like 98+% of it is literally word for word 
the average freshman is better than this
wdym it's not word for word
it basically is
every thing thats written aside from code gets repeated word for word
depends on where you look
at times it could be that half of what he says isn't on the slide
you're overestimating what average freshman presentation looks like
Great video
any presentation that uses slides is probably shit, and 100% certainly shit it it lasts more than 20 minutes
that's a very extreme take
Also just an objectively bad take
bad take, but also most slide talks are kinda bad
chalk talks are almost always better than slide talks
although I've seen some really good slide talks that would be kind of disasters if they were chalk talks
also most slide talks are only bad because most talks in general are kinda bad tbh
most people just do not give good talks
Chalk Talks are better than slide talks IMO because of a few factors
- Most slide talks don't actually need the slides to present material that would be hard to write / draw
- Chalk Talks have natural pauses and such due to having to actually write
- Multiple boards visible at once makes the talk seem more seamless
really the important part is the first one
yeah definitely
if you're presenting material that needs precise diagrams (think combo usually)
then use slides
the main cases I'm thinking of are talks where there are diagrams that would be absolutely horrible to draw on the board but are like, the main point of the talk
even in those cases it's sometimes better to like, do a hybrid between chalk and slides if the room allows for it
because I think giving an ok slide talk is easier than an ok board talk
some rooms are large enough where you can project slides above the board and then yeah that's great
if the screen blocks the board then yeah that's hard to do
like I'm not writing that out by hand
I've seen some knot theory talks where it would be absolutely awful to try to draw all the diagrams on the board
I will say the biggest issue with slide talks is that its easy to write too much
and so you end up with people reading off the slides
where for board talks people realize you can't write that much
slides can definitely be done well if you are aware of these issues
the other thing I've seen done really well is like "slides" where you leave a bunch of empty space and then actually write stuff on them with a tablet or whatever
but then have certain equations already there that would be too annoying to write out by hand
yea I've seen this done alot
that's an underrated option
my algos prof did that, it was great
yeah I really like this option
https://www.ams.org/profession/leaders/workshops/gcoll.pdf
Most colloquia are bad. They are too technical, and aimed at too specialized an audience.
first line
I also saw a great piece of advice which works well for more complicated stuff
where you just lie
in that say a proof is very complicated
but that complicated part is for like 10% of cases that you'd only come up with when doing the proof
just present the simple proof of the 90%
best talk I've ever given I ended it early and then it had 40 minutes of discussion at the end with profs in the audience
chances are few if any will notice
and if anyone does notice you can mention that lie verbally
but it ends up being a smoother talk
Hm I'm trying to think what the best talk I gave was
might be the one with these slides lol
from last spring
in my first talk I was asked why something was true, but I gave a very bs response (answer was really simple but I forgot) and the prof just nodded his head
Well there is a difference between bad talk and not knowing stuff
very similar to the idea of a good-researcher-but-bad-prof
Okay for a second this sounded like you ended it 40 minutes early...
Like oh hour long talk? More like 20 minute talk
Which would be wild
probably didnt want to seem dumb
same lol
I feel like I gave a good ten-minute talk recently; I stayed pretty surface-level, but it had good flow, motivation, and energy
The audience seemed to like it at least
I want to put together a 10-15 minute talk
for a small seminar at my school
gotta think of a topic (should be computational in nature)
most likely, or didnt want to embarrass me
How does one comprehend this?
by reading the whole context of the prior slides to that one + hearing the associated words I was saying while giving that presentation
I mean like I can't give the whole presentation here lol
Yeah
I replied "We don't have those LMAO" to a question about my assigned academic advisor.
Does anyone in undergrad actually have those?
I asked the people at my college and they all said no
do you not sit down/discuss your coursework plans with anyone?
no
google "[your college] undergraduate academic advising" and see what comes up
Who here has learnt number theory?
How many times in a day do you use what you learnt from it?
I started learning it for competitive programming. I have to say I've used it about zero times
I will put together a 10 hour talk on GA
I actually have one question I want answered that I have yet to find an answer to with my limited looking
I wanna know where the octonion GA is hiding
Of course the octonions themselves can't be in a GA, because they're nonassociative
But if I'm not mistaken their automorphism group is a lie group
Which makes it isomorphic to a subgroup of the spin group of some family of GAs
Particularly, there's some smallest GA with G2 in/as its spin group
I want to know what it is
@zealous garden wow very surprising. glad to meet you.
Very honest of you, nice to meet you
thanks
probably you are very fond of maths, u live in Japan?
what do u mean?
Does yakuza live in you
lmfao
I am really starting to think that GA is a cult
i have some doubts about GA totally encompassing exterior calculus
What is there to doubt
Just look at the respective tensor algebra constructions
T(v)/<v^2> is clearly a special case of T(v)/<v^2-B(v,v)>
the existence of a clifford bundle on any smooth manifold which requires some representation of the spin group which requires spin structure. While exterior calculus is generated by exterior powers of the cotangent bundle which is always possible
I believe they're also naturally isomorphic if you do it right (symmetric bilinear forms instead of quadratic forms)
spin structure
I don't know that word, you just need a metric to have a tangent algebra at each point.
And the zero metric works
I can also use a vectorspace and it's dual space to make the mother algebra
well Im referring to how GA works on manifolds
So the tangent and cotangent bundle combine to give me access to all possible GAs at every point
What is the obstacle, what is restrictive about spin structure
it obstructs a consistent choice of spin group representative at every point that passes down to the special orthogonal group (which is determined by your metric)
and iirc, GA algebra always admits a faithful rep of the spin group
I don't know what faithful rep of the spin group means
Just faithful representation of spin group?
If you mean the ability to exponentiate bivectors to get automorphisms that are continuously connected to 1, yes
let me look into this
yes
No, I'm a cult
Do not be confused

literally every day
bro @dusk talon what did u send in here bryh 😭 u cant just drop that word and delete
What would be the correct way to study group theory?
What does that even mean
There are standard ways. I don't know if there's a "correct way".
group therapy
Fraleigh -> Rotman + Borcherds YouTube lectures
solving all problems from D&F till you experience hairloss
Thats one way, and I wouldn't say its "correct". Its not what I did
You did it wrong
Okay ryc
Group theory is overrated
But I used Dan Saracino's textbook for a first course in group theory
And then later read D&F

🤢
Group theory kinda mid after a point
Yet he thinks he learned it correctly...
No such thing
Only incorrect ways?
There are ways that work for each individual person 
Fuck you
How the fuck you put Galois theory in the valley
Galois theory >>>>>>>>>>>>>>>>>>>>>>>>>>>>
^ gives a fuck about prime powers
Ur just unenlightened
Enjoy
In my experience, Galois theory took 2 passes to fully appreciate. First you learn I learned it abstractly for fields (Dummit and Foote). Then i put it in context with number fields (Marcus). I actually only 'got' Galois theory once I saw it being used in the study of number fields in algebraic number theory
I thought to follow David Cox (saw it today in #book-recommendations)
Well I still got a month, I should review some rings and fields in that time.
I too only looked at the index, it got some historic notes in every chapter, so I thought that would keep things more gentle and interesting.
Thats cool
Oh no, why?
I guess I likely did not understand it, because in my eye it was entirely permutation of roots/extending generators
Students didn't know ring theory
oh
How are they expected to do Galois theory if ring theory isn't a prereq?
@bronze pelican
Are you expected to give a crash course in it?
I just skipped all the parts that had to do with ring theory
I'm using Jacobson rn (im at chapter 1: section 1.5), its been great so far. See sloth's intro alg reviews in #book-recommendations
but yeah there's no definitive way
I am interested in Galois theory because I want to figure out what about finitivity forces F^Stab(K) = K to hold for intermediate fields
I think it’s due to Artin’s Lemma. But a lot of it uses vector space magic
the vacuous Galois theory
"wdym this element has no multiplicative inverse"
It maps a function f to its value at x
I think x would start with 100mg
63565984e
the letter after w
my experience with my first group theory class was mostly good...
but fuck group actions, I hated proving stuff with those, it all feels like pulling a rabbit out of a hat by doing some weird obscure action
group actions are group theory
Pulling a rabbit out of a hat, that seems to describe entirety of math for me
Rabbit out of a hat
yeah they're important
but it's annoying when you need to use them
a lot of that stuff was still cool though
I see what Namington is saying though, group theory is mostly just cleverly applied group actions
Like you get a lot of it that way
you do, and I don't like it
because the proofs are hard to see the motivation behind
Fair! Makes sense actually
I have to assume they just tried a lot of actions to see what they could get
Yeah, probably.
nah I'm actually hitting group theory rn
Hold shame
Is there anyway i can learn math without a pen and paper
A tablet can completely replace pen and paper.
true, but a tablet cant do caligraphy
i dont completely believe digital art is the "future" of art
then it is exceptional case
yes
i don't even know
No its the present
talking about the future not the present day
just think about it like a subgenre
it is just objectively another medium for art
dont got a tablet just a laptop
Why without pen and paper?
You can probably get some drawing pad that you can connect to it so whatever you draw there appears on your screen
Just saw Cauchy's condensation test and just wondering... can't you also do that for $k^nb_{k^n}$?
bluepianist
like what works for $\sum^\infty_{n=1}2^nb_{2^n}$ can't it also work with $\sum^\infty_{n=1}3^nb_{3^n}$ for example? Haven't really worked this out with pen and pencil yet, but it seems reasonable?
bluepianist
yo what are some good books to learn probability and statistics?
I liked Ross's A First Course in Probability
well written, good examples and problems
@crude trellis
$b_1 + (b_2 + b_3) + (b_4 + \dots + b_9) + \dots \geq b_1 + 2 b_3 + 6 b_9 + \dots = (b_1 + 2 \sum_{i = 0}^{\infty} 3^i b_{3^i})/3$ and $(b_1 + b_2) + (b_3 + \dots + b_8) + \dots \leq 2 b_1 + 6 b_3 + \dots = 2 \sum_{i = 0}^{\infty} 3^i b_{3^i}$.
Raghuram
So the convergence is equivalent; if you're looking at the explicit bounds relating the values of the sums, that might be a bit more complicated.
Assuming the terms of the series satisfy $b_1 \geq b_2 \geq b_3 \geq \dots \geq 0$.
Raghuram
dose anyone know a graphing website which will let me plot something like this ((π)/(2))≤arg(z-1)≤((3 π)/(4))
Wolframalpha should
Seems to not be the case
,w plot pi/2 <= arg(z - 1) <= 3pi/4
,w pi/2 <= arg(z - 1) <= 3pi/4
Works fine though, just not plotting it

Thanks a lot man , will look into it 🙂
does anyone know polynomials
Whats the question friend?
i just have a test today and im confused on some things still
have you not studied anything for it
I had a really weird dream two days ago
I dreamt of having a CAS that was better than WolframAlpha
It had a rather bad interface, it looked like Maxima
yuh
polynomials such a W bro, as well as geometry
easy topics but my classmates struggle with em so i feel a sense of superiority every time
Yeah?
I would-be glad to help but timelines seem strict
I TOOK THE TEST(hiding my phone under desk) AND I DID GOOD I GOT 100%
Academic dishonesty is frowned upon in here.
why do middle schoolers always take in this weird voice like they're always afraid
maybe it's just here and it's an accent that goes away idk
what i notice is they pronounce a lot of vowels weirdly and also lengthen some vowels out for some reason
not like anyone tests you anyway
what
you'd be surprised 
i mean good for you
but dont do this for g+ lol
find better (intrinsic) motivation
i mean building motivation is hard
but maybe you should work on that first
getting good at mathematics (assuming this is your goal) takes an extremely long time
i dont think getting good is the only thing that should be on your radar
for math
live a little
huh is there a test for g+ lol
Theres no “test” you just explain your education and name drop a few papers or textbooks you read recently
its no more than 100 words
damn dont make grad+ ur motivation
what happens after u get grad+
this kind of motivation isnt sustainable
You attain discord validation
yes but then what, what will make you want to continue math after that?
The highest form of meaning
why would you have to stop
hobbies exist
even if you spend the next 5 (or 10) years doing math full time, it is very unlikely that you will get a long-term job doing mathematics
try to not set yourself up for failure
my suggestion is be open minded and find intrinsic motivation in the things you do
again, the odds are only against you to do research math full time, not just to "continue doing math"
grinding for a discord role isn't gonna sound good no matter how you phrase it
see you on day 900
i mean g+ sounds like a lot of grind in math
if u value grind in math possitively
then its a good thing?
i guess
Does Algebra Contain most needed for Linear Algebra?
What comes after High School algebra?
tbh I want to form a learning plan so I dont know
Im trying to figure out a plan
Usually people learn geometry, trigonometry, and then calculus after that
Alright, thank you
Does this sound good?
Algebra > Geometry > Trigonometry > Calculus ?
Sure
oh and do those things include statistics or is that seperate
Does anyone have good sources to learn math online?
Khan academy
I really like video games and should I made a games(simulation) to simulate launch it could be on pc and vr and does this type of person that does that could be a ceo of a company like spacex?(This is an very important question for me and the answer could decide my future so be honest with me 🙂 )
perchance
Video game development is generally a pretty bad career path
this really has nothing to do with being the ceo of a company
good thing they already left
I agree
Ceos steal, Engineers build
LOL
Yes you right, I might have said it wrong but I meant: does the ability to make this mean that you have the knowledge to possess and be a leader of a company like spacex.
@solid snow
again, the two are unrelated
You think elon musk has the knowledge to be a leader of a company like spacex?
Yes
Why mathematics won’t be required to prossess and be a leader of a company like spacex?
Yes I mean people that make like spacex, Facebook etc… we’re good engineers
And good at math
Elon musk was not a “good engineer”
Engineers aren't CEOs
Fr?
And what you listed are exceptions not the rule lol
He did a degree in physics and learned concept abt rocket science tought books by himself
Name one thing he’s engineered
any mathmaticains in the chat?
People that do math are mathematicians so if u di math then u are(I believe lol)
Ans yet uses none of that to do anything at spacex
Why it unrelated to spacex? And spacecraft i mean it physics
door handle
The role of a CEO isn’t really anything to do with what you’re saying
It’s about managing people, setting policies, etc
They aren’t the ones building or designing the product for the most part
Then how they come opus witht he concepts
The*
And how they get the ideas and the right ones
okay okay if anyone wanna awnser let me know so you know how you can do 9.999...
would it be improper to do 0.000...1 to represnet infinsmal small value
You’re assuming every ceo is the inventor of what their company does
Which is by and large not true
Lots of them are just dudes in suits with business degrees and good connections
By “CEO” i meant people that made the company form zero and if it is what you meant, then yes.
Thats not what CEO means though
Oh
So youll have to forgive me for not reading your mind
Then what it is called
It doesn’t really have a name as founding a business and inventing something need not be related
A founder
So to be a founder of a company like spacex do I need to have mathematics knowledge
What do you mean by “mathematics knowledge”
No, just $120 to register you bussiness
Then how would you know that your ideas are right then?
they don't blow up
Like physics, calculus, rocket science
No before you do your business, you gonna need a idea
they don't blow up
You have an idea. You do it. It fails or it doesn't
Ok, uhmm I don’t think this is the answer I was looking for.
it be like that
Doesn’t make sense
45% of bussinesses fail in the first five years. If there was just a way to know if your idea is right or not then no one would fail
No not really i dont get why you keep asking. If you want to invent something and sell it, then probably
, any business man even if they don’t know physics will know that starting an company that is not even a 40% chance to work, they gonna look for expert or get the knowledge needed and the “expert” won’t always have the right answer and if they say it won’t work you pay them for nothing.
I want to found a company like spacex(ik it ambitious) but I’m not sure if I need to know mathematics concept like rocket science, physics to start the business from zero as a startup
Business man knows that 1% chance is good enough
can fail 99 times but only need the one to work 
Ok, you right
But does it always better to have the knowledge?
Maybe do some light reading
Does pre university in this server is for 13 or it undergrad?
Cuz I’m 13
?
Yes
Does pre university what
Pre university is if your math level is that of before university
But in this video Elon musk seems to know what he talked abt right: https://youtube.com/shorts/WY73exaVpyw?si=7eGxzQpcQB7OqFCX
If I know algebra only
Like algebra 1 and I’m going algebra 2
That why I’m here
"seems"
Yes
He only seems to know what he is talking about because you don't know
Then tell me
Does he knows?
He has a group of scientists he can pay to tell him to say the right stuff
Did you read the wiki that josemon sent?
When does it say elon did anything besides pay for things or hire people to do things for him?
Theres no doubt that he has an interest in what hes doing and cares about it, but thats a world away from the actual engineering of the rocket
Yes a bit but not all, I learned that he had a contact of a scientist and made a group of for him
Elon Musk seems to be not especially intelligent in his own right
Go further please. I don’t undestand what you meant by his own right
By himself
He’s good at making money which I respect
Are you sure about that?
Bro
He's a billionaire with a large PR team and a lot of weight behind him but things like the hyperloop pods are just worse versions of existing ideas
You can hold more people and have less friction with a train
Yeah hes going to go out completely clueless about his projects. Totally not a PR nightmare
So his group of scientists told him what to say, even if he never knew the exact question this YouTuber was gonna ask?
No im reading what you said and what I undestood based of the video
My knowledge about his study is limited to his university, degree and companies
Yes i had, why?
Then you would understand what having a general overview od something means
Woah that's beyond stupid
Just having 'advisor' yes men for his own ego
Not really
They dint work for free and he wants to know what theyre working on
That’s what I mean by that
Yes, but it just the fact that he has this exact ideas to change the things and his mind, someone with a resume wouldn’t be able to solve a problem or even think about a problem solving situation without a answer of someoen asking the question
Sorry
Oh
Ah sorry
I’m also french so
Do you learn by watching video
What problem dis he solve exactly
Guess I am old
Never form shorts
Well, that's "potato, tomato" to me
You're falling for the propaganda
Ok and why and how I could prevent from falling for the propaganda
What you meant by that?
Realize that the people actually making the changes are the engineers who are building the rocket
Short form video is not that different from lengthy videos
In terms of learning yes
People cannot explain better in a short more than a 10+ minutes video
..no, one can be informative as much in both form
Just because it "seems" elon got an idea from a random youtuber and made a change does not mean it is so. Elon is not the one designing anything
Oh bruh
Elon's name is only on one patent
and the patent is for a door handle
Then I a new thing I just learned here
What
I mean like mathematics, concepts etc…
Yes
Breh
Both are in visual form, so usually you can explain in both if you try
“If you try”
That is, if you are ever going to deliver credible information
Then you should be able to do this
Tho ofc majority of youtube is just, lol. They are not reliable in any sense.

Noooooo muhammad 
Don't they do this a lot?

<@&268886789983436800> spam, also in other channels
kindly cease
that took a while 
don't really find the ability to bullshit a lot of people something to respect
and without rich parents he would have never made money
its a skill
everything is built on bullshit
no?
see you are even questioning it
more like questioning you
how can can come up with that
you think the device you are using is bullshit?
everyone is bullshitting us
perhaps
not perhaps
plus some bullshit on the side
can you say something concrete?
are you saying im speaking bullshit
you do realize that you, an individual, speaking bullshit, doesn't translate to everyone?
of course
thatd be bullshit
@plain owl wouldnt you say a lot of the world is built on capitalism
that is a categorical error
its the reason we get innovation
What did I walk into
wouldnt you say that governments and corporations love to bullshit us though
you're changing the goalposts
i mean everyone knows the news is filled with bias reporting
you said that it's a respectable skill
its bullshit
Ill touch on this in 5 min
i never said the word respectable
i said its a skill
and it is
Give me a sec
people get paid to be professional bullshitters
here
you replied to "to respect"
if you didn't think it was something to respect
why reply at all
i was giving my input on bullshit
besides
bullshitting is human nature
maybe im just being a human
no it's not
not like that
most people find it rather immoral
and plenty of the time it counts as fraud as well
everyone bullshits
what kind of lame attempt at a moral highground is that
theres just different degrees to it
i have no moral highground
you are the one claiming it
you bringing up morality and fraud
yeah, turns out that lying to people is considered immoral in virtually all circumstances
nope
fraud is a crime
well, I'm happy to not be you
there are also stark differences between objective and subjective statements
that's also not how mature people communicate
YOU are bullshitting
it comes in all forms
I'm not
im not saying you
tell that to the people that went to prison
over fraud
of course it matters
in the context of what is bullshitting
im not saying generally
anyway, this is a supremely stupid discussion
its common in business as well
yet you choose to participate
social "niceities"
bullshit
you know a study found that bullshitting is a sign of intelligence
i dont understand why are you so against it
its a foundation of our society
I don’t disagree with this, it’s just that making a lot of money is a win condition for the current system we live in
having rich parents is a win condition
Indeed
Sadly I don't think it has been much different in other eras as well
I'll say tho that a self-described self-taught prodigy is fanboying for Elon is quite funny
yes, but it seems to be getting worse
wealth is concentrated further and further
Yeah it is worse than e.g. a few decades ago
Tho I don't even know what the solution would be
Nothing I can come up with is realistic
because rich people are in power
and globalization has destroyed the ability of nations to deal with them
Yeah, I am in fear of what could happen
Sup
global inequality has gone down (significantly) over the last 30 years
I'm talking about ultra-rich individuals being able to threaten countries with not paying taxes there
the ultra-rich have gotten a higher percentage of wealth by far
what you're talking about is more of a consequence of the industrialization of very poor nations
globalization, because industrialization is different from being able to sell your goods on the global market
its almost down to the levels of the year 1900, which we all know was a time where everyone was equal 
mophra how advanced are you, you seem very knowledge
why are you asking that here 😄
but you're talking about global inequality, globalisation does nothing for you if you have no products to sell to begin with
this is a weird response - your response to "hundreds of millions of people have been lifted out of poverty" (like in China) is "actually, they don't have anything to sell in the first place". Look at literally anything you buy - there is an extremely high likelihood it manufactured in ex China/Bangladesh/etc
and that is called industrialization
and again, your response has nothing to do with my initial claim
,w x=ye^e^y find the fifth implicit derivative with respect to x at x=0
how do i get wolfram alpha to evaluate it?
its just finds the derivative but doesnt evaluate it
,w x=ye^e^y fifth implicit derivative at x = 0
i dont mean a partial derivative, I just want $y^{(5)}(0)$
The Great D
the value of it
How did you write that
wdym?
aside from x, you also need to provide values of y(0), y'(0), y''(0), y'''(0) and y''''(0)
which I doubt wolfram alpha can do on it's own
well if it can come at y'''''(x), why wouldnt it be able to find the loewr derivatives?
because it's not an all powerful tool
There's probably some way you can do it
math has gone too far
Yea fr
Its a combination but mostly globalization
You could argue that existence of a global market would increase demand to drastic levels in a capitalistic society
Think about if you are a company and you have a demographic of 100 people to sell to and manage their needs
Because of this you hire 10 employees
well the point I made is that non-industrialized nations are still poor
even tho they participate in globalization
Yeah the reason they are poor is because of globalization and industrialization
Also social policy lol
Supply and demand curves are poorly demonstrated because this relationship is rarely linear
Esp with growing markets
Equilibrium conditions also shift on a shit ton of factors
Is squeeze theorem the formal name for this theorem?
It's the smoochie theorem
Isn't it "Interference criterion"?
I have no idea what you're talking about
Hi
Hi
oh yo do you guys know what sin does to the x value in sinx idk if they show it in university it’s really cool
like how a calculator approximates it
sine of the angle x in a triangle is ratio of triangle's sides
cordic algorithm
has little to do with what sine is though
wait let me see
is that algorithm an infinite set I think it’s something else
It’s called the Fourier series
Oh maybe not
hi ineed help. the number of comination in (a,b,c) which are all smaller than integer value "n" and greater than 1 , where a,b,c are different to each other is : n * (n-1) * (n-2)

🤣 🤣 🤣 🤣 🤣 🤣
my honest reaction
Can someone just solve the inequality already jeez
tangent of what? you mean the trig function?
by taylor approximation
yeah
i mean the value of it
oh well you know that tan=sin/cos
yeah
so do the taylor series for sin(0)
and divide it by the taylor series for cos(0)
but calculate the values beore dividing
Why use Taylor series what
i dont know he just said thats what its for idk
because it works and this is discussion not help
What's sin(0)? You should just know what that value is if you've studied some basic facts about trig functions
Also #❓how-to-get-help
0
you mean taylor series at 0?
cos 0 is 1 right
or the value of tan(0)?
value
is this a textbook problem? I don't understand
part
limits
ill put a help
its ok

Oh. North Carolina?
nope
Ok.
I might have saw you, who knows?
Oh.-

Yes sir or mam or other.
I interpreted that at first as geometric algebra
Is there a group theory chat?
did you check #groups-rings-fields
Also graph theory
Lmao
How do i know if math as a major is right for me since pre-university math is so much different
Look into undergrad math
did you try asking your math teacher?
math major is fun if you wanna dig deep to understand them all/know more about the wide spectrum of maths
If sectheta + tantheta = 1/k then show that coesectheta = 1+k^2/1-k^2
undergrad math is just a glimpse of what's really happening behind all the math up till high school, and is a good place for you to really choose which field you wanna proceed in

can you read what the bot said
my math teacher hates her job and doesn't seem to like math and she finds it annoying when I want to know more about a certain mathematical concept we're learning about
i wanna do that and maybe even teach math or even do maths research if i am lucky, so i absolutely wanna know more

hi
Hello.😊
Why is it so difficult?
Constructing constraints that are linear with integrality constraints are very complicated and hard to find, always creating extra variables... it's too difficult for me
Ima evacuate to this chat

sadly, yes
Her asking where I was last night is the toughest exam
Given is the following quadratic form
q(x1,x2,x3,x4)=x21 +x2 +x23 +x24 +2x2x3.
(a) Is this quadratic form positive (semi-)definite, negative (semi-)definite or indefinite? Explain briefly.
(b) Find all vectors w⃗ for which q(w⃗) = 0. Explain why you found them all.

Is calculus 3 harder or easier than calc 2?
I would assume easier becuase its about vectors
If you dont know calc yes
Otherwise id say 3 is easier
Parametrization can be hard
But they usually give easy questions
ello
lol
seriously, cuz i see lots of people claiming that the Gaokao is the hardest exam, but there are countries whose students litterally learn calculus, series, complex numbers, algebraic structures and much more just in high school.
which countries do that?
my guess is india
my guess would be some of the first world countries in and around EU
nah
I'd say depends on the person as I've seen both opinions
just like how some people find algebra easier than real analysis and some people find real analysis easier than algebra
it's an individual thing
Isn't that just typical high school topics?
the rest seems so but algebraic structures?
complex numbers tho
Complex numbers are perfectly fine as high school topics
Algebraic structures, I think that one depends.
group theory should be introduced in elementary school
It Also depends on how much are you studying in each of these topics
Well yeah but
I don't think one can realistically teach e.g. cauchy integral formula under the "complex numbers" banner.
complex numbers aren't that complex
I mean go check tunisia national exam or the moroccan one, it's really not something easy to be learned in high school.
seems doable
I am having trouble searching for it, where can I find it?
Search in youtube : "The maths tailor morocco 2023" you'll find a french guy doing a correction.
pdf is in the description I guess
Sorry but I am not going into YouTube to search for this
Shall I send it or what ?
Could you give e.g. a link to a text article with the questionnaires?
Just a second
what's wrong with going to YouTube lol
There are too many low quality vids to risk my eyes and watch history
I see, looks pretty standard to me.
While the basic group axioms are in the test, it does not ask about theoretical questions on group theory
What topic are you talking about
It's definitely not standard for high school nor that hard as well.
Gaokao ? I think it's pretty average compared to this one
Wdym 'pretty average'
Yeah, I mean I'd not say this one is harder, either
Each of them has its own difficulty, in different ways
Also the topics dealt with in the exam are not difficult, most high schools would teach that I think.
It's really not about the topics, it's about the content.
I mean, the content as well - it is not really deep, the level is appropriate for HS level.
I gotta disagree man!
Enough to claim that this is one of the hardest.
Based on what I have seen in Gaokao, I think this one is not particularly harder than that
Though I would not say Gaokao is harder, either.
I also do not think 'One of the hardest' means it is not appropriate.
I have seen some Gaokao tests, and I can tell, it's really about how deep you know about each of the topics you're dealing with. But this one is really something different than that, if you look into the exam carefully you'll see that each question has its own way to be dealt with, and that's what I think is hard about this exam. Definitely not as standard as you thought.
What do you mean by 'each question has its own way to be dealt with'
take a look at the first exercise and you'll understand what I mean
An exercise about limit with lots of hints
I cannot understand what the French portion means, but I think you are simply too intimidated at it
they even gave the derivative for free
tho I don't understand what the question is asking about it
lol, it's not giving the derivative, you need to calculate it
I see it written in question 2
yeah but the question is about proving that the derivative equals the one they've given
easier than just asking you to compute it without showing what it looks like
You could say so.
There are also some tricky questions like the one about the inflection point when n is odd
this looks like a pretty standard exam to me ngl
i guess depending on the rigor they expect
to back the computations
Yeah, that was my impression as well
seems like a solid exam
but it's not torturous like the Gaokao or JEE
need help dm me pls
hello
can u help me?
oh nvm forget it
good to see you again btw @reef carbon 
what adds to make 24 and times to make -36
wait so what ur saying is
x + y = 24, and x * y = -36?
check dms
The base ABCD of the pyramid ABCDM is a trapezoid with a large base AB=a, the Hip BC of

So I’m in Grade 9 Pre-IB, and I just got my grade 10 course selection and I was just wondering what the “m” means at the end? I got two sheets, one being for academic and one being for IB, and math for academic is mpm2d, while on the IB sheet, it says mpm2dm. Will I be in a different class from? I thought that happens in grade 11 when IB actually starts.
hello guys does someone know solving simple economic calculations?

day 137 of hating java, let's go
grinding g+?
what even is the point of wanting to have g+ besides it just being a status symbol
you get access to some new things
its one channel
which are mostly not that useful
isnt it
ah
You get people sending you dms asking for help with dumb stuff
legit happened multiple times to me already
only one of them I even knew beforehand
"please verify my proof of the collatz conjecture"
What's better than grad+ is putting "phd student" in your about me because people think that means i have a phd instead of thinking im studying for one
im not even a grad student yet but people keep dming for their math help
wow, you have a phd but still go to university to study
Well, i'm working on my 4th phd.
This one is going to be in generalized googology and inaccessible power towers
Being real i work on fluid PDEs (but the pure side, no numerics)
They come up fairly often, though idk the abstract semigroup theory yet as much as I should
I wrote my master thesis on irreducible C_0-semigroups
I don't know much about the concrete PDEs 😄
Oh cool, I should definitely read some more. Before I got into PDEs I was mostly into operator theory and dynamics so I think I would like that stuff, based on the few talks ive seen
It's definitely a bubble of people who think very strangely about math, IDK if ill do it forever but I think im kinda mired in it for the PhD
Because of departmental focus
And I definitely dont mind having a physics bent to what im doing
that does always irk me
not that I don't like doing what I'm doing
but the reasons do
Yeah
I mean im lucky to be in a place with huge diversity of interests within analysis, so that's good
Are you in a phd program right now?
just starting
From what I understand PhDs in europe can either be applying with a particular advisor or applying to a department
well I do have a specific advisorr
but there is still the formal process through the university
Whereas in the US since the masters gets folded in there's a lot of flexibility of topic
I see
the formal process is kind of a sham tho
But maybe you have some room to pick a direction within your broader area it sounds
yes, it will take a bit to crystallize out
pretty cool
true it's pretty cool but not like public static void string args in java
I like js more than java
Well, ts is better than js
just for autocompletion
yeye
I like java but it's so slow
#help-16 message
@hollow ravine sorry i didn't catch you earlier, but tyvm for the keywords, i'll look into these
thats java btw
it looks hard
I'm considering getting a framework laptop
use proper package structuring
the gameplay itself tho, it looks like a challenging game
Even though it looks rough, to make this game in java is an accomplisment worth being proud off, did you use any external gaming libraries?
I did
looks like you've never played geometry dash before lmao
I used jframes
Even i have been programming in java for more than a year, i never tried to make anything more complex than a command line app, i should get out of my confort zone a bit.
hmm, seems fun, though am not sure of the java gaming landscape, what is considered to be the go to gaming library is a mystry to me.
I don't even know what library ive used because all i do i see my teacher's example and then start doing mine
Not projects per say, more like exercises, all command line apps, boring as f
I actaully made one like a month ago, i don't know how to use it one bit though, i just made it so that i could log into a site.
right now, i focus more on my studies than software engineering, am sure i can pick everything related to making software after i have some free time and am free from this laborious studying hell.
those ones are indeed boring and easy to do
especially it gets harder if you try write a code on paper because you can't think if you have errors while writing your code on paper
I've done my first project before starting my final project
it was arkanoid game
you didn't
you just put everything in the default package
furthermore you should use a build tool like gradle instead of relying on IntelliJs system
Those were my programming exams, the "guess the output" questions were the worst.
It got even worse with data structures, man every damn pen and paper programming question required so much deliberation, you needed to think up a plan of how you gonna procced because if you didn't you would be screwed when you inevitably have to deal with some complications with the solution.
And now you had to deal with all possible edge cases, those were troublesome to deal with.
and the "guess the output" question now where on overdrive, they where incomprehensible, man i freaking hated those the most, you needed to turn into a human debugger capable of reading the most BS code imaginable.
lmfao
also look at the first project I did (it was terrible)
and i used drjava

will, am proud at least that am able to understand the jest of it
though that way you made bricks, you could have used Random object to randomize the color of each brick
also why is it flashing so much?
yeah idk
I didn't have enough time figuring out how do I fix it
it's joever
it is just me or it could be the drjava editor? because I found drjava sucks
pro that is the first time i heard of such an IDE
for java it's eclipse of intellij (the king of java IDE's)
or if you are feeling esoteric, you could use vs code
I tried copying the code from IntelliJ editor to drjava and it didn't work at school pc
so I told my parents to bring their laptop cuz the school pc one always have permission to administrator
probably something to do with different versions of the java JDK.
hmmm
though am not sure.
