its from amc
yeah algebra and basic geometry is the starting line
maybe some number theory
isn't it aime?
alr then
hmmm
huh
<@&268886789983436800>
it still appears to be too tedious for 60 seconds
oh it isn't
tan is increasing from 75 to 90 and we get that AX s 1+sqrt3/2 so we just have to keep doing (1/2+n)/(1+sqrt3/2)__>__2+sqrt3
so we get n__>__3+2sqrt3 which is less than 7 but greater than 6 so it is at minimum 7
thank you genis
genius
I will NOT be able to do this in 60s but iz possible
theres a clever trick i come to know now if you consider A new rectangle as right angled at A, the base is the hypotenuse ( let length be l)
cos75 = AB/l
l= AB/ cos75
as soon as l > AB/ cos75 the angle becomes > 90
huh
okkie now make ricardio spawn
RICARDIO
ricardio
hi hi
wazzupp
huh
why is this relatable
theyd be crashing out
true
many ppl
well like i odnt personally know

Hiya friend!
Hallo
hi
Hru friend?
good hbu
Good, ty for asking friend
I have a cntest on teusday and I'm so fried
what do you guys use to study for math competitions? I use youtube and aops textbooks to study, but its not really useful.
past papers and books
ya np
And also an actual mentor
im poor
goodluck with that
seriously, you're in disadvantage when you can't not afford books or mentor
ill try to buy some books. thanks for the advice.
You should ask people recommendations about books before buying one, especially those who have participated in the same competition
okay
also do the past contests like cupcake said
it rlly helpd a lot with understanding the format and question types
also what contest r u doing
hi birdy
I’m currently studying for ARML if you know what that is
hi birdy
hi zelix
what is UIL even about bro
@inland totem did u do amc
ye
i did all 25 on amc 8
i thought u missed dedline
and i did amc 10 once
oh
also did all of the qs
i thought u got a great score on aime
what score did ya get
23 on amc 8
hehheheh
u got a 3 on aime
15 problems?
NOOOOO
imma keep it there
NOOOOOOOO
hehe
O
NOOOOOOOOOO
I was surprised there was a bit of trig for amc
guys i sillied 6q's on aime dont blame me
yea
aww
hmm
what
Thanks
never
zelix is in imo
yeaa
orz
rlly
very orz
orz
yea he got 45/42 on jmo guys
fr?
orz
orzzzz
potential is like jmo at 10
RIP imo
aint no shi have potential then
potential is proving gravity at birth
hmmmm
yes
lol
theres still other stuff than math
math is not the only path in life
REAL
he's in chem olympiad too i think
orz
he's beyond orz
Ok enough glaze
yesss
never enough
Im sure he prefers to live a humble life
going outside is fun
beep boop
it is fun tho
Ok
did amc8 get easier ts year or smth
yes and i sold
i could've got 25
but my ass sillied 2 questions
hmhm
oof
i sillied one
that my non-math classmate got right
hmmmm
is getting top 6 for my province in the comc tuff?
orz
fr
bernice macnaughton sounds like a good school
and congratsss
tyty
lowk ii might go there
im only gr 8 so i dont ahve much to worry 😄
orz orz orz
also aren't u leaking ur name
i mean its fine w/ me
wat was ur score anyways?
orz orz orz
38 / 80
i sold so hard on part a and b
ww
hmm
Halloa friend
hi gbawirel wang
hm
g=ohihi
hi*
no i think he got 34
but we dont talk about my comc
*i got into cmo from a different comp when i actually learned how to write shi
which comp
stilll big numbers fr
yea
hmmmm
yea i got 47
how u good at writing proofs but not straight solving it
huh
cuz
i like writing
lowk
*math
prove that if p is prime, p is prime
o thats a real thing?
Though it's probably advisable to be very sure to include "theorem" among your search terms.
i did include "theorem"
ohh me
Basically it's the theorem saying that every continuous tangent-vector field on a sphere must have at least one point where it's zero.
no even when u dont search theorem it still shows the theorem
chill bro i js finished elementary a year ago
why would you not search it with theorem
curious ykyk
you can't comb a hairy ball without creating a cowlick
there i dumbed it down for u
...
actually i should look at the proof
especially when going to the images section of google search
huh
wait it still js shows pictures of the theorem
Or: Assuming that wind speed and direction cannot differ abruptly between nearby places, there's always at least one place on earth where there's no wind.
yay?
wait why would u say this

I took his point to be that he doesn't know what a "tangent-vector field on a sphere" is, which is fair.
isnt that spinntnt thing
i learned abt it from 3b1b
also do not search up the plural form
hi
✌️
Hiya friend
ello
Hallo. Hru friend?
hello friend
Hallo friend
😍
Frrrr
i found the area of the two semi circle white parts and then subtracted from the whole thing
i did ts before
I’m pretty sure this is a version of an old mc problem
Something to do fan shape or whatev
if i have absolutely no idea how to approach, i might coordbash 
Too lazy to solve
ye alot of problems are like this
Subtract then figure out overlap area
cuz whole thing is like 50 and then subtract the area of the middle black thing (r^2x.577) from the two semi crickes
anyone doin the fryer galois hypatia contests this wednesday?
aw hell naw
yea
im facked
rip
yea me too
cooked 😭
u should make me proud
yes it is D
aww
which one
galois....wbu
This just depends on finding the intersection of the two semis right? It can be calculated using sectors and triangles
same galois
I'm in my hotel after cmimc just don't wanna do it
cmimc?
Carnegie Mellon math comp basicaly
orz
do u know what daily integral is
Nah I actually dont
there was a chicago team at cmimc
i couldnt pull up cuz of usaco open tho
i'm indoctrinating people rn 
Oh snap really what name
it's fun
idk
Oh tuff
Okay
is there canada at cmimc
betttt
integration is scary
any1 know of an international calculus comp available to undergrads
Intercollegiate Math Tournament maybe
integration easy fym
depending which integral you do ofc
not complaining or anything, thanks for the answer but maybe preferable in a place that's more local(asia) or like is online to minimize costs
although thanks for the answer
imma consider that if I'm bored
Most marks come from your organization of solution
howwas it
are u gonna make camp
also are u gonna make usaaio camp
i was watching the beaver edge lectures and saw u
o
Oh shi when’s the Euclid
Ok
your welcome 🙄
Its tkmmorow
gng..
integrate y=0
woah
easier than a lot of people think at least
thats what i meant
its not that scary
transfinite induction is more scary
flexing at its finest
ook i communicated it wrong 🦧🦧🦧
some integrals are not as scary as others
js look at the stuff roy posts
there are scarier things than integration
like transfinite induction
hmm
hey guys could any1 find the square root of 4489?
huh
67
did waht?
o
lol
fire pfp bro
ty
yw
also you have a fire 𝛈𝝰𝒎𝒆
hmmm
i love regular show
For me it's tomorrow
hmm
Mango
yummy
GIVE IT TO ME
🥭
yummy
I guess bro 😭
zelix plz
hallo im zelix
zelix replacement for now
locked in for midterm
good boy

jk
your the goat my friend
(sends virtual dap to heal bros feelings)
Halloa friend!!!!!!!!!
hi
hi @fringe prism
hi birdy
is that u in ur pfp
hru ?
top ten nigeshs
good wbu?
hi
hi zelix
hi friend
hiii
good. ty for asking. Also mitte
massachusetts institution of technology?
How nigesh felt after saying that
smth
😭
Tomorrow
I decided not to do that one, I'm in gr 11 but I requested to js do the Euclid instead. I didn't enjoy the category in grade 10 :/
gl
although euclid is way more difficult its good your still trying it
are you writing any?
good luck bro
appreciate it
tbh, I don't rly think it's that difficult....the first 7 q's can be pretty much solvable without requiring gr-11/12 knowledge
r u in canada or america
theres functions no?
it's pretty light
I mean yeah, but like they're pretty much on the easier side
like knowing Precalc is enough for Euclid
I agree, imma grind out and try to get perfect on 1-7 and partials on the rest. That should (please) guarantee me like a 70
get honour roll
yess bro, in all the past papers I js get stuck at the end fr
ik, same 😭
there really isn't a way to "study" especially for that section
have u got hnr roll before
yeah there is
do a ton of past contests and focus on the difficukt parts
yeah, cimc & cayley
yeah that's the only strategy, for studying I mean like notes to review and stuff, in this case best bet is to sharpen the intuition, else the questions are like totally random
I got the news when i started grade 11 😭
not rlly intuition
if you really focus you can find clever tricks and simple solutions
will this be for he upcoming yrs too?
that IS intuition
idk maybe it depends on ur school
Not school
They dont even display names on their website no more
yeah yeah
I think any normal person who practices enough can achieve that
Its all about practice
Intuition can only carry one so far
Waterloo will tell your school whether/not u got the honour roll and they'll send the certificate to them
theres a certificate for honour roll?
i thought there was only certificate for distinction (top 25%)
And the participation one
And outstanding achievement for gauss
wait I got this one 👆
is there a diff btw that and honour roll
YEAH
honour roll is the names on their website
distinction is practically worthless
Well its decent ig
I see
but then they got rid of that too
I'm not super cracked I got the top 25% ones 🙂
:(
Thats good
Aim for school champion
and if they bring back hnr roll, aim for that for next years euclid
do amc 12 also
I got the two
I did cimc, cayley and the other one
then I got top 25 in 2/3 and school champ in all 3 I think or 2/3
nah I go to a random ass school
anyways u shud sleep early
so ur brain recovers a bit of its fried braincells
Gl and most important hf
you too bro
what age is amc8, 10 and 12 for, i currently study outside of the us so i do the australian mathematics competition
Hello everyone!
I am studying combinatorics, and everything was going fine until I had to solve problems involving sums with binomial coefficients. I don’t have many problems with the combinatorial part itself, but rather with manipulating the sums to get the desired result.
Could anyone suggest any resources that I can use to improve my skills in working with summations?
Thanks in advance!#
it's giving the slander on this before mods deleted it (though some remnants remain)

<@&268886789983436800>
LMAO
To everyone doing euclid contest today best of luck and intellect to you
that problem is so sillyable
btw you can turn off pings when you reply if you click here
I might be fried
nooo euclid was soooo hard 😭😭😭
its actually disgusting
hmm
na
jk its better than alg and combo
lol
am I wrong?
Combi > Geo (imo).
Combi problems are more fun in their wording.
NT > Combi > Geo > Alg (for me)
hmmmm
By fun-worded questions, I mean Questions like these:
33 rooks are placed on a standard chess board. Prove you can choose 5 of them, which are not attacking each other.
NT is the GOAT, because of:
Let $A>0$ and $B=(3+2\sqrt{2})A.$ Show that in the finite sequence $a_k = \left\lfloor \frac{k}{\sqrt{2}}\right\rfloor$ ($k \in (A,B) \cap \mathbb{Z}$) the numbers of even, respectively odd terms differ by at most 2.
LemmaLover
ooh
yh combinatorics
Correct
me when a city boi tells me symmedian and i dont understand shi
ok
who else wrote the Euclid today?
how did it go
u did euclid??
And u have onetmmrw too?
meh, it was pretty difficult
I'm pretty sure I completed 1-5, ½ of 6? ⅔ of 9? didn't touch 10 can't remember 7 and 8
very grim
still have next year tho
another scam 
yea
did u
it was rly harder this yr especially the last four
im gr nine and my math is mid
o
yup
I know right 😭
it's okay, you'll surely do well
yea...but last year's wasn't that harder compared to this one
gng my province had a strike so spring was delayed and i have to euclid a week late
what? isn't that a security risk?
yea
hi
wsp
hi
and get into jmo
bruh i was so locked in this year
hmmm
are there any math exercises and that stuff
for wha
idk im bored
just anything
remember
imo 2024
same
WTFF

Wordle spoilers lmao
hmmm
wordle is easy
:p
unc
fahhhh
No five letter word is allowed
This is so stupid
fryyer is tommorow but few ppl do it compared to pascal
😭
yea
all my classmates did pascal basically
it's much harder no?
for me personally I hate proofs, counting, etc
hmmm
fryerr is same as euuclid formatting
more time per question compared to euclid
wayy easier
Unc
🔪
the joke has expired gng
is the ih?
I can’t type
greatt display name bruh
Just add extraa letter stupid
oh that's cool
yea
hmm
hey that not nice
Is the introo to probabilityy book tooo basiccc
then buy intermediate
It’s a questionn
u dont need extraa letters on everything 😭
(◡ ω ◡) ikr
Extraaa precautionsss
maybee for like amc 10 levell stufff
Stfu u snowflake
ts like a protest display name
Sooo i js goo too intermidiateeee
???
indeed
yea...
u should do introo before intermediate
review introo
wait i have intermediate open rn 😭
o wow
Okayyy
Guys wheree do i get ts bookss for free my websitee ain’t workingg
ask patrick
u can't
I use annass archive but it don’t work
hm
what??

itses notses
wait why does it only filter out certain words
words
todays wordle is pizza
Ay ay ay I still need help
You ain’t running
how are you able to type pizzaa
i fell asleep
the expected answer is just:
f(x) = c ln x
or
f(x) = c ln|x|
hm ok
are 5 letter wordss stilll banned
I think so but you change it by choosing the specific role
hmm
i didntt know theree was an esteemed participant role
dats cool
wheree?
It's an April fools prank, will likely go tomorrow
hehe ordinary citizen

Hello. I was wondering, couldn’t I just solve this for h = 0? Or would that kinda be cheating? (Ignore the coffee stain and crumpled paper 💔)
how
i alr told u buh
uh huh
That would be a neat corner case to consider -- but I wouldn't count on getting many points if that's the only kind of solution you present in an answer.
gabriela can tell u
wordle hints
sureeee
brown poop role
Makes sense. I already solved it in the way they were probably expecting, it’s just I suddenly thought of that corner case and thought it to be quite clever lol. True, though, probably wouldn’t get full points for just that haha
Even better, set h=w=0 and the length can then be arbitrary.
hmm
@thin pumice how did u do
why are u doing everything late
hmmm
GABRIELLL HOW DID U DO?
hmmmm
i did everything but last one @silver forge
oh WUT???
yea
i did all
another security risk
wdy get for last?
ima ask some kids in bc if they did it yet
whatdd u get for q fourss
I finished 3/4 stepss for last
ye
wendelin go dms
