[loud snow]

Is it called explosion?

Thats cool name and it makes sense

[alpine comet]

yes, that's very true

and they are not hesitant to fire you based on performance. There's always some genius waiting to be hired

it depends. I heard that hardware engineers, dealing with FPGA and whatnot, actually get paid an insane amount

because it's actually hard to come across good experts in that area, compared to software or math models

[jolly junco]

Googled what that is but it seems even the guys over there struggle to explain it very simply

From what I've understood it's a configurable circuit designed to perform a task out of a specific set of processes?

(Very poor analogy) Like a computer where you can't add new programs?

[jagged forge]

fpga = field programmable gate array, from what i understand it's like you can reprogram the circuits themselves

they're not as fast as ASICs (application-specific integrated circuits) which are set in stone once you manufacture them

but they're a lot faster than cpus

usually in an area like finance you have an fpga network card which is doing processing on incoming packets as fast and as early as possible

since you're getting market data over the network

[jolly junco]

An ASIC would essentially be a circuit only designed for a specific piece of code, right? Like a ROM chip?

[jagged forge]

i'm not sure what a rom chip is but yeah, asics are usually special purpose

[jolly junco]

Sorry, the BIOS chip

[jagged forge]

some of the fancier enterprise network cards have asics for common tasks in the data center like compression and packet filtering

so they can read data off the network and compress it at line rate (up to 400 gigabits/second)

for the top of the line cards anyway

400 gigabits is so stupidly fast and you can put like 8 of those cards in one server

[jolly junco]

Makes sense, that isn't gonna do anything else so you might as well optimize the shit out of it

[jagged forge]

right

for these cloud companies, they spend a considerable amount of resources just shoveling data around and decompressing it from storage

so it makes sense to optimize that

[jolly junco]

So an FPGA is kind of an inbetween of a normal cpu and an ASCI?

[jagged forge]

yeah, that's my understanding

[alpine comet]

yes, that's correct

and not only for data tranmission, for everything actually

because you need to be able to crunch numbers very fast, and there's a lot of them

[alpine comet]

you can even reprogram the gates

so it's not limited to AND, OR, and NOT gates

[jagged forge]

huh

that's a level of optimization i've never thought about

lmao

[alpine comet]

how? well, a gate is just a truth table, and you can configure the truth table of a single gate

just a few bits of info to save

this makes the circuit stupidly fast

[jagged forge]

we have an fpga network card at work that we use to capture data, but i'm like 99% sure we're using like 0.01% of its capability

the only thing we use the fpga part for is to set up a packet filter lmao

[alpine comet]

Now imagine what those wizards in quant firms can do with FPGA

[jagged forge]

indeed

[alpine comet]

remember that for these guys, 20 nanoseconds faster can earn them millions more

[jagged forge]

lol

[jolly junco]

True

[jagged forge]

my company consults with a network engineer who's worked in the finance industry for awhile and he has some crazy stories

i don't remember the details, but he said one time juniper had to design a new switch because all of the traders figured out how to abuse the network switch to place themselves at the top of the routing tree or whatever it was called

idk

[jolly junco]

But doesn't the transmission of data to the building take a lot longer than that?

[alpine comet]

I remember my ex-roommate, who now is working in a quant firm in London, told me that back in the day, one guy was doing field trip to see the signal path. Wires are always faster and more reliable than radio wave

And he found a mountain, around which the cable went. He calculate that if he dug through the mountain, that'd make the signal arrive faster a few nanoseconds

And so he went back to the firm, told the tale, and they agreed. Costed them a few millions to dig through the mountain and reroute the cable, but they earned so much more because of it

[jolly junco]

I'm assuming that all what these nanoseconds are about is the company's stock market shenanigans

[alpine comet]

not only stock market

[jolly junco]

That's a wordy sentence

[alpine comet]

the financial world is much, much bigger than stocks

[jolly junco]

Derivatives and what not?

[alpine comet]

there are all kinds of financial instruments, and they all have their own market

what these guys do is usually market making, i.e. matching supply and demand, and getting the commission fee

[jolly junco]

Ah

[alpine comet]

And for market making, you gotta be fast

[jagged forge]

i wish i could remember the name of it but i think radio is in use today

[alpine comet]

Also they keep their portofolio stable and stuff. So what they do is like, say, try to win 1 cent for every trade

but they do it thousands of time in a second

You are also not supposed to hold a portfolio at the end of the day. When the market closes, your position must be 0

But then again, there are also all kinds of quant firms, and they all slightly differ

[jagged forge]

which makes it a finite time horizon optimization problem

[alpine comet]

So Bellman and his gang comes to rescue, yeah

Although I think I read in Derman's autobiography, at Goldman they had division looking at infnite time problems

I'm not sure, it's been a while

[jagged forge]

yeah i have an optimization book and they touched on both cases

[jolly junco]

The word 'problem' always gets my attention

[dire glen]

hey maybe someone can help me here

[alpine comet]

!help

[quasi jetty]

To ask for mathematics help on this server, please open your own help channel or help thread. See #❓how-to-get-help for instructions.

[alpine comet]

Although, I think we have someone in the server working in quant, no?

@long matrix ?

[jolly junco]

That is not the type of profile I expected

[jagged forge]

oh i didn't realize shuri was a quant, cool

[jagged forge]

listen dude, results are results

[dire glen]

ill try in math discusion

[alpine comet]

and money is money

[long matrix]

who dareth summonth mineself to this lowly dimension

[jagged forge]

megumi and i are rambling about quants for the nth time

[alpine comet]

[long matrix]

cough, i wouldnt really consider myself to be a professional quant or anything really

or like

a

one who deals with stats at least

like a different kind to your usual one

[alpine comet]

Shuri, comfortably typing from Bahamas

[long matrix]

ive had to involve myself with more infra than id like

[alpine comet]

infra?

[long matrix]

infrastructure

[jagged forge]

huh

[long matrix]

coding

you know, like setting up bots and whatever the hell

[jagged forge]

is it like a small company where you wear many hats or smth

[long matrix]

yeah we're small, thats why

so i havent really had a chance to be involved with deep research

[jagged forge]

aw

are you getting equity or smth at least

maybe the small company will become big one day

[long matrix]

if we kick off big

to be seen

still at the startline, about to sprint

[alpine comet]

you guys recruit?

😄

[long matrix]

not now

If I had to say, I'm more interested in the modelling side of things

rather than stats

[alpine comet]

well, I'll graduate in 2 years let me know

[long matrix]

like there are so many nice models/systems that come out very basic math

highschool level kinda math

[alpine comet]

I will certainly get disownned by everyone in my current uni

[long matrix]

those are the things I like looking into

[alpine comet]

but i don't care

[alpine comet]

I heard that in quant one doesn't actually use fancy math

if you know linear regression, you are good to go

[long matrix]

well depends what kinda quant really

[jagged forge]

plz dont tell me u use technical indicators

[long matrix]

but in practice, most math is done for you by a bot or lib or whatever

[long matrix]

you know, this is a very interesting topic for me

that ive thought about for a while

how much of it is sorcery

how much is not

[jagged forge]

i am also told it's not entirely sorcery

[long matrix]

My experience so far - theres a lot of crankery and sorcery here, but at the same time, theres some truth to be had

theres a lot of things.

one of them is game theory aspect

if everyone uses the indicators, they self fulfil

if u get me

[jagged forge]

hmm

[long matrix]

thats one element that makes them more reliable than guessing around

[jolly junco]

Seems pretty logic-heavy compared to what I expected it to be ngl

[long matrix]

so with stuff like options modelling

you usually consider the price to be brownian motion

lognormally distributed

but that goes against the whole idea of technical indicators

its like 2 different worlds

and I think a better model does something in between, so that interests me

[icy locust]

INVERSE indicators

[long matrix]

the price isnt truly random - its skewed in ways, and if you can figure how, you can price your options better

better than just assuming its a stochastic process that doesnt care about what happened before

[jagged forge]

i know there are some volatility models with like, mean reversion

which vaguely sounds like a few technical indicators

[long matrix]

yh but even just mean reversion doesnt capture some of the 'events' that you can see coming

everyone knows its coming up, but dont know the outcome

like FOMC, or some announcement or whatever

elections

[jagged forge]

hmm

[long matrix]

so yh, this kindof stuff interests me

[jagged forge]

i literally have access to market data for free and i still can't be bothered to start studying it

[icy locust]

"Statistics" discord server

hmm

[jagged forge]

maybe it would give me a push if i just like, put a small pile of money in an account and tried to trade lol

[long matrix]

trade it to force yourself (NFA, u didnt see me say anything)

[jagged forge]

[jagged forge]

but u know what they say, gotta have skin in the game

[icy locust]

[jagged forge]

i wish i was into crypto

50% of jobs for the programming languages i use are crypto

[long matrix]

well its not hard to get in

[jagged forge]

true but i dont want to

i both want to and don't want to

[long matrix]

yh nah, perfectly understandable

its not a great place

[icy locust]

can i use my discord account as collateral

[long matrix]

looking for some ponzis? come come

blockchain tech is interesting tho. cryptology behind some ideas

oh no its ryc

[jagged forge]

one time this recruiter called me about this job opportunity at some crypto company making their own cool blockchain

[deep mango]

Time to pay up 🔨

[long matrix]

i pay in hugs

[jagged forge]

we talked for 30 minutes and at the end he's like "oh by the way i'm not affiliated with them, you'll have to send your resume to them yourself"

bro why did u call me then

[icy locust]

too late, all your loans liquidated

[deep mango]

Each hug incurs a processing fee

[long matrix]

ill pay

[deep mango]

[long matrix]

[deep mango]

How about this

You pay me in hugs from someone else

[long matrix]

well actually, i was recently stuck thinking about how a decentralized borrowing/lending system could work, in general

[icy locust]

decentralized CREDIT

[long matrix]

like centralized, the rates are set by banks/gov

[icy locust]

CBDC but it's debt token

[long matrix]

but decentralized, variable rate, no fixed duration loans, was curious. didnt look into it, just a thought experiment

[jagged forge]

surely you can do it with smart contracts

idk how they work tbh

[long matrix]

not about coding it - but how would its market work exactly

is what i mean

[jagged forge]

oh

sorry i have coding brain lmao

[long matrix]

like i couldnt think of way where it 'makes sense'

with proper market competition to control rates

im probably missing something idk

[icy locust]

It's not sufficient that you validate your address payables

[long matrix]

like my thought process was variable rate market can only come from a fixed rate market

you cant have the 1st without the 2nd

[icy locust]

You should actually make an effort so people won't drain all your liquidity or value out of your defi

and somehow make people believe you won't rug

but this is just general defi protocol stuff

[long matrix]

nah i mean more theoretically

fixed rate, you have a bunch of makers (banks irl) who offer loans or want to borrow at certain rates

and thats like an orderbook

[icy locust]

orderbook doesn't work well on most chains i think, frontrunning risks for example

[long matrix]

no no, im not concerned about that yet

lets just say they can work

but the problem is how can you get variable rate loans

on an orderbook

i wanted to figure this

[long matrix]

lets say our book is of 1-week loans.
Then I can have a bid of 1% (im paying 1% to borrow), and an ask of 2% (im being paid 2% to lend)

i just dont see how you can have a similar 'book' with variable rate

variable rate seem to be a bit like perpetuals that would track the fixed rate book

[icy locust]

surely it's not variable rate as in some fixed function of time and principal price

wel

[long matrix]

if you just have a variable rate book on its own. Say everyone's open loans are charged at the rate of the midprice on the book

theres nothing to stop price manipulation happening and liquidate all loans

[long matrix]

the price on the book doesnt mean anything in a sense with such a design

stepping aside, unlimited term loans are desirable over fixed term, but to enable unlimited term, you need variable rates. is why i was considering this problem

(and I dont think ive seen any solutions that use an orderbook, so maybe theres none)

[icy locust]

https://consensys.io/blog/serum-a-decentralized-on-chain-central-limit-order-book what was consensys cookin

embed fail

[long matrix]

meh most protocols are copycats of another

with a few improvements(?)

there arent that many novel ideas in the space, really

[icy locust]

so if one gets rekt due to a bug, all of them get rekt as well

[long matrix]

well, they're not necessarily forked

often they're reimplementations

"we'll do it our way, its a new product", but just copy a lot of ideas

[icy locust]

so you invent a novel market design and fail to notice a flaw and you get rekt

[long matrix]

well all of the widespread ones will have gone through audits, but yeah, plenty of exploits have and will happen

[icy locust]

so anyway idk if consensys actually has a working orderbook model

[long matrix]

a lot of them occur cus of flash loans existing

there are plenty of DEX's running an orderbook model yeah

some are completely decentralized, so stop losses, liquidation prices are visible for all to see

and get hunted

I think protocols are looking towards zero knowledge proofs to solve this problem

[icy locust]

and get...regulated?

oof

yh idk there's got to be a way

im just a bit of pessimist

[tulip viper]

ok my gf is a higher achiever and she tries her best but she has period cramps and during those times I try to comfort her by buying her some food and massaging her but this prevents her from being her best for an example 2 days ago she got it and she had an exam the next day but she couldn’t study for it because she was in pain - does anyone know any medication i can buy for her that’s safe

[small dust]

advil

[urban nexus]

Probably best if she talks to her doctor about it, the doctor will know her situation best, giving advice on medicine without her medical history could be unsafe

[tulip viper]

thank you I will try talking to her parents

[ocean harbor]

it is only one day that gives you a pain

if she gets pain more than one day then definitely go with advil

[tulip viper]

what should she do on that day

[tulip viper]

I think it’s better to get a doctor first

I don’t want to make her more sick

[small dust]

advil is like no risk for most people

[ocean harbor]

how old she is? if it is not for the first time then she will be fine

you need just to get used it

[tulip viper]

She is 16

hmm if she has a lot pain then ya definitely see a doctor

[tulip viper]

Yea I try to support her but even one time I came back from the store and I saw her crying

Hello discussion 2 aka cold side of pillow

[neat lintel]

😂

[neat lintel]

What is the differenece between Differentiation and Integrate?

[ocean harbor]

differentiation is like find the derivative

and integrate is integration of something

[vivid halo]

They are inverse to each other. If you take the indefinite integral of a function and then take the derivative of that answer, you get back your original function

Definite integrals are related to the areas under a graph between some endpoints, indefinite integrals are running the process of taking derivatives in reverse, the two are related by the fundamental theorem of calculus

[mint patio]

Aren't there some conditions to this

I feel like I've heard of pathologies with like antidifferentiable functions whose derivative doesn't exist or isn't equal to the function you initially antidifferentiated

[alpine kindle]

stomke's theerom

[mint patio]

I almost thought you meant Stokes' for a second and was like what

Let me look at that 🤔

uh

I cannot find any Stomke's theorem on Google

LOL

[alpine kindle]

remove the m

[mint patio]

LOL

Wait what that gives the conditions for d/dx int = f(x)?

[glass peak]

I mean the fundamental theorem of calculus does and stokes theorem is a generalisation of that

In some sense anyway, it feels weird to say that, but the FTC is a special case of generalised stokes

[surreal bison]

the same way any language since the start of programming languages does

similarly to orbits in a non coulumbic/hookean central force, or a geodesic on the torus, it's closed iff some parameter is rational

[vernal token]

Does topology have any other pre-requisites than some analysis?

[latent edge]

just go with it

[vernal token]

Are you saying real analysis is enough as a pre-req or can you even go at it without that?

[latent edge]

No I mean just study topology and don't worry about the prereqs

[vernal token]

Ah, so refer back when there is something you need

Alright, thanks

[rocky shuttle]

point-set

[glass peak]

Even analysis isn’t strictly required

I would recommend it, but it is possible without it

[river moon]

what's up with people that went through a topology class saying every class or every topic they give a talk about doesn't have much prereqs

and when you listen to it it's like nearly graduate class

[glass peak]

I mean topology is a final year course at my uni, it does take some comfortability with maths, but it doesn’t directly require you know to know analysis really

Like if you know set theory you can get pretty far with topology

But I agree it’s going to be rough if all you’ve done is like calc, it’s just low in formal prereqs, higher in maturity

[neat lintel]

guys, I hope nobody takes it the wrong way, but why do people straight up post pictures of all their homework problems directly into the help forum?

[latent edge]

mfw walking into a rep theory seminar having no idea what's going on and when someone asks me what I understand I just talk about langlands

[neat lintel]

you're right, but it does seem like sometimes people just screenshot/take a picture of their entire PSET and just wait for someone else to do it and thne write it down

[ocean harbor]

just do !nosols

and they will understand

i get sometimes ppl giving them free answers

[viral patrol]

Just wanted to let you know that I've started working on something new. It's in the early stages

My blog

[ocean harbor]

nice

[surreal bison]

better than giving ~0 information and expecting help

[neat lintel]

wait did I do that? if did I'm sorry lol.

[surreal bison]

no

i just meant that many do that

[neat lintel]

gotcha. I assumed I did it because I actually posted a question, someone answered it adequately and then I closed it. My title was need help with " X ".

[neat lintel]

a question .
Because there are authors who define an Orbifold space as an idea of understanding in a product of symmetry. For example, if a curve C has an orbifold it is C-> Sym^d, this is because every curve C has a corresponding product-symmetry. The question is what connection does the orbifolds have for a given product-symmetry?

[minor current]

how many daily

or is it according to mental exhaustion

[tulip viper]

hello 👋

[neat lintel]

I average 3 a day

[neat lintel]

and yes

[glass peak]

I go on many a wander through the day

Usually when I feel myself getting distracted or stuck on a problem, I’ll just take a little walk and it usually helps

[patent stump]

Should I take a harder sciency math class (Fourier analysis) or an easier engineer review math class covering Lin alg, ODE and complex variable?

I’ve never taken a Lin alg or complex variable focused class, but my Fourier skills are weak and a lot of the topics interest me.

[glass peak]

Is it Fourier analysis for mathematicians or Fourier analsysis for engineers?

These are wildly different courses and you will have no chance in maths Fourier analysis if you aren’t already quite comfortable with analysis and pure maths (it also won’t be all that helpful to you)

Like if you just need to know how to use Fourier methods to solve DEs and stuff definitely go for the engineering class, you don’t need to know about Schwartz spaces or any sort of harmonic analysis if you’re more on an engineering path

[patent stump]

The Fourier analysis is taught by the ECE and its applied to signal analysis. The math course is taught by the math dept but targeted toward engineers

[glass peak]

If it’s targeted towards engineers it could be good, I assumed it would’ve been more harmonic analysis if it’s a school of maths course

[patent stump]

I would just pick Fourier but I’ve never had more than a lecture or two on linear algebra and just kinda guessing along the way to get through courses that require it

Fair I should have made that distinction

[neat lintel]

I think i have one of the best teachers for people who dont like doing a lot of work

4 homework assignments and only two tests, final is optional

Unfortunately, we barely learnt anything

[river moon]

that's what you get for not doing a lot of work

[latent edge]

I swear I learned more math in my self study shenanigans than I did in school/university

[sleek pagoda]

it's not just that, even if I learn something at school, it seems useless and not really "natural" where as if I learn something at home I feel like I get a better understanding

Hello

[deep mango]

Im here

[arctic grove]

i am also barging in here

[deep mango]

Ok

Anyway

Shyshu did you know about my date

Idk if you want to hear about that

I dont remember

[arctic grove]

i dont know anything about your date

i just know that you went on one

[arctic grove]

i do wanna hear!

[deep mango]

Ok well, it was great and he was perfect and my suspicions that he was a serial killer were unfounded

[arctic grove]

im sorry what

[deep mango]

Uhh

[arctic grove]

why did you suspect that 😭

[deep mango]

He wanted our first date to be at six flags, which i thought was cute but then my dad was like "how do you know hes going to drive you to six flags"

Which is a valid point

So i said maybe on a second date, and then on the day of our original date he "lost his phone in a sewer grate" and couldnt contact me and missed it

[old oak]

Sounds promising so far

[deep mango]

Which i was mad about, but then we just scheduled it for the next day and it was like

Surprisingly normal

[arctic grove]

[deep mango]

And also amazing

[arctic grove]

thats really nice to hear

[deep mango]

Yeah it was so funny

[old oak]

Definitely not a turn of events I was expecting

[deep mango]

Right??? I think hes just kind of scatterbrained

[arctic grove]

very well suited for you then

[deep mango]

No!

[arctic grove]

yes!

[deep mango]

I mean yes

Like

[arctic grove]

why do you have to disagree just to agree at the end smh smh

[deep mango]

But its not a good match because im scatterbrained

[arctic grove]

but also sometimes you are not

so its like, fine

[deep mango]

Its a good match because I need to be made to go with the flow a little more

[deep mango]

Im not scatterbrained!

Thats what im saying

[arctic grove]

huh, thats interesting

[arctic grove]

lol

[deep mango]

Idk, most people I feel like i need to control the narrative and conversation around and stuff

But i just felt normal and non performative talking

So that was nice

[arctic grove]

thats so cute aww

[deep mango]

Honestly it wasnt an instant click or anything and when I say hes perfect I just mean hes really hot. But I am pretty certain wed make good friends

[arctic grove]

its a win win regardless

[alpine kindle]

hi hi hi

[deep mango]

Yes i agree

[arctic grove]

hallo

[deep mango]

Hello ally

[alpine kindle]

hehehehehello

[arctic grove]

i need to go out with someone i will lose it otherwise

[deep mango]

Finally this awful lecture is almost over

[alpine kindle]

lose what

[arctic grove]

lose my mind

[deep mango]

I havent paid any attention

[deep mango]

Soon!!!

[alpine kindle]

What's the lecchair on

[arctic grove]

you are using your phone in the middle of class? how awful of you ryc!

[arctic grove]

what

[deep mango]

Wavelets and holder continuity

[deep mango]

Yes

[alpine kindle]

aren't you a phd student why do you have mandatory lectures

[deep mango]

Its not mandatory. I didnt know it would be so boring

[alpine kindle]

oh

fair

[deep mango]

I mean im enrolled in the class

But theres no work or attendance or anything

[arctic grove]

holder continuity? like the uniform continitity alpha>0 type?

[arctic grove]

what do you mean ryc tell me!!

[deep mango]

You will find a date soon

[deep mango]

Yes

[arctic grove]

how do you know, please tell me

[arctic grove]

interesting

i once went through my dads book on wavelets, and it was pretty cool

[deep mango]

Youre less and less active online, which means youre finding more and more friends in person!

[arctic grove]

i mean i guess

im in a weird situation atm, where i ended up catching feelings for someone who i should not have caught for

and now i am writhing in pain

😭

[keen lake]

Discussion 1 is going crazy

[old oak]

Isn't it always? That's why I'm hanging out in here

[keen lake]

Hmm

Do you know calculus?

[old oak]

I've heard of it, why?

[keen lake]

please tell me should I learn Trigonometric rations for it ?

[old oak]

I don't know what trigonometric rations are, but generally having some familiarity with trigonometric functions and various identities is helpful.

[keen lake]

Ohh , btw do you think learning things is good instead of just understanding them ?

Because we learn them automatically if we keep doing and doing

[old oak]

Understanding how things work and being able to do them routinely without much thinking are both useful (to various extent in various contexts). I understand quadratic functions and I could derive the solutions to 5x^2-13x+2 = 0 from first principles, but I've also had some practice with quadratic equations so I can write out the formulas and the solutions without much mental effort.

[keen lake]

Hmm

Btw i also know quadratic polynomial and equations

But i don't Know what are functions

[vernal token]

Btw Outsider, would you consider it "informal" to write $\lim_{x \to 0^+} \frac 1 x = \infty$? I'm asking about the $= \infty$ notation.

[old oak]

You can define the statement $\lim_{x\to a} f(x) =\infty$ formally.

[fathom swallow]

Outsider

[old oak]

And in fact you should if you're doing proper analysis.

And then you can use that statement without worrying that you might be informal

[vernal token]

Ah, makes sense, thanks

[deep mango]

Uh oh

I understand

I do that a lot

[vast surge]

What this sentence means is "as x gets closer to 0 from the right, 1/x becomes a very big number".

[old oak]

Which is also not formal, but gives an insight into how to formalize it

[vast surge]

Sure.

It's not technically formal, but it's what I remember and then I reinvent the formal definition each time I need it

[arctic grove]

yeah, the girl i ended up liking is a good friend who is also not into men and kinda aroace

😭

kms

[deep mango]

Aww :(

[vernal token]

I know, I was really more asking if you'd be allowed to write this if you wanted to be very formal

[vast surge]

Yeah

If you know the formal definition

[arctic grove]

yeah, this makes the guilt i have about liking her worse

im just hoping these feelings go away

[deep mango]

Its just like what I do with straight guys! It sucks but you also get to like them without worrying about ever having to act on it

[arctic grove]

not acting on it is making me go insane

[old oak]

If you wanted to be very formal you'd have defined the meaning of this beforehand, but also the formal definition is very standard and often included in textbooks/courses.

[vernal token]

I guess a slightly modified epsilon-delta definition

[old oak]

For example see Abbott here:

[vernal token]

Seems like that's exactly it

[old oak]

Rudin as usual does it in a less clear way:

[fallow iris]

If a, b, and c are not equal to zero, what is the difference between the maximum and minimum value of S?
S=1+|a|a+2|b|b+3|ab|ab−4|c|c

anybody know anything about coq?

[alpine comet]

Avoid it at all cost

[left haven]

i really wish i could but i cant

for some reason its what we use at my uni for algo and data structures

this will probably be the reason i drop out of cs

[left haven]

idk anymore man

i cant find anything online

its so frustrating

[alpine comet]

Yeah, that's the thing about Coq

You kinda have to find your own way

One crucial tip I can give

Is that you have to make the lemmata stupidly simple

Then combine a lot of them together

Big proofs don't work well with Coq

[left haven]

ik i am cooked when i dont even know what lemmata is

[alpine comet]

Plural of lemma

😄

[left haven]

i am cooked

[alpine comet]

You can make it

[left haven]

i hope so

i genuinely hope so

[cinder zephyr]

why would a data structures and algos class use Coq???

huh?

what why?

I see 0 connection

After my recent hospitalization, I decided to try to take a break from doing math until the end of May. I'm three days out. I have an overwhelming urge to do math - not even the math for my courses that I'm taking incompletes in, but just math that I want to study for fun.

do math that is fun! it doesn't have to be work

I personally have to take lots of "breaks" by doing math I find fun instead of doing math that feels like actual work
