is this like a maths memes thread?
Welcome to calculus
unless...you know the derivations for those theorems
literally me to myself all throughout last year

0 doesn't exist
what's the function
ok i figured it out
f(x) = xβ΄ - 7xΒ² + 6x
take its derivative
f'(x) = 4xΒ³ - 14x + 6
then solve for f'(x) = 0
that means 4xΒ³ - 14x + 6 = 0
(dear god please don't try to solve by hand)
you'll get 3 solutions which are these marked points
the x values that satisfy f'(x) = 0 will create those "turning points"
intense desmos trials
and solving equations based on your x intercepts
alright so you have a function
do you know what a derivative is
well shit
@muted crow what exactly do you mean by "why are turning points there"
you mean "why is it there and not anywhere else"
or "why does it exist"
i'll be completely honest
the derivative method is probably the easiest way to find out the exact location of the turning point
do they ask you to calculate what those points are
that's a sigh of relief
this doesn't look like what you plotted on desmos
ah
looks good
also another thing
if you have more than one brain cell unlike me you wouldn't go through all of this
because you know
you have the intercepts right there
all you have to do is (x + 3)(x)(x - 1)(x - 2) and voila
for x = 0
plug x = 0 and you get y intercepts
then you'd pass the line through (0, 6)
because that's what the y intercept means
the function passes through the y axis at that particular point
that's not possible lol
you can't have two different values for a given x

bro got a head start lol
oof
hey look its the thread i made for cheating on tests
the thread I made
lmao
linear algebra is my vietnam
It took me an hour to figure out that question
oh hell nah π
oh yeah its this thread
that i used for cheating on tests
i still dont understand math
my math is ran by hopes and prayers
NOOOOOOOOOOOOOOOOOOOOOO
Bro this math thing
im getting questioons with more letters than numbers
some without a number at all
is this the start of my downfall
It's euler's formula.
who is euler and why did they create whatever nonsense this is
Mathematician, to torture multiple generations of students after him.
rude guy tbh
but luckily im not gonna touch that ever
i think
i shouldnt have to atleast
I had the honor and pleasure of being invited to deliver an address for the mathematics graduation ceremony at Stanford. In it, I chose to talk about one of the lesser-addressed and awkward-to-talk-about motivations for getting into math.
i finally understand marh
What grade is that
its sequence and series, it starts pretty basic and can torment you in calculus
Start of 11th
some fuckking number just appears out of nowhere
Ans is above
okay look
first
You take x/5
And put it in line with 1/10
Basically you rewrote x/5/10 as x/5 multiplied by 10
h
grrrrrr
i have left that questionb ehind
what it supposed to be
see?
i need help
tf is that
what
but another question
ohhh
correct
i am supposed to convert decimal to whatever its called
smh rocket
please help i have done this test for 10 mins
11/10
i have done 3 questions
ok
ok danke

Which fraction must be subtracted from 31/13 for the result to be 2?
@glacial light
help
Which fraction must be subtracted from 10/9 for the result to be 1?
Which fraction must be subtracted from 55/18 for the result to be 3?
nope
ok
5/13
to be subtracted
ok so you take the unknown value as x
yes
so 31/13 - x =2
then solve
you get 31/13 - 2 =x
then x =5/13
31/13 - 5/13 = 26/13
=2
alright thx bby
13 x 2= 26
yes
can you help me with the 10/9 but not tell me the answer and jjust help me think
yes
hhhhhhhhh why does this have to be so hard
i dnt get it
i have 6 mins left of this test fuck
fuck fuck
yes
so 10-9/9
i dont get where the other 9 comes from
x=1/9
LCM
you multiply the denominator so that you can solve
10/9 - 1
that one is 1/1
same thing
1 x9/1x9
10/9 - 9/9
= 10-9/9
which q
nah the test results
last one was 97/100
oh
and i lost 2 because danne moment
bad resultaten
what did you go through?
this chat is astonishingly important
yes
Ping when needed
thx bby
@mint slate
You draw a rectangle where one side is 4x cm long. The length of the other side is 2cm.
What is the perimeter of a rectangle?
What is the area of ββa rectangle?
What is the half Perimeter of the rectangle?
what this
its just 4x
that usually means 4 times x
one side is 4x the other side is 2
Im alive
4x and other side is 2
hmmm
Perimeter is 2(length+breadth right)
so that's 2(4x+2)
8x + 4
8x
Si
4x + 2
Half perimeter is 4x+2
danke
area is 4x times 2 = 8x
8x+4
8x
danke danke
4x+2
thank ball too
danke ball

aw man i fucked up on a question
i forgot to add X to the end
but i know it so its all fine
bruh
F
so...what's the question again?
class over
ok
oh
Danne can do his own maths
i cant
i asked the fucking teacher for help but the idiot just went "but do this" and didnt explain what i needed help with
When some jobless dum dums on a discord sever are more helpful than an actual math teacher
epic moment
yooooo danne maths thread
I HAVE MY GRADE 11TH FINAL MATH EXAM TOMORROW
BUT I CANT STUDY
CUZ I AM IN LOVE
FUCK
HELP??
Danne
You want to no math
Math

Basic maths
That's all I can help with sorry
yes thats y i will cheat

you do you
lmfao stop-

I can't believe this is an actual thread
should be 144 = 64 - 8x
i am the biggest idiot when math
Yes so if you move it to the other side it becomes -64
8x should be -8x
if 64 becomes -64 it should be 144 - -64 no?
No
The two 40 cancel out
So it just remains 144
Then you move the 64
And it becomes -64
ah ye im being dumb
So 80
8x should be -8x
no clue
So x=-10
but what did the eqaution fuck up
The 8x
ye
i wont answer that
Alright fair
Everything
Nah its not that bad is it
A) what did robin fuck up
he miscalculated in division 3
he dropped a minus sign in step 2
he did not divide in step 1
he miscalculated the subtraction in step 1
he divided by the wrong number in step 2
he dropped a minus sign in step 1
pls help
He dropped a minus sign in step 1
Iβm pretty certain
Step 1 is the second line right?
yes
So that
He forgot the minus of the 8
Yessir
thanks babe
π«
now i atelast look smart

thx again
not now
Ok cool
math
Yes
math can die
I like it 
As long as I understand it
probably
idk
i just try to do the math the teacher throws at me
which doesnt make any fuckign sense at all
so X^2
yeah probably
So why are you still doing these 1st degree equation
If you already did the 2nd degree ones
(Thatβs how we call them in italy)
we have exam in like 7 weeks or something idk
Fine
and we have to repeat it
here random question
its all just fucking gibberish
Quadratic is degree 2
Yes true
I cant combine english and meths sorry
Too slow
@obsidian ginkgo what I got
I was taking it as 118
How do you solve it
y2+24y+118
Same way, just arranged differently
Ohk
Agreed
Like so
Donβt mind the scribbles
Thatβs just me being dumb
And getting the lcm wrong
Lol
What did you need LCM for
There
Just a different way to solve it compared to opc
Still correct tho I think
i think we are both correct
Ye
Ohk
Thatβs the fun of maths imo
So many different way to reach the same result
h
very nice to hear
ladies
or lads
i might need you in a sec
shorten as far as possible
@mint slate
Si
i am supposed to put the "normal numbers" in its own
Yes
and then 24a^2 in its own and so on right
but the divided by 4 is scare
help
like the bottom one becomes 15+3y+18y^2
now should i divide that by 3
right
Wait whatβs the point of the exercise
Wait actually
h
Oh right
Couldn't we divide the whole thing by 4
Becomes 1- 6aΒ² - 6a + 2a technically no?
can we?
@glacial light
polynomials are my weakest
- i just woke up from a nap
Yea you can
oh?
this?
but shouldnt i add the 6a+2a into 8a
not too sure
If you divide them all by 4 it should be correct
Si
Yea of course
4x+(5x-7) shorten this
The second one isnβt right
The two 10 cancel out
So itβs just 5-b2
wait do they
how do they cancel eachother out
oh right its a -
Yep
What are this weird blue tables on the right tho
Like why do you need to write them there
this is right correct?
Yes
its so you can do like - if you cant use a keyboard like an idiot
Ooooh lmao
Yes danne gg
what q
right
This isn't the final answer right
When the Bullhinken bakery restarts after renovation, they have 73 customers in the first week. After that, they get 10 additional customers every week. In the second week, they have 83 customers.
a) How many customers does the bakery have on the 26th week after the start?
b) How many customers have visited the bakery in total after the 26th week after the start?
c) How many customers have visited the bakery in total after the 40th week after the start?
nah
U have to find b, a ,y
U might be right
323?
@fluid pelican
I donβt get it whatβs the difference between the first 2
me neither
It's a + (n-1) d
but there is difference
a) is 10 right
Wait
Isnβt it both 73 +26*10
No me dum
It's how many visited in the 26th week and the b is the sum of them
No
wai
Well then the first one is simply 10
They get additional 10 every week
It isn't 10
the first week they have 73
It's 323
2nd is 333?
then they get 10 more each week
b is 333?
That means that in the 26th they got another 10
Ye so whatβs b
oh god AP vibes
Same thing
B is 13 x (73+323)
arithmetic progression
im just waiting to dump that chapter
Not 323?
73 customers + 26x10
Ok right Iβm dumb
25 or 6
So isnβt the second one 26*10
oh
25
f u
First one is 323
It says after tho
323 then
@fluid pelican this one its right correct?
i slapped it into google translatee it might not be perefect
After the 26th week tho@atomic willow
Second one will be 5148
Like does β26th week after the startβ include the first week
They are asking 26th week only I think
40th week then
Dude how
The start means the start day then
5k?
n/2 (a+an)
idk i got wrong on one of these and 5k doesnt seem unreasonable compared to the same question i had while studying for this
Yeah
This the formula for sum
what is this 
the first one is simple an = a + d(n-1)
shorten as far as possible
a) 323
b) 5148
c) ?
Ah
a doesn't seem right
but im probably stupid
Like if they get 10 more every week for 26 weeks why isnβt it 73+10*25
AP nothing seems right
oh i got the wrong values
it is that
second one is also that
Yes
n/2 (2a+(n-1)d)
Where did the 5k come out from
solve this
why are we stuck here on a stupid problem
what's the actual proble
danne gave me one
y'all discussing another one
i wanted to double check the one i gave you
it's this
will be 40/2 (146+390) π
40 weeks?
danke
the only correct option i see here is c
which qsn?
hold on lemme wash my hands
im eating snacks here π
how?
am i reading it wrong?
atually nvm
First one is -4a not 8
Second one is + b
yea
Yes
final answer is 9260
it's for 40 days why would you take (a+an)
cause i had not calculated anything before
ohk too lazy to calculate
don't mind me i barged in
oh
quick this
i got 4 mins until i have ran out of time
what i think
pls someone
2 mins
a is 4
d is 3
n is.. in this case 3?
welp anyways
4+d(n-1)
i mean
huh
4+3(n-1)
subsituite n as the number given there
u get your answer
well lets see if we can get it in the desired format..
4+3n-3
1+3n
there we go
3*n+1
is that what you need?
ye
also i have no clue what a ant pricker is
epic
ooh i see
ah fuck times up
where?
too late anyway time ran ouit
where's the qsn
learn it rather than asking us
bruh this was a test?
i have tried to
-_-
its impossible
it's actually quite simple mate
what grade is this for?
yeah
gud boi
bro....
rationalisation moment
my teacher once cut my marks for that.... finally the hod had to say it's fine give him marks
your answer is technically incorrect ig
if you are in cbse, your teacher was right
and your hod dumb
im in cbse
the hod said that coz those marks count for internals
and like they don't want to mess up reputation
oh so basically cheating
Gives marks for it even though it isn't correct
Not cheating

Good job
You guys are great at meth
Here's a hard one
Where is pie
There is no pir symbol
π₯§ 69 squared
pi squared?
meth.
Howβs meth goin dame
Good good
lovely
thx
Took like 10 mins
you're the man
Someone please explain me trigonometry
what do you need help with?
Everything
that's rather vague lmao
Do you think I understood anything about trigonometry?
||maybe, idk||
Ya still need help, also what in trigo do you not understand
like the basic concept itself or just a few formulea
omg π₯Ί
My past comment already says everything
I know nothing
so what do you want to know
in trigo
like you want to know th meaning , or just formulea
the direct meaning is it helps make a relation between sides and angles of a triangle
https://www.esaral.com/properties-and-solution-of-triangle-notes-for-class-12-iit-jee/ well technically this is for some indian entrance exam and stuff but it does have a few of the more important formulea especially with regards to a bit of advanced trig then there are also inverse trignometric functions which if you want i send that also
this should cover most of the basic formulea and stuff

63
How do so many people think itβs 25
63
Danne -5*-5 isnβt 63
nvm
it would be -25 if it was -(5)^2
yes
its 10 π
Even i
2+2=4x4=16
How do I calculus
use wolfram alpha
remember the days when our math had actual numbers in it
and not just letters
how what
yes π
Remember the elementary school
wow
can you help me with quaternions
quaternions ez wait till you start doing addition
i made a mistake by going to wikipedia
p β¦ qβp for q = 1 + i + j + k/2 on the unit 3-sphere. Note this one-sided (namely, left) multiplication yields a 60Β° rotation of quaternions


heck na

u thought uwu came from anime or some shit
think again
its quaternions .
uwu is a sin
true
lmaoo

How did 6/2 x (1+2) turn into 6/2 + (1+2)

2+2=4 2x2=4
What is this hell
well you can assume x is 1 if (x/5)/10 x 5 (because 10x5 is 50 to match) and 5x10 is 50, so 3x10 is 30. x/5 would be 1x5 so it'd fufill 5/5 and would therefore be 1/10, which you would just carry over as an extra 1, if im correct.

kek
w h a t
Im too lazy to process this
But yea sounds about right

Since when can you have a fraction whithin a fraction
since fractions were a thing
Its just rewriting
1/10 x X/5 could just be rewritten as X/5/10
its simplification, wheather that makes things simple or not......debatable
Imma just ignore what you said. Cos my brain hurts. And wait for my teacher to teach me that later in the year
same
wait a minute
Today calculus melted my brain
how is 1+1 not 11
1+1 is 1
because if you add 1 pile of gravel with 1 pile of gravel
you get 1 bigger pile of gravel
had me wondering for a while till i realised the error 
you're right
spoiler it for the others
