this is the problem right
i tink
cant you cancel the bottom out
angone know the answer?
i got rhat
yeah multiply it out
how the hell
how
is that thr actual answer?
u expand the ()
why tho
bc then u can simplify with long ivisosn
then i made two dif integrals
simplify the integral
yeah
yea and plug in and you’re there
see
😣
will i get flamed if i say math < chem
im taking chem next yr i think
is it ap
bruh its so fun
i don't like remembering all the rules for solubility and whatnot 
so rubbish LOL
tf is ap math
they’re all the same in their triviality
not ap HL
ap
high level maths
AP precalc should not exist
my school is weird
is advanced placement
it’s easy asf you’ll be fine
guys did you solve the integral
yea
it’s 2/35
no
did i do the wrong problem
yes
you did, in fact, do the wrong problem
ts is wrong
oops !
ap ap
it’s really simple
ik it's binom theorem
LOL
DAILY CALCCC
it was stupid ash
also where tf is this daily integral
it’s on the website
yo i’ve managed to reach the medium
let’s flipping go
the hard one tho i have no idea how to do ts
i've only been able to solve the hard like 2-3 times a week
😔
ok
i js started doing daily int
niccc
$\int_0^1(x+1)(x^2-x+1)\ \dd x=\frac54$ was my first prob
nadat12
yayy
the easy and beginner ones are really really easy
mayb
wha
dyk
i split into intervals
but dunno how to proceed
oh wait
yo i got a question
i could prob headsolve sin^2cos^2 x
how do you learn the stuff to do the hard integrals
?
oh
yeah
nvm
i read it weong
1/4 sin^2 2x
usub
[0, pi/4] 1/8 sin^2 u
wait i forgor about factor 💀
and then int by parts?
holy shit
aw fck i dont wanna differentiate the top gng
taylor series expansion
tf????
idk the taylor series icl
taylor buhbuhbuh
icltspmo
wait
wtf do they mean "taylor series"
could i lhopital bash?
you don’t need the series
i’m looking at the app
sol*
yo guys
are there any channels that teach stuff for amc and shi
wouldnt this be the closest..
what
do you mean servers
js like swap the summation and the ingegral to get $$\sum_{n=1}^{\infty} \frac{1}{3^n} \int_{0}^{1} \lfloor(2^n*x) \rfloor$$
wait how dyk you can do that
vivdax
fubini's
and i also have no clue how to integrate floor functions
also like double counting
break it up
into the intervals
so integral of floor(2x) from 0 to 1
would be integral of floor(2x) from 0 to 1/2
and integral of floor(2x) from 1/2 to 1
which is integral of 0 from 0 to 1/2 and integral of 1 from 1/2 to 1
i said not ap, but hl
whats hl
THE GOAT
yo i’ve seen this guys vids
like
while teyna find ones to watch
do they acc help
probably
probably
yeah but for sum rheres lile theorems and stuff i don’t know
so i can’t do some problems at all
wait havr you watched any of his stuff
try learning them
on theory
?
and then like try to do problems on it
wait
also you can js get like books in general to work through
that’s what i’m tryna accomplish with the yt vids
high level french version of ap basically
guys which one do we feel is better
o nice, im taking ap french next yr
mastering amc 10/12 course or amc 10/12 fundamentals course
bro i hate french
i’m gonna take ap french eventually
?
probably like doing a buncha past rpboelsm
but i hate french
pourquoi?
my teacher
i know how to solve it now
RIPPP
so
that wasnt an option icl
its embedded in the 1st one
sigh ig i’ll js do past problems
like it has a bunch of stupid rules
i started doing ts
or smth
i started from like
yea
as in
basically
the language might be like nice
the 2000 mavs
oha ight
amc*
well english is lwk dumb too
yes
bruh its like easier to learn than like mandarin
no mandarin is eadsy
how dare u
le passe simple ☠️
js memorize the characters
im not dissin gmadnarin
good
do like 1854 amc 10 B
choose a random year from 2000 to present
stop.
english: i dont have rules. i mean, i have rules. but i break all of them more often than i folow them
LOLLLLLL
imparfait my baby
yo what is this
do 1776 amc 10a
french: EVERYTHING NEEDS RULES
passé composé as well
i js know futur simple
bruh passe compose = free
rules for everything 
and then spanish is like
and futur proche right?
most cooked tense
then they went along and had a baby i believe
plus que parfait
that’s easier than simple
yup
EW
o do twa
I HATE PLUS QUE LATFAIT
my teacher says it’s not really a tense
i know french
onb
MOI AUSSI
,w random number from 2002 to 2025
a or b
A
in the middle
A
eh
,w a or b
i’ll do both
bruh lol
i have truth tables
truth tables are lowkey boring
all i need is smth to watxh now
nah cs made me hate them
my teacher bever taught them bever mentioned them and they pull up on a unit test
yeah but i never knew what they were
my dad told me once in like 5th gr
i relied on my old ass memory on that test
LOL

buh

i remember i got the easy int down to [0, pi] 1/8 sin^2 u du
i forgor int of sin^2
it's int by parts right
what's the integral of sin^2
wait im dumb
use reduction formulas
ye
1/2 -1/2 cos2x right iirc
or sum
so [0, pi] 1/16 - 1/16 cos 2u du
[0, 2pi] 1/32 - 1/32 cos v dv
pi/16 by symmetry buhbuhbuh

hey

hi
hard integral is like pretty easy after ||summation swap||
i js did binary expansion
and guess
binary expansion??
ye
and then
like the digits appear half the time
so i got ||3/4||
by geometric series
Hello
This is like that MIT integral but it isn't squared lolllll
lol
Hi
Hi
Hello zelix=pro
Hallo frannah
You good?
yea wbu
Same
Hi
hi people
that’s nice
Hi child
Ik
hi
Hi
Hi friend
Well i was in #latex-testing
What that
patoi is better
hi
i cant solve this math problem
a^2+b^2+c^2 = 42 then a,b,c equalc=?
any a,b,c ?
are they in real? integers? natural number?
well there's infinitely many distinct solus but 8 integer solu
idk how you'd solve this other than plug and chug 
no way there is only 1 integer solution
integer
hm
yk
42 = 2 mod 4
any square number either 1 mod 4 or 0 mod 4
so (a,b,c) there are 1 even number and 2 odd numbers
that would lower possible cases you have to try
hellorrr zelix
hallo friend
i am in7th
so it would be in integer
there ain't many numbers to try
you know 1 of them is even
and a,b,c =<6
42-6^2=6 obv not
42-4^2=26
42-2^2=38
i would just try it till it works
no integers work, so plug and chug would be pretty hard
8 triplets work
i THINK
plug and chug is my best friend in comps
o
try each answer until one of them works
when i have no choices left, i must 
i have no brain, and i must think
||26-1^2=25=5^2
26-3^2=17 ||
||38-1^2=37
38-3^2=29
38-5^2=13||
that's really fast
8 calculations
a chinese kid can do all of them in 30s /jk
we need super computer
bruh so real
oh sry its not squars its cube

cube make it even easier
yeah no no way that one could've been solved
what if a is super huge, b is super huge, and c is super negative
cube of a negative is still negative
hmm
well
That would be a problem
yea @inland totem
@inland totem got solution?
this was solved in 2019
a quick google search will tell u
yea, but we need integer solutions
or 42
it's 1,5 and 4
omgg @inland totem
oih it is
,calc 16+1+25
hmm what
Result:
42
mb 🥹
One set of integer solutions for (a^{3}+b^{3}+c^{3}=42) is: (a=-80,538,738,812,075,974)(b=80,435,758,145,817,515)(c=12,602,123,297,335,631)
MEOW
mhm
yeah it's a famous problem
requierd 1.3mil hours of computing time
so def not doable
not yet, wait for me /jk
i'll give u like 50 years
i dont want
Nah, I only need 2
just kidding, I don't even like number theory
Imma just try and forget about it tomorrow
hi
yo
it gets easier once u learn more
but it's mid, in my opinion
:||
hallo
I’m at school
i have school tmrw
me too

isn't that unsafe?
what if there's like a dangerous situation and u have to call ur parents?
Exactly
🥹
I guess i can use my imagination to figure out what they were watching
in school.?
yes 😔
🥹 they couldn’t have waited a couple more hours to get their freak on
I just started eating breakfast 😭
HAHA
L
I know a lot of Texas had em locked (I used to live there)
what time zone r u in 😭
no it's actually 6pm rn
i wasn't hungry the whole day
LOLLLL
bruh I js got out of math
math

at least it was math
my late classes are latin and ap physics
nerdy ahh stuff
latin 😭
the dead language?
🥹 yes
I hate math
im the only good one in the class so i have like ten tons of pressure on me for this like national exam
why 😭
Idk, js not that interesting
understandable
real chem is better (but more boring)
idk to talk
u have a math tag too 😭
fr 😭
valid
idk what tag to put
LOL frr
put the tag of a socializing server??
it’s not that deep
It’s fun to talk abt math
FR
math
heyo
yohe
for those who need a state mock before mathcounts
stay tuned
GIFT CARD
OOHHHHHHHHH
can i take it even if im not doing math counts 🥹
Hallo
I wish
aw i can’t
like how the kids in my school watch family guy and... family guy irl?
family guy isn't bad
Fr
family guy irl
that's bad
LOL
theyre only grade 8s btw. some g7s and 6s...u say that aint bad?
let's not talk abt that
gonna get u smited by mods
LOL SO rubbish
go fofr it
for it
i might increase the prizes
hooraahh
aime = goat
thanks
hey i increased prizes to 30, 20, 10 hop in
hey yiz

RIPPP
just doing alot of chess puzzle timing myself for 1 mintue
i love chess
some i can solve under 1min
other i cant
that because my puzzle rating is high so it more complicated
it’s 11 pm and i’ve spent the past 45 minutes editing amc8 solutions honestly so much fun
b r u h
lol
LOL
LOL
i think i’ve done almost every single one i’ve added my very unneeded input
are you pereena?
why do so many tests use buffalo shuffalo
i see pereena everywhere lmao
its on so many problems
your comments are so unfiltered😭
at least use capitalization
LOLLL
no literally 😭😭
mb
i think i was very helpful in fact
SUEPR HELFPUL!
so much easier
FR LOL
cuz the explanations always use these like patterns that no one knows
penn equations
bruh js write down all the numbers on paper and js keep doing it till ur at hte 10th number
SO LONG THI
just do we go down 9 terms and the common difference is 7 so 100-9*7
it works for me tho 😭😭 probably not for others so i understand why the formula would wanna be use
nighty night
good night
no formila just common sense
k bye
exactly
bye acorn
bruh real
done with eveyrthing
besides studying for math
(meeting with calc bc teacher tmrw = cooked)
me too i’ve even moved on to doing amc10 problems
i’ve edited all the amc8 one i even did some from 2013
do 12
i don’t think i’d get past problem 8
12 and 10 are pretty similar
its like bad after problem 15
they are similar but 10 and 8 are more similar
No 12 has different topics
theyre like not even close
idk i only did AMC 8 once
O
hoenstly AMC 10 was more easier for me so i just took that multiple times
real lol
did you do AMC in school?
yea, u cant take anywhere else(for us at least(
goodnight guys ima sleep now
yeah, everyone was talking tho cause the teacher they gave me sucked
ttyl
aw rip good night
ohhh # LOLL
i can’t sleep 🥹🥹
does SAT count as competition math
no
ok
hell no.
what about ACT?
the sat and act is just the default high school curriculum, so no it is not competitive on any level
i mean people in the Olympiads are usually under 20
so i thought I'd ask
Yes people who do Olympiad math in the USA will probably take the sat or act like most high schoolers in the USA
ok
just
if u can do well on olympiad math, you can definitely do well on the sat
the converse is not true
noo rip
LOLL
hiii
absolutely not
anyone have any good tips for hamilton olympaid?
any good free resources or learning materials ( apart from obv past papers )
drfrostmaths is goated for ukmt prep, they have walkthroughs for the hamilton
thank you i will check him out
hi
wyd
if maybe spend around 6 hours a week from now until the day of the comp on march 20th I believe, should I be fine? I have my gcses as well just after the competition
very good mock grades in maths and further maths but very little experience of proof writing ^^
Hi
i’d try for at least an hour ish a day if u can
i will try to fit it in
proofs are the biggest jump so practice writing your arguments out clearly
I should practice writing proofs before jumping into any questions right
I tried fidgeting with some of the questions and found out I can do some of it but I have no idea how to write arguments and notations for the proofs to get the actual mark
im at school,
LMAO
that sucks

Hi friend
zelix we just had a dr*g intervention on another server
Wha
help what 😭😭
LOL ok
show me too pls 🥰

anyone doing the ccc tomorow?
the waterloo one (its CS tho)
and theres a math one later this month
juniour / sr?
yo can someone good at math competitions help me out rq, my friends are doing a comp and im tryna find out how to prep for it
im not a beast but i was able to get top 25% in 2/3 i competed in last year
what i can say is for the week/weeks leading to the competiton immerse yourself in that problem-solving kinda mindest
so i'd solve a year's papers, then on my commute to school id watch someone solve the same year, that way im learning my corrections even though im not at my desk or sth
lowkey might ahve ot do that
i dmed you tho cuz i wanna fill u in a bit
if thats okay
alright
which comp?
i could help
DID SOMEONE SAY MATH COMP
Hi
probably IMO
what about cs comp 
or mop
what abt usnco 
hmmm

omg im failing ts
Gg.
shits tommorow as well
wait this isn't that difficult
it's like that counting squares, if i'm understanding it right
brhu real
u cant brute force it tho
time complexity is gonna be O(n2 . k2)
u need some form of queue if im not mistaken but im not bothered to learn dsa
big o notation?
i think i'm understanding that wrong

yessir
hmmm
im doing pascal later this month, but my school might fake our age but according to my school ccc is for g9+
i don't wanna think abt that rn
i did cayley last yr, was top 25%
its the multiple choice one (same w pascal)
noiceee genius
im not cracked i js try my best ✌️
im doing the gr11 version of pascal later this month then imma do the euclid
hmm
what comps r u talking abt
canadian ones
hosted by university of waterloo
oh i live in murica sadly 🦅 🇺🇸 🛢️
sadly?
i only like amc here
i did amc8 and got a silver once
before i migrated here
amc 8 only has dhr, hr, and stuff like that
so u got second in the whole country?
i was in nigeria so the way its administered was different
and i wasnt 2nd in the country, it was like a % threshhold of people
ah ok, so like in the us
several ppl in my school got "silver"
hmmm
i got 2
ye 2yrs ago
i first took it in 4th grade and sold 😭
RIP
i did it pretty young too
wait what are the scors for gold/silver/bronze
bruh i started in 8th
what did u get??
what grade rn
10
ur an unc
i think like a 17
how do you even take math olympiad
bruh YALL are unc
mine isn’t out idk why
i'm a youngling
i dont know the grade equivalent but i was prob 10yrs-ish when i did it
(16 now)
fr
same lol
you’re unc zelix
yes u do
😵😵
prove it
im too lazy to write my test
supposed to get it 3 months go
LOL real
id rather do like chem and violin
predicted scores??
o shoot, i got got
for my drive test?
uhh sure
i know how to play the toddler piano 🥺
are u proud of me
real
i need an 80% to get it so i'll aim for around that
because free will
what that
yes unc
excuse me 🥴🤮😬🤧😬😬😬
tuff
ikr
😐
HELP IM JK
r u tho
