding can be enhanced by asking yourself "do I really understand this?" and trying to explain a concept from a fundamental level, and then asking your teacher or watching a video (etc) to find an explanation. This is beyond only what is the textbook. A lot of times you may not cover things in class or in the TB that will be useful to you, so expand your knowledge beyond them when required.
Application requires you to 1) understand the topic, as then you will be able to know how to apply it 2) enhance your problem solving, such as by devising techniques to solve the problems such as https://www.nwtutoring.com/2022/12/10/how-to-solve-almost-any-physics-problem/ 3) Practice. You can practice topic questions on websites such as pestle https://pestle-ib.firebaseapp.com/ (which is free) or others.

Another important part is reflection. Reflect on where you're going wrong. What kind of questions are you going wrong in? Why are you going wrong in them? Is it because you're lacking knowledge? Because you didn't understand the concept? because you're unable to apply the concepts? Then, improve on that aspect by adopting a suitable strategy (as I mentioned above). I'd also suggest that you do a little bit of studying/practice everyday so you get into a habit of it, and will not have to grind in the last few months.

Yes, Calculus is highschool

gpt 3.5 days

[ember lance]

It can do graduate level math sometimes

[near mango]

i mean it cant do proofs but it can unreliably do computational stuff

[hardy iron]

But can it do them correctly?

[ember lance]

sometimes

[shut birch]

ima just send in dms

[hardy iron]

Seeing it ‘compute’ large numbers is #funny

[near mango]

actually it probablt can unreliably do proofs too

[hardy iron]

Then you’re violating the #rules

[hardy iron]

Some proofs of it are just so funny

[ember lance]

And a lot of the time for me it's somewhat easy to fix the arguments.

[hardy iron]

There’s this neat trick of pasting questions into ChatGPT and ask your students or peers what step did it go wrong

Sometimes it’s obvious, sometimes it’s less obvious

[near mango]

yes we did that in our proofs class

[shut birch]

im talking about how its saying it makes up stuff blah blah. Hallucinations will be daam near zero by next probably. Already low on o1.

[hardy iron]

Do you even know how GPTs work?

and how math works?

[shut birch]

yeah obviously.

[hardy iron]

Then you’d know that it just generates text that sounds correct or human like

[shut birch]

Why are you asking that? You think hallucinations are inherent?

[hardy iron]

While mathematics rely on precise logical stuff and such LLMs cannot reason

[near mango]

what if its just regurgitating some answer from online

[shut birch]

Irrelevant. If it can do a problem it has never seen before, even if its on patter recognition, and solves it correctly, just like a human, NOBODY cares that its generating text that sounds like humans.

[hardy iron]

Wrong, it can’t “solve” it correctly because it can’t reason

[hardy iron]

#serious-discussion message

[hardy iron]

That too for famous coding problems and famous textbook problems

[shut birch]

what? obviously it can reason. artificial reasoning is what I would call it. How is it that I can make up a puzzle right now, about anything, and it will solve it correctly even if its never seen it in its database? Pattern recognition? Well humans do that too right?

[upbeat heart]

Is there any bot that can have me teached with?

[hardy iron]

There’s no built it reasoning module, all of its reasons are just prediction of the next tokens

[near mango]

thats just being pedantic dude. its just unreliable, simple as that

[hardy iron]

No, read the bot’s advices again

For learning resources I’d recommend Khan academy or other YouTube videos

[upbeat heart]

Isee thanks

[hardy iron]

Just doing more than 10% of the questions wrong makes it unusable

Nobody is going to accept GPT-written proofs because of its inaccuracy

[near mango]

for something that has a given answer, i think thats pretty usable. im not defending using chat gpt for proofs or anything

[shut birch]

Sure, but does it think step by step trough a problem? Im not talking about 4o, just o1 specifically? Like is it thinking about its previous tokens?

Just predicting. How can it write a story without using a specific letter i asked for? This was previously impossible. How does it know know how many r's are in strawberry? It doesnt have much more training data, 4o still gets this wrong to this day, even tho o1 is just 4o, according to open ai, with reasoning abilities

[hardy iron]

o1’s “think step by step” bullshit is just it feeding itself relevant tokens for more of its answers

There’s no actual thinking or logical reasoning unlike those theorem proving languages like lean

You’re yet another victim viewing models at face value

Anyways, refer to this.

Read the last sentence

[shut birch]

It outperforms experts, at least in tests for now, are you aware of that? In things like physics, chemistry, and biology. You can call it whatever you want but its obviously working, and its OBVIOUSLY going to surpass you, and me, shortly.

[shut birch]

Like have you seen the jump from 4o to o1? Its huge

[hardy iron]

it outperforms expert
I doubt so, tests metrics are irrelevant against real-world research and papers publications

[hardy iron]

[hardy iron]

Yeah, it’s just bullshit in those field, specifically

[shut birch]

Also what was the answer to that problem you sent me earlier?

[hardy iron]

I’d admit it’s pretty decent at coding though

Try making o1 rewrite a whole 2500+ lines typescript API file then maybe we can talk

[shut birch]

also sam has already hinted at 4.5 (or whatever else they release or demo in the 12 days) being better then o1. Someone said they had hit a wall and he replied saying "this is only the first day of the 12 days" hahaha

[shut birch]

Genuine question. Do you think 4.5 (or whatever its called) wont be able to write 2500 lines of code? Do you belive this?

[shut birch]

actually I wanna try that. even tho i think it will fail

[hardy iron]

What the fuck is 4.5

It’s not released yet

[shut birch]

Give me the 2500 lines of typescript API file you want to rewrite

[hardy iron]

Why would I share my private codebase for Xnafu, wtf

[shut birch]

you think ima hack you with o1 or what?

[hardy iron]

Anyways, just refer to !nogpt

[hardy iron]

Do you have any idea how developing web app works?

[shut birch]

Do you think when 4.5 is released, it wont be able to write 2500 lines of code? Do you belive this?

[shut birch]

Yes. o1 taught me actually

[hardy iron]

[hardy iron]

Actual slop

Posting AI generated answers to help questions is also against the rules so

[shut birch]

[hardy iron]

¯_(ツ)_/¯

[shut birch]

Its just a question

[shut birch]

Do you think 4.5 will be able to write 2500 lines of code on release?

[hardy iron]

But yeah it won’t (as in without enough consistency)

[shut birch]

fool

[shut birch]

You are a fool

[hardy iron]

Even if it can, then I doubt 4.5 can rewrite the manyland.js @boreal sun (manyland reference)

[hardy iron]

Now you’re resorting to insulting people for no reason

[shut birch]

mmm lets see how much o1 can write right now

[hardy iron]

So yeah I kind of won this argument

[shut birch]

what part exactly?

[hardy iron]

You called me a ‘fool’

You have no actual expertise on anything and you just rely on AIs

[shut birch]

true yes. And what part of the argument did you win with that? Makes me exactly 0% wrong or right about anything

[hardy iron]

You lost the argument by failing to use logical reasoning and instead resorted to insults

Wait I have some things I wanna do

You lost, Q.E.D.

Yeah this is cool as fuck

[near mango]

lmao

[shut birch]

I did use logical reasoning, maybe i was about to after calling you a fool. But now I dont want to

[hardy iron]

Yeah I forgot a . at first

[near mango]

you lost, ⬛

[hardy iron]

Explain the logical reasoning in this then #serious-discussion message

[shut birch]

no you fool

[near mango]

thats a pretty funny mathy thing to do ngl

i want to do that to someone

[hardy iron]

Yeah

I’ve always wanted to do this but they either leave the server or block me

or they just apologized

But yeah, moral of the story, TLDR or whatever kids these days call it

Don’t use GPTs to help people

[near mango]

i want to go

theorem: if you are cringe, i am based.
proof: suppose i am not based and you are cringe. this is a contradiction because i must be based, it is inherent to my being. therefore, if you are cringe, i am based. Q.E.D.

[shut birch]

basically its pretty simple. If you think it wont be able to write 2500 lines of code, then it would mean progress has slowed down drastically, and the jump wont be as big as from 3.5 to 4o. However, this is obviously not going to be the case. More money then ever, power, expertise, plus others like at google where they said 100x or someting crazy like that.

[hardy iron]

So you’re daydreaming?

[shut birch]

Also the amount of development into 4.5, longest to come out, with again, more power and everything I said.

[shut birch]

Im just pointing out the obvious logical conclusion. I could have said the exact same thing about 4 before it came out after 3.5

[shut birch]

Plus we can already see the massive bumps. I mean o1 is literally 4o, in open ai emails they sent out to people its literally called 4o with reasoning hahahah

You are fucked when 4.5 comes out hahaha. Well its likely it will be previewed on these 12 days since it was on the teams account as preview then removed

[hardy iron]

I’ll let you cook then ig?

[shut birch]

what?

[hardy iron]

Just don’t burn the food

[shut birch]

If im proven wrong and 4.5 cant write 2500 lines of code then i will admit utter and absolute defeat and will leave society. But im like 99% sure it will, obviously it will

[hardy iron]

It can but without a good enough consistency

[shut birch]

Obviously

[shut birch]

with good consitency

[hardy iron]

Duh

Nah I’d win

Do you want to gamble on this?

[shut birch]

Obviously with good consistency

[shut birch]

NO. You wont pay, obviously

[hardy iron]

A hand? or an arm?

[shut birch]

mmm, maybe my testicle

[hardy iron]

Deal!

[near mango]

i look away for 2 seconds and now you guys are trading your genetalia what happened 😭

[hardy iron]

It’s a masterful gambit

[shut birch]

I wont forget. I'll come back when 4.5 is out to prove how you were obviously wrong

[hardy iron]

Sure !

[ember lance]

For reference, I also asked o1 the L.I. question and it gave me a correct proof (of the half I asked because I forgot to write iff instead of if).

[hardy iron]

Yeah since forward is pretty obvious

I left my book about partial ordering at my dorm 😭

[ember lance]

Okay I asked it for the converse and it also gave me a correct proof, and much clearer than what I usually check for in here.

[shut birch]

the only thing that is really annoying is the message limit. is it still 50 a week? i hope they make it at least 50 a day soon

[ember lance]

Yeah, that's why I didn't want to ask it for the converse. I assumed it would get it right. But I asked just in case.

[fervent flame]

iuzu is delusional and catgod is at worst in denial and at best best disingenuous. obviously o1 can do ug level math problems, but cot isn't really thinking as we do it

[shut birch]

obviously its not thinking as we do. thats why earlier I called it artificial "reasoning"

[shut birch]

It processes each part of the problem individually rather then just jumping to the conclusion. It breaks down the problem, like a human would.

[ember lance]

Anyways, I think both of you had something to teach each other, but were busy "winning the argument".

The most important thing is that using chatgpt to solve someone else's questions is against the rules. If it gets the question wrong, you are not only hurting yourself, you are hurting someone else with a bad explanation.

[shut birch]

No one who uses chat gpt to answer questions here will make it obvious they use chat gpt hahaha

[ember lance]

Literally saw someone get banned for that this morning.

[shut birch]

MMMM. Lets say its an... 11th grade highschool question, a question where o1 will obviously get it correct, (unless you can give me an 11th grade math problem o1 fails) and they give the answer (without saying its chat gpt) and it does actually help them?

[ember lance]

The point is, let someone that knows about the subject answer the question, regardless of if you can fool people into thinking you are not using chatgpt.

I think the danger of misinforming someone is much greater than letting a question go unanswered for a while. They can ask again at a latter point too.

[shut birch]

What if you 100% have the correct answer even if chat GPT gave it to you? What’s wrong with not telling them it’s from Chat GPT when you know it’s correct anyway?

[ember lance]

This is a rule edge case, and I don't want to comment on it. Ask ModMail I guess.

[visual topaz]

What's wrong is that this is called academic dishonesty.
Perhaps ignore all the bullshit about copyright, which protects capitalist interests, and look into what is the spirit of honesty

[hidden siren]

Hi

[raven plaza]

If you know it's correct then sure, but people who pull out chatgpt tend to not know

(but why ask gpt when you have to verify its answer anyway)

[soft aspen]

You didn’t do the work and even if you know it’s correct you’re not showing that you know how to do it’s, which turns into a problem where you say you know how to do it but since you never did it yourself anyways you can’t prove you know how to do it

Strange paradox

[brittle socket]

Damn you absolutely whaled on him. Dare I say: fishwhaled on him.

[candid veldt]

is there an example of a set that we know to be nonempty, without being able to construct an element of it? (obv you can construct that trivially with the set of irrational numbers x such that x^x is rational or a similar thing, I'm talking about an actual useful that one naturally comes across)

[surreal sapphire]

there are plenty of things where we know solutions exist but we cant construct them explicitly

[raven plaza]

Let f: A → B be a surjection and let S be the set of all g: B → A such that fg = id_B

[surreal sapphire]

say solutions to some PDE/ODE

[raven plaza]

In general you need axiom of choice to show S is nonempty

[surreal sapphire]

you often prove existence/uniqueness but actually constructing solutions is not possible

this is essentially the same problem you stated (most real numbers cannot be finitely described), but it comes up naturally

[sharp mulch]

Set of noncomputable numbers

It also depends a bit on what you mean by compute

[candid veldt]

yeah, that's what the second part of my sentence is for, ofc you can shove objects you cant construct explicitely, I meant something that you encounter in the form of a set

naturally

[candid veldt]

yeah that makes sense

some solutions to optimisation problems as well I suppose

[sharp mulch]

For most of these differential equation solutions, we can approximate them arbitrarily well

[candid veldt]

I kind of meant a more "classical object"

as in a set that comes up a lot, is nonempty, but where we have no idea of what its objects look like

[sharp mulch]

Normal numbers

Well it depends on what you mean by comes up a lot

A lot of these non constructive sets are hard to reason about because they are non constructive

[candid veldt]

oh I totally forgot about those

[candid veldt]

yeah I admit that part of my question is up to interpretation idk myself

[safe parcel]

What math topics I need to be good at?
For CS, AI, Ml & Robotics
I would be grateful if you would give me best available resources for those topics as well

[river moon]

you don't need university level of math to do CS or robotics

[limber thunder]

depends on what exactly do you mean by "do" CS or robotics, I think robotics in particular certainly uses notions of 3D geometry, control theory and statistics

AI and ML on the theoretical side of things is statistical inference basically

so for any of these I would say a standard undergrad math curriculum including calculus, linear algebra and statistics would be good

Hello guys

[sharp oar]

hi!

[still shuttle]

is rereading a chapter 3 times+ frowned upon here? not for the sake of thoroughly completing exercises - but rather fully grasping the contents of what’s being discussed

i feel like i’m reading slower than others would but at the same time i think the breadth of what i’m getting from the book is a lot deeper

[sharp mulch]

No it isn’t

[cinder zephyr]

I read over the same 4 pages like 10 times today

so no

[true zinc]

Absolutely not

[daring parrot]

thinking of pursuing math degree, but gen eds and language arts english classes too hard for me

what should i do with my life then, i suck at writing and communicating i have cognitive delay
only passion i had in school was math

[ember lance]

Did you write this yourself? If so, I think your English skills are sufficient to get you through college.

You communicated your idea clearly. Usually colleges have writing centers that will help you correct your writing.

[brittle socket]

One idea that might be of use is to try to write cleanly in everyday writing.

So, read your messages/emails/etc a couple of times before sending them; edit them if you find any parts that could be further polished.

That might help you get a habit of writing clearly, and you might also see where you fall short.

[brazen mulch]

Is it, at all, possible to find parts to further polish? Sometimes, some writing just looks wrong but feels impossible to rewrite.

[glass peak]

There’s a strict 2 pass rule if you ever want to be respected as a mathematician unfortunately

[raven plaza]

Simply git gud

[brazen mulch]

your butt can't even spell 💀💀

[feral dragon]

in an LLM, or any machine learning algo, is any thought put into the size of the matrices they use? LIke the specific n for the nxn matrices? I know in general it seems like they just want "more power" and more GPUs and bigger matrices, but has any research been done on how the output changes by changing nxn to (n-1)x(n-1) or picking closest prime or closest power of 2 to n?

[river moon]

the size of the matrix is a consequence of a number of neurons and connections

which has been studied a ton

[faint light]

gen ed is so cringe

hi welcome to my server

[obtuse idol]

can you all add me on here I want my friend requests to go up..?

[proven oar]

Hey there! As it doesn't concern maths directly, I'll ask in here: is somebody familiar with GeoGebra's JavaScript-API, and knows whether there's an existing typescript definition of said API? Couldn't find anything yet, and having intellisense working could help getting off the ground quicker.

[ember lance]

You can also try #computing-software and https://discord.com/channels/268882317391429632/1213610885277421588 but your situation is pretty niche so probably asking the GeoGebra community will be more helpful.

[proven oar]

Okay, I see - thank you! After a few experiments, I noticed how I only really need a hand full of methods, so I think I'm okay with simply keeping it on the level of JS. In any event, do you happen to know whether there's a GeoGebra Discord or forum I could pay a visit?

heres a cool lil joke for you guys

in 30 years our "live laugh love" will be "deny defend depose"

[brazen mulch]

disqualify, dislocate & dissolve yourself

[ionic star]

that's stupid

like, 30 years is too long

this joke should be "in 6 months"

and most jokes of this format shouldn;t be "30 years"

[brazen mulch]

the joke has been dismantled, dismembered and disinfected

[subtle lynx]

Someone teach me maths please

[twin granite]

What part?

[subtle lynx]

Any 🥴

[twin granite]

Okay. Do you know what a number is?

[subtle lynx]

Im doing statistics atm

[twin granite]

Ah, sorry, I don't know statistics. Though if it helps, maybe you could specify that you are looking for statistics help the next time you ask someone?

It might assist you in getting clearer answers.

[old oak]

I don't!

[twin granite]

That's alright, neither do I!

[civic fog]

Hi Goku

[subtle lynx]

Hi

[twin granite]

The best answer I can come up with is that a number is a general kind of reality-portion cut-distingishment.

[old oak]

Appealing but lacks rigour

[tame harness]

hi guys does anyone know where to ask calculator help questions? or should i even ask them in this server

[north topaz]

(btw, answered in help channel)

[twin granite]

Just a second, I pressed enter by accident before I could finish.

[glass peak]

I think this is sort of the idea of a schema that’s talked about a lot in psychology and pedagogy

The issue there is that they’re malleable and personal, defining a number kinds suffers from this issue imo

You can have your own notion of a number, we all kinda know it when we see it, but pinning down a specific universal definition I think will always be impossible because it’s just too broad

But equally I don’t think this overly matters, for objects, as you put it, I think “you know it when you see it” is kinda good enough

[old oak]

I was mostly alluding to the fact that there is no commonly-accepted definition of the word "number" in mathematics. We have perfectly fine rigorous definitions of phrases such as "natural number", "real number" or "cardinal number", but no definition of just "number".

[arctic jacinth]

hi guys im new here btw, im in grade 9,
do u guys have any tips for Quadratic Equations, like any tips to not make any mistakes, i make few in the fraction type of Quadratic equations
If anyone has any tip pls tell me

[north topaz]

what sort of mistakes?

[keen lodge]

hep me understand index sets

well give me a sec ill type

why cant i paste a image??

why and how tan theta changes to cot theta?

hey

could anyone help me with fouries continuous series and transforms?

how to get started with maths..though it's not my cup of tea i just want to pass my exams ..if i like i will continue further more

which grade?

[blissful glen]

Ik I didn't ask it, but I have similar thing. I'm 1st grade of high school in Poland.

[trail wagon]

Well... Lets start with formulas

Gimme a formula to break it down for you

[ornate bloom]

Hey guys

[narrow carbon]

Hi

[ornate bloom]

I did my AP calc mock today, the FRQ section

Is 27/54 good?

I fear that I may have bombed

[true wedge]

is it calc AB or is it BC

[ornate bloom]

AB i think

[true wedge]

you bombed

[ornate bloom]

If memory serves me

[ornate bloom]

Ah

What a shame

[true wedge]

are there taylor series

[ornate bloom]

I may still recover in the multiple choice section

[ornate bloom]

What is a taylor series?

[true wedge]

Ok it's AB

yeah clutch up in multiple choice

or practice frq more ig

[ornate bloom]

Almost certainly needed

My teacher always says this class will need more studying than any of us have done before and yet I still chose not to study

Whatever the case, thank you

[true wedge]

Calc AB should be reasonable difficulty to study for

BC is much harder

[ornate bloom]

I see

[true wedge]

but on the other hand 27/54 would probably be enough for a decently high score on BC lol

[ornate bloom]

Lmao

Even half the marks is still decent in BC? Must be a hard test lol

[true wedge]

i think it's like around 60% counts as a 5, changes year by year

[ornate bloom]

I see

[languid lagoon]

I have a calc final in 4 hours and i cannot bring myself to give a fuck

Probably not going to do that well anyways so

Ughhh i hate to sound so self pitying but this semester went so poorly 😭

I miss studying linear algebra

I wasnt much good at it but i really did like it, same with analysis

I was soooooo shit at analysis but i loved it a lot
