or half angle sub

[sturdy knoll]

yeah i don’t understand where those come from

i mifht have to watch sum vids on ts

i’ve never learned the hyperbolic trig functions

[inland totem]

hmmm

good time to learn them

[sturdy knoll]

wait people are saying it’s just slightly diff

shi nvm

that’s js the identities

[little wraith]

hey guys

[sturdy knoll]

what u all been upto?

[little wraith]

i’m driving to skiing

[inland totem]

skiing?

[sturdy knoll]

fuck ahh csp

[little wraith]

yes.

my parents r making me go

[merry scroll]

what's that?

[little wraith]

skiing?

[sturdy knoll]

comp sci principles

[inland totem]

skiing is fun - i've been a few times

[merry scroll]

okok

[little wraith]

yea i rlly like it but i’ve gone like 10 times in the past week and im tried

tired

i have break so i wanna rest

[sturdy knoll]

what the hell

bro i’ve never gone oncr in my life✌️

[little wraith]

really!

[merry scroll]

yeahh me too

altho i saw ppl skiiing

[static torrent]

hi

[little wraith]

i’m here 😔

[fringe prism]

!!!me soon

[fringe prism]

hi friend

[little wraith]

hello i’m skiing soon

[inland totem]

👍

[fringe prism]

hi have fun friend

[fringe prism]

Hi Patrick

[sturdy knoll]

what events are you doing

for scienxe olympiad

[inland totem]

last year i went to national science bowl

[sturdy knoll]

i’ve never done scienxe bowl

imma join it soon tho

[sharp oak]

Ooh I joined that this year too!

[barren anvil]

is that myster da 400 elo I see

[wraith tartan]

"2100"

[fringe prism]

me2 friend

[sturdy knoll]

guys

could someone help me on the amc 10 b 2025 problem uh

21

i don’t get jow to do ts

i’m thinking of a way but idk if it’s right

[inland totem]

hmmm

i'll take a look at it

wait idk exactly how to do this either 😭

[jaunty ginkgo]

Can you like post the question here

So people don't have to find

[sturdy knoll]

uh sure

[inland totem]

i mean i'd advise u to draw a 3 by 3 grid, place a random color in the center, and just assume wlog what the possibilities for the other colors are

[sturdy knoll]

that’s what i’m trying

what is wlog

[inland totem]

without loss of generality

used to narrow down math questions without affecting the validity of the solu

[sturdy knoll]

i reach a point where i have 3 squares remaining

[inland totem]

so continue with cases, i guess?

like set a square to be a color and iterate on that

then choose another color that works, etc

but i don't really know

[sturdy knoll]

idk i did smth like that

sum srupid method

somehow got the answer

so ig it works

[inland totem]

yep

i got 12

aops isn't loading so idk if it's right

[sturdy knoll]

it is

ts is how i did it

idk if it makes any sense

[inland totem]

that's basically how i did it

[sturdy knoll]

i dtill lwk don’t get how yellow can’t be in the second box on the middle left

[barren anvil]

wait lowk doesnt it have to be a mult of 6?

[sturdy knoll]

howd you get that

cuz if that’s true it brings andwer choices down to 2 obly

[barren anvil]

yeah

thats why I aske

I'm probably wrong tho

[inland totem]

cuz yellow would force the other 2 squares to not have any viable colors, so 0 cases for yellow

[barren anvil]

because then they would make them all multiples of 6

[sturdy knoll]

you right

i thoufht of this while solving

then forgot afterwards

[barren anvil]

amc10b was kinda hard

[sturdy knoll]

i did better on it than the a

[barren anvil]

same

70.5 -> 99

[sturdy knoll]

i lwk bombed both tho

[sturdy knoll]

holy crap

howd you do on aime

[barren anvil]

3

I couldve solved 5 without sillies

[sturdy knoll]

ah i see

some kid in my school is cracked ash

[barren anvil]

I sillied #2 bruhh thought it was 5-digit

[sturdy knoll]

he got like 7 he knows fs

[barren anvil]

wha get

[sturdy knoll]

he forgot the rest of his answers so he might’ve done better

[sturdy knoll]

yo chill

we don’t speak about it

[barren anvil]

xdxd

cant be that bad

[sturdy knoll]

it is yo

i got like a 60..

chill on me

[barren anvil]

on which one

[sturdy knoll]

b

[barren anvil]

oh

[sturdy knoll]

chill on me

[barren anvil]

#6 was really hard

on b

[inland totem]

it's fine

[barren anvil]

guys was aime ii harder or aime i

[sturdy knoll]

yo what’s the divisibility tesy for 11

[barren anvil]

alternating digits difference

[inland totem]

is divisible by 11

[sturdy knoll]

explain

[inland totem]

pretty sure this can be proved with modulo

but too lazy

[sturdy knoll]

what do you mean by alternating digits difference

[barren anvil]

like lets say its 1573, then 1+7 = 8 and 5 + 3 = 8, so 8-8 = 0 which is cong. 0 (mod 11)

[inland totem]

like in 121, 1+1-2=0. the digits in odd places minus digits in even places

[sturdy knoll]

oh

[barren anvil]

bro look at how short p13 was on aime ii

[jaunty ginkgo]

you should derive it yourself, it helps you find divisibility test for any number

If you able to do it for 11

[inland totem]

normally i just multiply and sum digits until the divisibility test makes sense

[jaunty ginkgo]

lmao

[soft vigil]

oh lets go

i got this one right

[barren anvil]

hmm

where have I seen this guy ebfore

oh OMMC

[barren anvil]

do you think aime ii wa sharder or aime i

[soft vigil]

idrk

i skimmed thru the aime I

different tests

different cutoffs

so

[barren anvil]

aime i was so sillyable

[sturdy knoll]

how would you go about doing 22

[barren anvil]

so, the MAXIMUM value of the sum has to be 63

[sturdy knoll]

huh

[barren anvil]

so do casework on how many digits are not 9, etc.

[sturdy knoll]

yo wait

how

[inland totem]

yep

[sturdy knoll]

oh

OHHH

[barren anvil]

it honestly is the easiest by far out of the last 5 this year

[inland totem]

wait could u use stars and bars for this?

nvm

[sturdy knoll]

whatd stars and bars

[barren anvil]

yes

then just eliminate the bad cases

[inland totem]

ehhh

too lazy

[sturdy knoll]

wait maximum sum is 63

but it says it’s 61 here

meaning that

at least one of the nunber isn’t 9?

[jaunty ginkgo]

eh? i have seen this question b4, like 6 months ago

[fringe prism]

what qyestion

o that one

[little wraith]

is this amc10?

[sturdy knoll]

yeah

wait so for this problem

[little wraith]

ah ok i thought i recognized the problem

[sturdy knoll]

more than 1 of the numbers canr be 9

[fringe prism]

can or cant

[sturdy knoll]

cant*

my fault

[jaunty ginkgo]

I remember doing this,
||sum odd place - sum even place = 11k||
||sum odd place + sum even place = 61||

you can get the bound for the first equation

[sturdy knoll]

wait yooo

[jaunty ginkgo]

k can't be that large

so k=0,1,2 maybe

[sturdy knoll]

chilll ion want the answer js like guide me through it

hints anf stuff

[jaunty ginkgo]

oops

sorry

[sturdy knoll]

thanks

[inland totem]

wait for stars and bars, u need to remove the constraint

oh i can just set another variable

[sturdy knoll]

what is stars anr bars

[inland totem]

search it up

too complex to explain

[fringe prism]

u can js use modular arithmetic and combinatonrirs

[sturdy knoll]

wair wouldn’t stars and bars work exactly for this problem

[snow thistle]

it counts the number of ways to order indistinguishable items into distinguishable boxes

[sturdy knoll]

wpuld it be 11k or

shouldn’t it just be 0

[jaunty ginkgo]

ehh idk get the bound yourself

[snow thistle]

this question is so troll

[fringe prism]

rela

real

[jaunty ginkgo]

highest sum odd place is 4*9

[inland totem]

hmmm is it ||3/14||

[snow thistle]

they should make it like

sum to 45

[jaunty ginkgo]

bla bla

[snow thistle]

and then you havet o use genfunc

[fringe prism]

what i got

[fringe prism]

@vagrant dragon u shud try this

[jaunty ginkgo]

oh wao

the problem sucks

9*7=63, lol

[sturdy knoll]

i’m so lost

[sturdy knoll]

what’s genfunc

[jaunty ginkgo]

this problem is ass

[sturdy knoll]

yo idk what i’m missing

[jaunty ginkgo]

9999999 what's the sum of digits

[little wraith]

fr

[jaunty ginkgo]

in this number

[sturdy knoll]

ik that’s 63

[inland totem]

a polynomial where the sum of coefficients is the ans

[jaunty ginkgo]

yeah

so to get 61

[snow thistle]

generating functions

[jaunty ginkgo]

you can....?

[snow thistle]

kinda yeah

[inland totem]

just count number of 7 digit whose digits sum to 61

[sturdy knoll]

like

[inland totem]

then count number of those who are divisible by 11

[sturdy knoll]

it can’t be all 9’s

it has to be like

[jaunty ginkgo]

make a digit 7 or make 2 digits 8

[sturdy knoll]

yeah

[jaunty ginkgo]

yeah this problem ass

[jaunty ginkgo]

Don't even have to go through this step

[sturdy knoll]

wqit then what

[jaunty ginkgo]

just count

using divisible rule

for 11

[sturdy knoll]

yeah i get like 3 diff cases

35-26 whoch doesnt fit the rule

34-27 which don’t fit

and 45-25 which also don’t fit

i feel like i messed up

[jaunty ginkgo]

9+9+9+9-(9+8+8)=11
9+9+9+9-(9+9+7)=11

[sturdy knoll]

oh shit

[jaunty ginkgo]

These are only cases there I think

eh, I'm a bit lazy to check

[sturdy knoll]

oh fuck

bro

there’s no way i messed up on basic addition

[jaunty ginkgo]

happens

[sturdy knoll]

now do i js gotta see all possible permutations for the nunber

[inland totem]

i believe 25 36 is the only case that works

so a1+a2+a3=25, and b1+b2+b3+b4=36 (b=9)

ci=9-ai

so c1+c2+c3=2

yields 6 cases

[sturdy knoll]

what the hell is c

[inland totem]

just a substitution

stars and bars is hard with an upper bound sub

[sturdy knoll]

sigh imma learn thid stars and bars sruff ion get ts

[barren anvil]

holy yap what did I Just come back to

[inland totem]

math

this is math discord after all

[sturdy knoll]

imma skip ts problem

come back afyer

[barren anvil]

if you wanna feel good try amc10a 21-22 this year

super easy problems for placement

[sturdy knoll]

bro whatbthe hell is this probability problem

[inland totem]

i don't like probability either 😔

[sturdy knoll]

bro why was problem 21 so easy and now ts is so weird

[barren anvil]

I dont like combo 🙁

[barren anvil]

I believe 22 and 25 are also not tha t bad

[sturdy knoll]

22 idk stars and bars

so idk how to do it

[barren anvil]

for amc10a

[sturdy knoll]

oh

wait

[jaunty ginkgo]

you don't have to know lmao

[sturdy knoll]

bro i was looking at problme 24 instead of 23

[barren anvil]

wait I can try to come up with a solution without stars and bars to show u

[sturdy knoll]

i did it your way

[polar rampart]

Hie

[sturdy knoll]

but i didn’t get the full solution

[jaunty ginkgo]

hm

[little wraith]

are we still on #22

[jaunty ginkgo]

yk there are 2 cases

9+9+9+9-(9+8+8)=11
9+9+9+9-(9+9+7)=11

[barren anvil]

ok the cases are all 9 but one 7, all 9 but two 8s right?
try all the cases, ther are only 28 in total so it shouldnt be that hard

[inland totem]

he's on 23 i think

[barren anvil]

you COULD count them like actually, but you can just count all 28 cases

its not that bad of a bash

23? of which test

[jaunty ginkgo]

just use simple combinatorics bruh

[long garden]

didnt you already q20 was deadass so dumb

[barren anvil]

21 and 22 were also dumb

dumber actually

[sturdy knoll]

20 was stupid

[sturdy knoll]

yeah

i got ts

i somehow mess up on the combinatorics part ofnit

[jaunty ginkgo]

9999997 has 7 permutations, 9999998 has 7C2 permutations

[barren anvil]

bro 21 was the 2nd easiest question of the test, 22 was THE easiest for amc10a

[jaunty ginkgo]

9999 has to be ood places

[little wraith]

i have a love hate relationship with combinatorics

[inland totem]

same

[jaunty ginkgo]

that makes 997 and 988 have to be in even place

997 has 3 permutations

[long garden]

no

[jaunty ginkgo]

988 has 3C2 permutations

[long garden]

they were much more solvable

q20 was js coordbash

also i drew 5 separate diagrams for that question and noen of them were right 💀

so i have a personal saltiness factor

[jaunty ginkgo]

I kinda like combinatorics, since I can actually do them mentally

w/o doing algebra stuffs

[sturdy knoll]

i got ts

[sturdy knoll]

yo what

[inland totem]

did u solve the 11 divisibility yet

[sturdy knoll]

almost yo you gotta believe✌️

[sturdy knoll]

yeah

that’s 3 as well

[jaunty ginkgo]

10^{2n+1} = -1 mod 11
10^{2n} = 1 mod 11

This's how you derive divisibility by 11

[inland totem]

i have an on-off relation with modular arithmetic

[jaunty ginkgo]

what does that even mean lmao

[sturdy knoll]

mines js off yo

[inland totem]

sometimes i hate it, sometimes it's ok

[jaunty ginkgo]

I always hate number theory

[sturdy knoll]

doni plug 3 in for n??

[barren anvil]

yes??

[barren anvil]

mines js off yo

[jaunty ginkgo]

no idea what you meant

[barren anvil]

but combo is arguably worse

[sturdy knoll]

so

[barren anvil]

and algebra is lowk underhated

[sturdy knoll]

i got that in the 997 case 3 permutations

and 988 is 3 as well

[long garden]

alg CANNOT be underrated

[sturdy knoll]

what now

[long garden]

its like

the most mained subject

😭

[barren anvil]

underHATED

[jaunty ginkgo]

Combi is really cool

[long garden]

oh

i cant read

llwk yeah

[jaunty ginkgo]

I hate algebra so much, I lowkey rely on wolfram alpha

[long garden]

well they're easier so

idm!

[barren anvil]

but thats kinda bad

because I spent 30 minutes on #4 and got it wrong

[long garden]

q21 was copied

[barren anvil]

so was q22

[long garden]

q22 was literally an alcumus question

[barren anvil]

I actually knew descartes lol

so it was the easiest for me

[inland totem]

it's cool, but sometimes makes me frustrated

[barren anvil]

someone at my school got 127.5 and didnt know descartes

[sturdy knoll]

bro i didn’t jnow decartes

i did it afterwards using herons i think

[long garden]

descartes was litearlly used in the year before too like..

[barren anvil]

combo gaslights you into getting the wrong solution even though you are 95% sure that you have the correct answer, it does that enough times that you are only 20% sure of the right answer 😡

[barren anvil]

EXACTLY

people should stop complaining

about descartes

[long garden]

i think i read up about it in like july 2024 or smth

[inland totem]

decartes is cool 👍

[inland totem]

yeah, ig

[long garden]

its fire

[jaunty ginkgo]

Yeah it is annoying

[long garden]

bc you get to avoid doing dumb shit

[long garden]

for some reason i just realized what you mean

[barren anvil]

........

.

.

[long garden]

i thought you meant the person got 127.5 for the problem and i was like

what..

[barren anvil]

no

[long garden]

LMFAO

[inland totem]

🤯

[barren anvil]

I got 70.5 and i knew descartes

dnag

[long garden]

is it ur first time aime qualing

[jaunty ginkgo]

skill issue

[inland totem]

bro descartes is lowkey so useful

[sturdy knoll]

fibally i got the problem

[inland totem]

what did u get

[sturdy knoll]

3/14

[inland totem]

did u use stars and bars

or casework

[sturdy knoll]

nah i used fionnas eay

casework

[inland totem]

mkay

[sturdy knoll]

i kept messing up my combinatorics

[jaunty ginkgo]

stars and bars makes it more complex ngl

[thorny tusk]

watre yall talkin bout

aime?

[jaunty ginkgo]

also, stars and bars is not that good, I mean it not versatile

[ivory ember]

hi

[jaunty ginkgo]

Compare to generating f

[barren anvil]

yes

[jaunty ginkgo]

[barren anvil]

its my first year doing amcs

[inland totem]

no?

only 28 numbers

and 6 that satisfy

[jaunty ginkgo]

you set ai and stuffs, I mean I can just count cases, 2 cases and it's only few of them, 3 or 4 so you can actually count it mentally

w/o doing math

[barren anvil]

ye its just 21 + 7

so you can just count

[inland totem]

but this is normally to generalize to more complex problems

and ye, i see ur point

[jaunty ginkgo]

use generating function

[inland totem]

this is amc 10

[jaunty ginkgo]

it's a joke lmao

[inland totem]

i don't think everyone knows what that is

[barren anvil]

amc10 sometimes has generating function tho

[inland totem]

yes, i've seen that

[barren anvil]

but honestly the best strategy to solve a combo problem is to ignore it and move on 🙂

I unfortunetely made the mistake of solving 11 wrong

on amc10b

otherwise i couldve gotten HR 🙁

thats why I dont do combo anymore

[jaunty ginkgo]

that's actually a good move, it's pretty hard to spot pattern in combi problem because it's designed to, if you trained enough you can have good intuition for geo/algebra but ehhh combi is a whole different story

[barren anvil]

fr

even alg better ;d

[fringe prism]

that's gone

[soft vigil]

what is Descartes…

[fringe prism]

a french philosopher

[soft vigil]

Oh yeah

why is that important to know

[fringe prism]

cuz theres a lot of mank in it

[little wraith]

hi zelix

[inland totem]

a circle theorem

[little wraith]

he created a theorem

[fringe prism]

the kissing circles one

[fringe prism]

hi funny dog

[inland totem]

cuz circles 🤤

Hai

[little wraith]

hai

[soft vigil]

yeah how is one supposed to know that

I don’t even know what that is

[inland totem]

it's not complex

easy to remember

[snow thistle]

there was no reason to know it

anyone who told you they knew it is a fucking liar

[inland totem]

better to know more formulas

[snow thistle]

it’s some bs

[inland totem]

jesus

no way it's that useless

[snow thistle]

genuinely it’s never popped up anywhere else

[inland totem]

wdym

u never know

[long garden]

2004 amc12a p19

2017 amc12a p16

[snow thistle]

just because you can solve it with that doesn’t mean anything 😭

like this year it was genuinely the BEST way to solve it

to use descartes

[long garden]

but you should lwk learn it tho

[snow thistle]

which is just fucking stupid

[snow thistle]

not really

[long garden]

more stupid thing is the fact that it was directly copiied 💀

and the most basic application

[inland totem]

bro no formula is completely useless

[long garden]

and i would argue it was the best way to solve those problems too

[inland totem]

it's always gonna pop up somewhere

[fringe prism]

real

[inland totem]

unless it's acronyms

i hate those

[fringe prism]

prob gonna pop up on 2026 jmo

[snow thistle]

are we serious

[fringe prism]

better safe than sorry

[snow thistle]

crazy ragebait

[fringe prism]

ay, u never know

https://tenor.com/view/i-guess-bro-i-guess-bro-bro-what-whatever-you-say-gif-16572066316579867256

[inland totem]

bro i've solved amc 10 questions with vector calc

u really can never know

[snow thistle]

doesn’t mean you should 😭

don’t overkill for no reason

[inland totem]

but if it's easy, then i should do it

[little wraith]

lowkey off topic but uh has anyone looked into the binomial theorem

[snow thistle]

and people learn all these useless theorems just to get like 6 on aime

[snow thistle]

it is 100% not the easiest way to solve an anc 10 problem

with vector calculus

[snow thistle]

like people think knowing niche olympiad geo theorem is cool when they can’t even qual olympiad 😭

[inland totem]

do u know how easy it is to use calc in the amc problems where u can spot it?

it's always the easiest antiderivative or derivative 😭

[snow thistle]

literally name one example of an amc problem that was easiest with calc

other than this year 10a p9

[inland totem]

bro

[fringe prism]

yes

its for like (a+b)^n when n>4(usually)

[little wraith]

yea i’m learning it now

[inland totem]

2018 AMC 10A Problems/Problem 21

uses curvature too

[snow thistle]

you can just use algebra 😭

ok in aime there are SOME cases where knowing calculus can help

sometimes people use calculus to evaluate sums for genfunc

[inland totem]

but calc is fun

[snow thistle]

i guess man

do whatever you want but i feel like sometimes people use calculus when they can just use algebra 😭

and it makes life harder

idk

depends on preference too

[inland totem]

ehhh

some cases

amc 10 rarely has those cases ig

[snow thistle]

ok but this year i cant believe they made 10a p9 like that

i barely know anyone who did it without calc

[fringe prism]

(me)

[snow thistle]

orz

[inland totem]

2025 amc 10a isn't that easily solved with calc

just find the num of solutions to a polynomial

but yeah, calc would help

[inland totem]

do u know calculus

[fringe prism]

i thougth evyerone did

[inland totem]

not really

[inland totem]

so u do know calculus

[fringe prism]

yee

i did an mit integration mock and got 0/20

[hazy jewel]

is anybody Taking BMMT?

[inland totem]

so why don't u go over to #calculus and see if u can solve today's problem

[fringe prism]

what da problem

[hazy jewel]

oh heck no

[fringe prism]

bru

[hazy jewel]

im in 8th grade

[fringe prism]

if i got like money then id prob do it

[hazy jewel]

what is ts

[inland totem]

it only looks hard

[hazy jewel]

im learning precalc

[hazy jewel]

what is this used for?

[inland totem]

[fringe prism]

ohhh lol

so rubbish lol

[soft vigil]

bro what

[fringe prism]

LOLL

[soft vigil]

name a problem

[inland totem]

long since forgot

but i'll try

[thorny tusk]

6+7=x. solve for y

[inland totem]

ts too advanced

[thorny tusk]

ikr

[fringe prism]

HI

[fringe prism]

i js finsihed proving a random trig identity

feels so good when done

[tiny eagle]

y=y

QED

[inland totem]

WHICH ONE

I MUST KNOW ALL THE TRIG IDENTITIES

[tiny eagle]

Imma guess he proved arctangent addition

[fringe prism]

problem F

super free but very fun to do

idk why

[pallid tundra]

#geometry-and-trigonometry

[fringe prism]

o shoot mb

[tiny eagle]

Multiply top and bottom by tan?

[thorny tusk]

lol

nah

y=z

😃

[fringe prism]

no multiply top and bttom by cotx+cosx

[daring sparrow]

guys am i orz

i got a 6 on amc10a

and a 7.5 on amc10b

[inland totem]

tuff

[daring sparrow]

(all from blank questions btw)

[inland totem]

or simplify the denominator

[fringe prism]

u get like 20 something for all plank

blank

no u get 37.5

[daring sparrow]

i answered some of them duh

[fringe prism]

oh lol

[fringe prism]

im like they dont have a common denominator so that would make it a bit messy and rubbish

[daring sparrow]

i'm literally the orziest orzlord out there

[inland totem]

eh, cosx/sinx-cosxsinx/sinx is easy to find

then flip the fraction , and it simplifies to the answer

[daring sparrow]

that's pretty smart actually

find x from 1/x

lolol

[fringe prism]

thats like pretty manky

[inland totem]

eeehhhhhhhh

[fringe prism]

im like it depends onthe person and their ways, (if theyre nlabbis or not)

[inland totem]

mhm

[daring sparrow]

did anyone qual aime

[soft vigil]

nah u get 42 on 12a

[daring sparrow]

damn 42

[fringe prism]

did they increase it?

[daring sparrow]

what are you taking

[soft vigil]

cause p25 was voided

[fringe prism]

bruh me ):

[soft vigil]

and if u just put in some practice i dont think aime qual is too hard

[daring sparrow]

we need a mopper to teach us the ways of the mop

[fringe prism]

im nevr mopping

0.00001%

[daring sparrow]

0.0001% for me

slightly better

guys try doing this integral

it's 1968 putnam p1

[little wraith]

do 6x7x41x420-/1722

[inland totem]

CONTOUR INTEGRATION

WAIT NVM

[little wraith]

i will try

[daring sparrow]

literally just partial fraction decomp

[inland totem]

wait i solved it

[daring sparrow]

nic

[inland totem]

js partial fractions

🤦‍♂️

[daring sparrow]

ts is too easy for a putnam p1

[inland totem]

oh cool solu

22/7-π

[daring sparrow]

yeah

it proves that 22/7 > pi

since the integrand is obviously positive

[inland totem]

there's something called division

dunno if you've heard abt it...

[daring sparrow]

but ts is more elegant 🥹🥹🥹

[fringe prism]

LOL the pfd

pov 1/1+x^3

[daring sparrow]

also apparently

$\int_0^1\frac{x^8(1-x)^8(25+816x^2)}{3164(1+x^2)}\ \dd x=\frac{355}{133}-\pi$

[gilded halo]

[little wraith]

i did not do this right

[fringe prism]

cooked^2

[tiny eagle]

Neither did I I’m genuinely brain farting

Where’s the pfd

[orchid linden]

? wait how do u partial fractions this

[tiny eagle]

Exactly what I’m saying

[little wraith]

this is hurting my brain

[daring sparrow]

rbo

just expand

not that hard

[tiny eagle]

Oh

Wait then it’s not pfd is it?

[orchid linden]

ye i thought about that but how do u integrate x^4/(1+x^2)

And similar terms

[daring sparrow]

no it is

[daring sparrow]

rbo

polynomial division

[orchid linden]

huuuuuuuhhhh

[daring sparrow]

polynomial division and pfd rbo

[orchid linden]

bruh

Dis not elegant whatchu talking about

[tiny eagle]

Oh I was being extremely narrow minddd

[daring sparrow]

yuh it is

[tiny eagle]

I thought it was only pfd

[daring sparrow]

ts so elegant

evals to 22/7 - pi

since integrand is always positive

22/7 > pi

[orchid linden]

Ok yeah the answer is cool I don’t want to polynomial division tho 🥀

[daring sparrow]

womp womp

[inland totem]

hmmm

[fringe prism]

Wassup

[plain yew]

i made another question today have a go: 🙂

[fringe prism]

let’s assume k=0 so d/dx k dx = pi ^2 +k so we know pi is sociable by pi therefore it’s not a square

[plain yew]

im so confused rn where are u pulling k and derrivatives from

or are u fw me i can't tell im sorry 😭

[fringe prism]

LOL I am XDDD

[plain yew]

I CAN NEVER READ SOCIAL CUES THRU TEXT

[fringe prism]

it’s so obviously off LOLL

[little wraith]

hehjekskaisuejmwwmkxidur

[plain yew]

bro idk man sometimes i see some random solutions that acc work

but ik enough that d/dx k dx = 0

[daring sparrow]

those who 67 💀☠️

anyways sum of tring numers

,texsp ||$\frac{(p^p+1)(p^p+2)(p^p+3)-p(p+1)(p+2)}6$||

[gilded halo]

nadat12

[daring sparrow]

claim: ts is never a square

proof: lowk idk

prob mod p and shi to see if quad residue

[plain yew]

thats kinda close to the answer ig?

i finally did this one

idk if it’s right

you should have 22/7 - pi

[long garden]

looks right

[daring sparrow]

its not 2/35 btw

[little wraith]

oops 😌

how tho

chat says it’s 2/35
