if I hear smth funny my friend said I just remember it bc bro said it irl
Bro I’ve TALKED to my friends through my status
We talked to each other through statuses
this crazy bro
I’m not surprised this happened
Much worse was done to talk
Discord flopped withh this one 🥀
I’ve used a base 64 encoder to talk to my friend on a server
Do yk Trello
They will never know
Nope
It’s like an organization site I used for a server and
One time my friend got grounded
And they couldn’t use Discord or anything
So they talked to me through there
😭
This is just so funny and dumb at the same time
I would probably use slack since people consider it “work”
yes
what tha hail
Omg ew not Slack
I don’t like thinking about it 💔 Reminds me about having a j*b..
hey can we sync about <topic> rq
<link to zoom>
I'm working on <JIRA ticket>, are you using the test env rn? I want to deploy to it
My TAs pissed me off this semester because finding theirzoom link for office hours was a scavenger hunt 🥀
lol
do you live on west coast
My dream is to not work
I’m in the CST time zone
I want to work on my dream
That’s the most I’ll say
EST
CST is better
It’s the Correct Standard Time

ok vro
Hi my favorite mathcordian
Your reminder for today
Me too but at the same time I don’t want to
how're you holding up?
I'm a little tired, a little anxious, a little sad, but I'd still say that it's going okay :>

If only I was the community notes guy
Yes I meant like
Nothing crazy is going on in my life rn that’s of concern
I’m sorry, I hope you feel better
I’m always here for you
I know I know, but that didn't tell me how you're feeling this very moment 
'ppreciate it, but don't forget that it goes both ways c:
I will give you both
if accepted
I feel hungry because ig I didn’t eat enough at 5 PM xD
But I can’t go grab smth light rn
I’m back again… is there something wrong rn?
My mom gets pissed any time she sees me up in the kitchen late
For “religious” reasons
No
Yes pwease

ah, I see 
Cat and bunny hug is crazy cute
I love seeing diff animals be besties with each other
😭
If only humans could learn from this shit and not be bigoted towards people who are different from them .. 🥀
I guess bro
Oil and water imulsion
??? @moderatoes I find this extremely disrespectful and unsuitable for a fiscussy 2 user. Please take nessesary actions


I suppose it's some kind of quality-conservation principle, when #discussion becomes interesting, #serious-discussion becomes a cesspit
blame lockie cuh
this one's done by them
hello everyone
happy birthday
not sure whose birthday it is but happy birthday
happy birthday
equinaurx (see bio) and it's also metal's birthday
Happy birthday
thank you everyone !! sorry i was drawing LOL
hello i have a fr question
extra #fr because its 2 am
are/were u broke broke in grad school
is that normal
like
when i was first looking into programs, the stipends were around 35-40k so i assumed that was the standard 😭
im rechecking some (i applied to) and theyre like half that!!
Yeah it can vary quite a bit
idk it depends a lot on the location, too, my grad school's in germany
i dont think he wants to talk
oh ok
this manifold guy does
the fake one
Nice: )
like a fake R^4 
i think you last said what it formally was? I cannot find the comment
like a fake S^3 you mean
let's decompose that statement
S^5 lives in R6
fake glome 
here’s the definition given in Pugh:
A cut in Q is a pair of subsets A, B of Q such that:
(a) A U B = Q, and A and B are disjoint and nonempty (i.e. A and B are a partition of Q)
(b) If a in A and b in B, then a < b
(c) A contains no largest element
jargon
the definition HChan gave is essentially that of A (the other set B is determined from A, so it’s not strictly needed to be mentioned)
im trying to avoid talking about sup and inf lol
from (a), can we say that A and B are right next to eachother?
if it is, it would make sense why it's called a "cut"
I’d say it’s from (a) and (b)
yes, you are quite literally cutting the rationals down some point
and defining a real number as the bottom half of that cut
that's why it is called a cut
ok. i like that you included (b), because it's making me think. Is (b) necessary?
it is necessary to remove duplicates
if a in A and b in Q? shouldn't it be b in B?
so for example there’s A = {p/q | p/q <= 0 or (p/q > 0 and (p/q)^2 < 2)} and B = {p/q | p/q > 0 and (p/q)^2 > 2}
yes, my bad
npnp
I had just come across an exercise in analysis asking for a proof of this (or something similar? I'm not sure if it is identical because:) for the reals but not the rationals
actually i thought those 2 statements were equivalent, not?
property (b) is meant to encode that A is completely to the left of B
if a in A and b in Q, then you can pick some b in Q that is less than a
fair
i see. I just thought the fact that saying they're disjoint from (a) was enough for that
I think maybe it would be easier to describe the cut property as two nonempty, disjoint subsets A and B, with A U B = Q (or R), and a < b for all a in A and b in B
nevermind, i take it back. I see what you mean
yeah because otherwise they could be disjoint but all mixed up alternating back and forth
I don’t think we can say A U B = R, because we’re looking to construct R from Q
how did we get (or R)? Is this what someone was talking about when they gave the sqrt2 example?
this pair of sets essentially uniquely specifies sqrt(2) using only rational numbers
by having the cut exactly at rt2?
the definition I stated is a property of the reals, so since you're specifically talking about Q and constructing R from it, then yeah that would not work as well
yup. It’s larger than everything in A, but smaller than everything in B
Ok, this get's us one irrational number, but how does it guarantee that we can do it for all irrationals? Because I notice that it wouldn't work for something like pi
why wouldn't it work for pi?
because pi isn't the root of a rational number
not just square root, any rational root
well, that just means that you cannot explicitly describe what the cut looks like
but it is in there somewhere
except you can in this specific example.
just like how you can't actually describe most real numbers but there are still there somewhere
it’s less obvious how to express pi in this way, because we aren’t allowed to just use the pi symbol to make the cuts
there are multiple monotone series for pi.
unless we’ve defined pi elsewhere already somehow
yeah, most conventional definitions for pi employ the use of sine and cosine
which need the real numbers to work
any series definition would be somewhat unconventional
...........
it works but this goes against the sprit of the question
indeedddddd
i'm a bit confused on how it works
can you tell me what you understand a dedekind cut to be?
from what I understand: of a set Q, a dedekind cut is the element of Q \ A \ B, where A and B follow the properties we discussed
just seeing this, thank you! 
can you spell them out for me?
A and B don't share any elements. Every element in A is less than every element in B
am i missing anything? this is how i understand it
almost, except Q \ A \ B is empty
wow. This one is interesting
the cut is the pair A and B itself
it sounds like root 2 shouldn't exist then
it did not exist before the construction.
does not matter
I’m following Pugh where he takes it to be both, but from what I understand we could equally well take either one by itself, since the other is uniquely determined from it
I'm trying to make it easier to understand
if we derive rt2 with the property that it shouldn't exist, i'm not understanding how it exists after the construction
but since you're confident that you can do it then i will take my leave, enjoy
rt2 isn't in either set, and Q \ A \ B is empty, right?
well, next you need to learn how to do arithmetic with these cuts
and once that’s done, you can prove the square of this cut equals 2
why? Multiple brains produce better results
money does not actually have value. it is just a piece of paper, and yet we can do reasoning and calculation about it. why is that?
it is annoying me that people are responding to my comments with um actuallys
so ill leave for a cleaner chat
i hope you all have a good day
who did tha
.
i don't think he did it with that intention
it's fine, I'm done with this
as I said have a nice day, feel free to ping me any other time
cool
peace 🕊️
uhm
BACK TO TOPIC
we need more people for discussion
ill go recruit some from math discussy
how do we do arithmetic?
so, the definition of a cut is quite elegant, but this is where things get messy
What are the rational numbers? Just any number that’s not irrational nor complex?
eh, maybe it’s not so bad
A number is rational if it is equal to a/b where a and b are integers and b≠0
yes! so like 2/3 or 5/6
So, a ratio of two integers
(that's why they are called rational)
no wai
Omg
A number is irrational if it cannot be represented as a ratio of two integers
One example is √2
where the integers are coprime
if x = A|B (this is Pugh’s notation of the cut A and B), and y = C|D, then:
x + y = E|F where
E = {r in Q | for some a in A and c in C, r = a + c}
F = the rest of Q
that’s the definition of a sum of cuts
coprimality is sometimes optional, which is why the proof of sqrt(2) being irrational usually has it as a separate assumption
i think you're right, but it almost has no harm in assuming it in everycase, it would get rid of multiple representations of the same number
oh I'm not saying it's harmful in any way
but then again, in the spirit of making as least assumptions as possible, maybe not having it is better
it's just that usually it's not specified
unless coprimality is important in a context involving Q
Heres this funny proof of cube root of 2 being irrational. Suppose the cube root of two is rational. So 2^(1/3)=a/b where a and b are integers. And b≠0. Cubing both sides we get 2=a³/b³
So a³=2b³
a³=b³+b³. Do you see the contradiction?
never seen the proof here, but isn't this fermat's last conjecture?
theorem, i guess.
Yeah, this contradicts fermat's last theorem
using a hydrogen bomb to take out a mosquito 
I wonder if there’s any hidden circularity in that
I really hope not
I would have no chance of finding that
sorry for diverging from the arithmetic. My attention is back to the definition
Im NOT gonna look at the proof of fermat's last theorem
haha yeah, no
there’s a very nice short proof that the nth root of m is irrational whenever m is not a perfect nth power of an integer
it relies on the fundamental theorem of arithmetic
you consider a rational number p/q and express the numerator and denominator uniquely factored into primes
and cancel any common factors
then consider raising it to the nth power
this just copies your primes, and no new cancellations are possible
so this is very much intuitive. Just as you take the sum of any number (assuming you have already constructed the reals)
so it can’t be an integer since there’s stuff in the bottom that doesnt cancel
yeah, take all possible sums from A and C. It makes sense
multiplication is a bit worse because you have to worry about signs
Doesn't this mean that the new cut E|F doesn't preserve the property that E and F have: every e in E is less than every f in F?
it should still
E should take the form (-infty, r) intersect Q
and then F is (r, infty) intersect Q
and x + y is r
dedekind was gauss' student, right?
good question, not sure
I remember reading that on wikipedia
apparently he was Gauss’ last student
wow. Last was a blast
no cap
i will ask about the pi thing at the math village thing I will go to though. It still bothers me a little
i'm guessing we will discuss dedekind cuts since the name of the workshop is "real numbers"
or "Reel sayılar" in turkish
I think this is all my time (and maybe yours too) permits me to talk. I really enjoyed your company. I hope the conversation benefitted you, which it should. Of course it also benefitted me
yeah, it was fun!
I hope to see you around. I may come back later today or even another day
I know what you mean about pi
: )
I chat here a lot so I’m sure you’ll see me around
This man is the manifold madman
haha, wassup Tiny
what were we talking about last night…
oh, groups
that was good
you can do it! though I must say, having studied it a fair amount, I can’t say I truly know them
there’s a ridiculous amount of depth hidden in those axioms
but the more you learn the more interesting it gets
have you studied any set theory? just basics like unions, intersections, and how to notate them
Yes,”How to prove it” studies some set theory along the way,and I’ve been studying that book
So far it’s gone up to families of sets and their operations,aswell as power sets
One of the chapters close to the end are about cardinality and ordinality,and/or counting if I remember correctly
I look it up every now and then just to take a gander at higher mathematics

@torpid bay Do you want to help me make thing thingy into an integral?
meow
Me studying for a physics final
🤭 it's definitely like that for some exams
Hello ladies
what r u, the guy from old spice
im using khan academy to prem myself for trig within 4 weeks, should i use something else or am i taking the right path?
Aight, ima ask something. I'm self studying linear algebra, and it's TOUGH. Everytime I feel like I understand something and feel like the concepts are getting easier and I can coast a little, the following concepts get harder and harder.
It constantly checks my progress speed, and every time I think I can speed up now that I get concept X, the textbook keeps giving new topics that stall me. It's hard to keep up with any reasonable completion schedule when this happens, and it's really demotivating.
Anyone have thoughts and opinions on this? Whether this is normal/How to speed it up/how to not be demotivated?
reposting here since #discussion was busy
It's impossible to get to a spot where you just coast because then you rapidly move to a spot where you struggle
And while you're coasting you're not learning so that's a good thing
I get it... but it's requiring all of my brain power from the absolute start. It's tiring, and I can't imagine that someone keeps doing this for 3-4 months for an entire course like this....
I guess I want to know if this is really that normal. I don't think I'm keeping ace with the recommended schedule of the course even because I'm having to explore so many practice problems to understand it completely lol
strang is probably a little more numerical calculation focused
idk if that is what you want or not
are you used to not struggling like in highschool level topics?
LMFAOOOO
i did the same thing before cuz bro was expect me to memorize stuff
LITERALLY 💔 cumulative finals are so ass fr
frfr
my preference would be a newer text by meckes/meckes designed for first course in LA for math majors (not eng). However that may or may not be better for you depending on whether a rigour focus helps you learn or not.
yeah, i never had problems in high school. single var diff and integral calc was easy, so was stats.
possibly you are not used to not being throttled by the clss being slowed down for the pace to fit all students
you are probably also overestimatinhg how much the avg person who makes it thru a basic LA class understands all the material
but its immensely better for you to not be throttled
lmao that's... one way to say it.
I guess I'm doing it slightly as a preparation for machine learning studies for bioinformatics, but I am also going to have to know some rigor since a lot of machine learning methods in new fields (like bioinformatics) require intensive proofs. You can't get any new methodology published or accepted without a reasonable amount of mathematical analysis, interpretability, and proofs.
so having rigor and the application related background is kinda... both important?

personally i just returned from a long time away from mathematics (in industry) and am trying to self learn some stuff after forgetting like 90% of what i knew and its not uncommon for me to be stuck on a page for a day
(i am a bioinformatician by training)
Alright... if that's how it is, that's how it is I guess. I just never imagined that students metaphorically climb a 45 degree incline for 3 months at a stretch every day.
Having the reference frame that this difficulty is normal gives me enough confidence to stick around for it.
its especially true if youre trying to make sure you understand the material vs able to pass a test by memorizing some rules and blindly applying them the same way you did on the practice problems
If I have to continue my work in publishing ML proofs, I kinda have to understand the material lol.
yep
a lot of these texts also have a ton of exercises with the assumption that the professor will choose which ones are good for the way theyu are teaching the material, which can suck if youre on your own
because its harder to choose yourself which ones should be done
but it's definintely slowing my pace down compared to what the avg uni student would do.
thats also where a well varied amount of potentially more difficult exercises can be good (one of the reasons i recommend meckes/meckes over strang)
what did you mean by this?
doing 5 deep exercises could be more enligthening than doing 20 small ones
but yeah. doing all of them good. youll be doing way more than a normal student does though
there are some books that interspere the exercises with the text instead of the standard "end of chapter" which is sooo nice
I actually made the mistake of starting with Hubbard and Hubbard
That shit was sooooo abstract that each page was taking me 3 days
I have a copy of it from honors linalg from when I was in college
Ill try meckes
doesnt hurt to have a secondary text to read up on concepts you are confused on anyhow
I have realized this to be true more and more. Having 2-3 textbooks on a topic actually helps a bunch
thanks for the reassurance @rigid geyser
hi
can someone further explain why gojos limitless applies zenos paradox?
it is something im interested in explaining to other people
if someone could answer this, that would be great.
-thank you.
uh ok. doesnt really seem to answer my question
uhhh. doesnt seem to answer my question 🤔
Poor ants
can someone elaborate zenos paradox to gojos limitless technique??
i want to further my understanding and help explain it to other people
expand your domain
No, because powerscaling random anime characters is utterly stupid
What sort of explanation to do you want
this isnt an anime fight im trying to explain. just trying to get some people to help. hoping someone can answer my question tying in zenos paradox
It's a piece of fiction
Does anyone like Sam and Colby? And reading? (React with '❣️' if yes)
Yes but gojo's domain expansion is fiction
im not talking about the domain bro. im talking about "limitless"
im sort of confused how zenos paradox applies to this and want to further my understanding on it
Anyways
Based on some cursory searches online about gojo and whatever
So
Zeno's paradox is the idea that you can never reach a target because you can always subdivide the remaining distance into whatever right
It doesn't actually apply in reality because the shorter one of these remaining subsections is the shorter the time needed to traverse it
Blah blah blah convergent series
Jujutsu kaisen fandom site says ```Infinity (無限 Mugen?) is the base state of the Limitless and is essentially the power to stop.[4] The Limitless technique operates the same way convergent and divergent sequences do in mathematics. The Infinity is the convergence of an immeasurable series, anything that approaches the infinity slows down and never reaches the user.[5] This is because the technique takes the finite amount of space between the two subjects and divides it an infinite amount of times.[6]
In mathematics, no matter how many times someone divides a number it will never be reduced to zero. Instead, they will be left with fractional units so infinitesimal it would become immeasurable to their eye. The Limitless brings this concept into reality, so anything that attempts to penetrate this infinitely divided space will slow down to the point of appearing to stop completely.[7] ```
So if we want to say that this modifies reality so that zeno's paradox applies somehow
so you are saying that motion doesnt exist in that world which is why you said it is a piece of fiction
One way to do it would be to have each remaining subsection of distance to be traversed take a fixed amount of time
Limitless technique, hollow purple
So like
in that way, it appears the projectile is stopped
Let's say you can move with speed 1
And want to travel a distance of 1
Zeno's paradox would break this up into a distance of 0.9 and a distance of 0.09 and a distance of 0.009 and so on
it would be graphed as an ASYMPTOTE
And traversing these would take 0.9 time and 0.09 time and 0.009 time and so on
But if you say that each subsection takes 1 time
Then the amount of time needed to get somewhere will be infinite
then if you had unlimited time to reach gojo, gojo would be the limit
i assume right?
also thanks for the explanation
watching vids, reading books, doing exercises, and occasionally asking here
this depends on what you know and what you want to learn, there's a ton
I'll repost smth I told another user 
Zeno must have been smoking weed or something
tyyy All of this is practice, do any of you find ways to apply math before you learn it?
it can be helpful to understand where certain things apply I suppose, and there's usually a great job out there if you search "{topic} applications"
yeah I like reading about applications, though I kinda study in parallel to doing that
recently I was a TA for functional analysis and I also tried to focus in applications where possible
it appears in things like PDE, optimization
for more basic stuff like calc and ODE I also do try to relate that to concrete situations
books that aren't like, pure math oriented often have a ton of exercises inspired in application
how long have you been doing maths for do i have to have a lot of experience
a lot of experience to do what
master a topic of choice
depends on the topic and how fast you learn
everyone's at a different spot in learning, if you don't have a lot of "experience" you simply study the basics like calculus or maybe Book of Proof I linked above if you want to do proofs
personally I've been studying uni math for some years, currently first year PhD
I personally have decent experience with algebra and differential calculus, but only a few months into anything above calculus
what is your goal? why do you want to study math specifically, knowing that might help to give better recommendations
integral and multivariable calculus
like, what do you envision you using math for?
physics
cool
where are you in your learning journey?
i dont know
as in, what math have you learnt?
I take my own notes based on books or lectures, then spend some time doing exercises from books, that's like the basic loop for each chapter lol
studying in groups or explaining things to other people also helps a lot, if you can proficiently explain a topic to someone else then you've mastered it
and math can be a very social activity even if ppl don't often imagine it as such
What lectures do you do
Thanks so much 🙂
I meant my uni's lectures from when I was in undergrad, you can also find lectures in YouTube
there's a math for physics course in my uni where you essentially cover all the topics relevant for physics (which are usually covered in a full undergrad math study programme) but crammed into a single semester and only at the surface level 
or in specific universities' pages like MIT Open CourseWare
also for this I would recommend Stewart's Calculus, and maybe Marsden-Tromba's Vector Calculus
ofc there's a lot of other books for these subjects specifically
I would say, Thomas over Stewart though
also covered fairly well in Paul's notes here
Woww tank yo so much i never knew about this
Thomas seems to provide a little more rigor from what I have seen so far (I do have both and work through both)
btw if Sofa is looking for an algebra book as well (since Idk where Sofa is in her learning journey), consider College Algebra and Trigonometry by Lial et al.
quite a lot of real-life motivated problems

Hi
why is there only “yes” to being a weeb 😭
It's a nessasary quota
Please don't remind me of bad data collected in labs 💔
Hi
for bad data collected in lab I'd just be like "yeah these are irrelevant" which ended up erasing 90% of the data
mamma mia
just to get that stupid line of best fit
Biology majors when it comes to mess with the obtained data to get a straight line ( but the empirical equation represents y=kx²)
One time there was a group that I kid you not got perfectly precise results (0% error..it was literally the same) and the TA made them intentionally mess up their data so they could discuss experimental error 😭
for a second I thought you were achooeus
You have 2 choice's save your 3 elder's or save 1 child what would u pick and why? Would u rather choose 3 lives over 1 or choose a child that has a beginning life story over 3 lives.
3 elder woman so I can be introduced to their families and acquire a child to replace the one that died
Mfs will claim they're sum johan liebert but they learnt dark physiology from booktok
What if that child was your brother almond?
I'm sorry but I dislike questions like these
same strategy bc I am a sociopath
your lab grade had a big factor on who is your TA
well the lab coordinator really
tfw my chem lab coordinator was the one person everyone hated in the department
No one likes any of the general chemistry professors here
I'd rather do some combinatorics problem
why did you react to your own comment bro
Only a couple of them are good
I just hate that we're forced to pick one
I'm not going to sit and decide who's life is worth more lol
Regardless of whether they are close to me or not, or whether they are younger or older

<@&268886789983436800> self-promotion
this isnt the place to promote your youtube channel, thanks
I need 500 views that’s it
Dude I can get reward for that
So please atleast watch it
regardless, this isnt the place for it
Well which channel does it
none of them
🤦
sorry, youll have to look elsewhere
500 views is not too much anyways
thats the spirit
Then you should be able to get them without spamming random servers!
See yah
just watch it 500 times yourself
If I have 500 accounts 😂
fwiw there are people who do this (those who know
)
🤣🤣 I’m not that unemployed
yeah good response 
K see ya
@versed jungle
Is not this type of person
but he does have many alts 
I'm hungry
Eat fuuud
Damn
i tried doing that for a friend's video
and gave up after about 5 accounts
Hey
Meow
Why?
Im a cat
Nya!
That's very commendable
Thank you.
im convinced the former gifted kid stereotype "trying new things and quitting them when they don't come easily to you" is the result of former gifted kids trying new stuff at a higher rate and that mostly positive feedback at early stages in training is pretty much necessary and hard to find
First stage is for children which is an obvious difference but I don't think it changes much for adults. (also its talking about sport but i think the three stages apply to nonsport)
To understand my worldview better, I say if you're trying something new and have the choice between getting mostly positive feedback and getting real, harsh feedback, you would be better off getting mostly positive feedback until you have some level of competence where the "real" feedback is not too demotivating.
I'd love to hear other people's thoughts on this.
I can attest that the stereotype is definitely real
I know somebody who would definitely be considered gifted who like isn't even willing to try basically anything new over a fear of being bad at it (like chess, certain games, etc) (being bad as in, not immediately very good without practice)
behaviour reinforcement
there are ways to get rid of the fear emotion gradually
I only know of one

Nya!
Heyy does anyone know why the graph of b²-4ac is true for predicting if the equation is always positive or negative
like does it have a proof or we infer from seeing the results when we tried it to see its sign
it comes directly from the quadratic formula
the number of solutions to ax^2 + bx + c = 0 is the number of times ax^2 + bx + c can switch signs
Hi ola
Nothing much u
It's been great wbu
Ok great
Btw where are you from
what are you doing?
Are you from Nigeria
I wish I could tell you!
I am watching film
No actually, I don't wanna tell you
Y Can't u tell me
U want to tell me in Private
Only half seriously, after a certain point in progression all feedback is harmful
All external feedback maybe?
What I don't get
Oh sry
don't pretend to be unknowing of the scheme
What?
It's as visible as the june sun
Ok
please dont pressure people into revealing personal information
I am not u are getting me weong
is there a word for the class of complex numbers z s.t. |z|=1? the ones that can be written as e^ix?
yeah it's the unit circle in the complex plane
I think this person's an alt of the racist person
that was banned for a day recently
???
i would reserve roots of unity for the ones with a rational [multiple of pi] argument
@obtuse grail this account
DM @polar panther with any evidence of this
sorry, I wanna let the account some slack
not sure what is going on but this user used to dm me randomly
im surprised they still talk here
but, I just warned you in advance
this kinda explains
The account was made in the summer of this year
ignore the account
they only dm active people or random ppl in here
yea
campus being closed till after new years day is killing me
I need big boards to write on
Isn’t that what winter break is meant to be?
winter break is my opportunity to catch up so I can seem smart lol
that actually makes sense, good use of the break lol
well to be honest, I also do a lot better just reading and working up to things myself than going to classes
thats a good skill to have
trying to find a good way to put it. Class moves both too slow and too quick for me lol
true
Does anyone know what pre-requisites do I need to be able to understand what all of this is saying? I really want to be able to delve into this and I was under the assumption that you can read this without much knowledge but it seems really hard to me.
youll be able to understand the statements (at face value) if you take any intro proofs or discrete math course. but to really appreciate set theory youll probably need a bit of mathematical maturity.
Tysm!
OK, but can you attest whether the stereotype is real for the reason I mentioned or for another reason? i.e. do other people try stuff at the same rate as them?
I dont think thats the reason, but I'm not them so I can't say for sure
We got irl presidential yaoi before gta 6 🥀

@short acorn regarding one-to-one for question 31,
,align
&\text{If }m_1+n_1 > m_2+n_2\text{, then:}\\
f(m_1,n_1) &> \frac{(m_1+n_1-2)(m_1+n_1-1)}{2}\
&\geq \frac{((m_2+n_2+1)-2)((m_2+n_2+1)-1)}{2}\
&= \frac{(m_2+n_2-2)(m_2+n_2-1)}{2} + m_2 + n_2 - 1\
&\geq f(m_2, n_2)\\\
&\text{Thus } f(m_1,n_1) = f(m_2,n_2) \implies m_1+n_1 = m_2+n_2
Axe
ooo because they're positive integers
That's nice
Saved
yeah it uses the fact that m1, n2, m2 and n2 are positive integers in multiple places
for example, it's used to say that m1 + n1 >= m2 + n2 + 1
and this is used to make a substitution in one of the steps
@short acorn there is intuition for it:
f is going down each diagonal from left to right. first (1,1), then the diagonal along y=3-x, then y=4-x, and so on.
now m+n is different for each diagonal. so if m1+n1 > m2+n2, then they should be on different diagonals.
then we should have f(m1,n1) > the rightmost point on the previous diagonal, which should be greater or equal to the right most point on (m2,n2)'s diagonal, which should be greater or equal to f(m2,n2).
and indeed following this reasoning, the algebra went through successfully
What are we tb

Create a help channel, and I'll have a look.
Nah I’ll just reply here
!help

How did u do the bicen maths videos
You shouldn't take up a discussion channel when wanting help
I created a list of chapters I wanted to master for the week, and then watched all of them in his playlists. After studying a chapter from his channel, I would try to find past paper questions on PMT to complete. If I struggled on a question, I'd just study that certain topic, not the entire chapter.
I’ve done the papers but every now and then I get stuck on these random questions
Like tn it’s mainly some 3D vectors/planes
You've probably not studied them properly in depth and practise, if you're forgetting how to answer certain questions from a topic from time to time then that shows you haven't fully mastered the chapter. I suggest you restudy the chapter from his channel, create notes, then attempt some PMT and past paper questions.
Ok
Also one last question
do u have an alt in revision server
If you're still struggling, then you can send me some of the questions and I'll guide you through them.
Thanks
No, I have already spoken about this.
Nah it’s just there are some new things which make me believe u have an alt there
But anyways it doesn’t rlly matter
?
@frank sequoia
is there a reason why we write e^ix instead of e^xi?
For real numbers i say, to have more clarity
I feel like the convention is literals then constants then variables within a single string of multiplied terms
The kissing number of a polygonal concave shape that's symmetric along the x and y axis can reach higher than 6, right? If so, I can't find or think of an example 🙁
New pfp waw
Only for this server, I still have the other one as my universal pfp.. but I might switch back to having it in here
I'm indecisive 
can you edit server nick
Yes
Your main pfp is really cute, although I forgot where it's from
cool
Thank you!!
I don't know where it's from
:p
@bold citrus
did you get off pinterest
oh this is taken too
Yes
yo
y’all mind if we hijack your channel to talk some maths?
yes! i hate math!
You can just have two concurrent conversations
Nobody owns the channel
if you’re ok with that!
nah talk yo math son
thank you :)
I thought your message in #math-discussion was telling the spammy kids to go to discussy 😅
y everyone get pfp from pinterest
@bold citrus okay so ‘solving’ a differential equation means finding the function(s) that satisfy the equation, that make it true
so for example let’s say some special system is modeled by the equation y’ = y
‘solving’ that equation means finding the function y(t) such that its own derivative equals itself
can you think of a fnctn whose derivative is itself?
😠 milk make my tummy hurt
ping me when you see this ad
ooh ooh I know
go for it
i was catching up haha but yeah e^x
laplace goes crazy
we can do better than e^x
take y = Ce^x, where C is a constant real number
when I differentiate the constant is unaffected, so my solution can actually be any function of the form Ce^x
e^x, 2e^x, … all work
i see
do you know about pdes? ;)
I got stuff to do I gotta go now lols
but I hope I could make that make sense to you
differential equations model systems
a lot of the time, each term in a differential equation will actually correspond to some physical behavior of the system
somewhat
we can solve differential equations to find a function which models the behavior of the system we were describing with our differential equation
for example, that motion equation I gave you describes … well, motion
so the entirety of the system can be described with oen function>? or are we just finding a function that describes the specfic part of the diffeq we are targeting?
so the solution describes how the system moves
in this case ‘system’ is a specific particle
the latter!!
but you know the great part?
a lot of systems are essentially parameterized by just a few variables
you can come up with a system of differential equations by describing the behavior of each of those variables (coming up with a differential equation with each variable in it)
Hi feather, long time no see again
and so you can fully describe the system by solving that system and arriving at solutions for both
(or more)
hi! I actually have to make my way out soon, but nice seeing you too!!!
great microlecture, TA feather

guys why cant i change my per server nickname😞
personally i think hype moments and aura generating function is a really cool username
nicnname*
you can DM @polar panther to request a nickname change
No matter what your gender is, it's time to man up and stick to your new years resolutions
On average, how many people actually do that 💀
Probably like 1%
Source I made it up
My new years resolution is to not change a thing.
Well, they did a bunch of studies about this, what most concluded with was that you cannot expect to change your whole lifestyle in week lol. Hence why people start out slow losing weight by either drinking more water or eating healthier rather than just going straight to the gym and doing all the life hacks.
Often the resolution is too vague too.
good rename
i agree
I thought they created a new discussion for a second
Why are the other 2024 discussion channels hidden from me
And the negative 2024 channels as well
You can't forget about the negative ones
People are renaming discussion channels now
did you guys know that 2026 isnt prime
i hate leaving a year with a number that has cool math facts
Oooooo, but 2025 is because it can be divided by 5
How?
Ah, 2026 isn't prime because dividing it by 2 gives 1013 which is only divisible by 1.
happ new year!!
it doesnt matter what u get when u divide by 2
Happy new year!
20 mins late lmao
obv even => not prime
why?
being divisible by 2 alone is enough for it to be not prime
Interesting
How about 2030?
i think we should re check - what is the definition of being prime?





it's good.
