look honestly ive never seen anything quite like this
i think i know the identities youre using
so sounds about right but im not sure ill be of much help
alright good because i do find this interesting
isnt there that formula
This looks most similar to the first identity in 4
Subtract it from both sides
actually if you add it to both sides
then sin^2(A) would always have to be 1
which is obviously false
sin^2B+sin^2C-sin^2A = 2sinBsinCcosA
Uhh I don’t get it?
Okay sure
suppose $\sin^2 C + \sin^2 B = \sin^2 A + 2 \sin B \sin C \cos A$ then $\sin^2 A + \sin^2 C + \sin^2 B = 2 * \sin^2 A + 2 \sin B \sin C \cos A$
Gijs
Gijs
Gijs
which by identity 4a implies 2sin^2(A) = 2 which is obviously false
There thats
wait i cant read
Umm np
What about we convert that cosA tho
Pretty hard maybe
$\sin^2 A + \sin^2 C + \sin^2 B = 2 * \sin^2 A - 2 \sin B \sin C \cos (B+C)$
$\sin^2 A + \sin^2 C + \sin^2 B = 2 * \sin^2 A - 2 \sin B \sin C (\cos B \cos C - \sin B \sin C)$
hii
help
$\sin^2 A + \sin^2 C + \sin^2 B
= 2 * \sin^2 A - 2 \sin B \sin C \cos B \cos C + \sin^2 B \sin^2 C$

Does this make sense
yeah makes sense
,w sin^2(A) + sin^2(B) = sin^2(A) + 2sin(B)sin(C)cos(A) where A+B+C=pi

nuu
,w evaluate sin^2(A) + sin^2(B) = sin^2(A) + 2sin(B)sin(C)cos(A) where A+B+C=pi
$\sin^2 A + \sin^2 C + \sin^2 B = 2 \cdot \sin^2 A + 2 \sin B \sin C \cos A$

Here we do sin^2 A = 1-cos^2A
Uhh this is actual question
I typed wrong
$\sin^2 C + \sin^2 B = \sin^2 A + 2 \sin B \sin C \cos A$
$\sin^2 A + \sin^2 C + \sin^2 B = 2 (1-\cos^2A) + 2 \sin B \sin C \cos A$
It helps?
,w solve sin^2(C) + sin^2(B) = sin^2(A) + 2sin(B)sin(C)cos(A) where A+B+C=pi

its a fun challenge though
Wait a min
yes and then perhaps use these
Thats true
Now i need to write it in some neat manner
well that was pretty cool

good luck
Thanks for being till the end 
of course
Thats good exercise
oh alright yeah that makes sense
And this was one of problems my sir gave as high level trig questions ig
isnt it deep into the night for you
It sounds weird to say high level lol
1 am lol
oh lol
well its certainly not straightforward
Well anyways i need to get sleeping haha
Oh nice
Same here
sounds like youre gonna do well on the JEE
Ohh
gn

You should also sleep then 
Anyways imma close now

I got this triangle, it's known that AD = BD, AE= CE, BF=CF
and we need to prove that ADFE and DECF are a parallelogram and that AC=4GH, I proved the first 2 but I am stuck at the last one
F is between B and C, I forgot to mark it

I am lost on where to put the x and y intercepts
Am I plotting the x and y intercepts on the original Cartesian plane or the new axis after the vertical shift up 1 and horizontal shift right 2?
And this is also confusing because I always thought hyperbolas never touched the origin? (0,0)
First off not a hyperbola
…
It is a hyperbola just rotated 90 degrees.. we had this conversation before. It belongs to the conic sections: parabolas, ellipse, circle, and hyperbola
I didnt have that conversation is it actually?
Yes it is
Anyways it has been shifted so it can touch whatever
As long as you did your algebra correct you should be good

hey
what are you solving for?
3-4i is just a number
that's like saying solve 19
3-4i is just 3-4i
Its a number
nothing more
what if

o
oh no another of these
unfortunately... yes.
eh u can use
those are problems of multiple variables, you need to write an equation to represent each line
then you perform substitution, cancellation, addition, subtraction, multiplication of equations to cancel out variables until you get one
i wll try to do one of these
oh i tried, but i ended up with -9 and i dont think its right
mhm i did that trying to find the missing segments of the line so i can solve for the entire thing to get JL in #1
@limpid talon Has your question been resolved?
oh hey i new i did something wrong
oh dw
i set up my equations wrong
im pretty sure i did that one correctly
make sure you verify all your veribles hold true to the original equations
there is some way you can go wrong. i forget what the taboo is though
you should have all the variables figured out by the end. assuming you wrote correct equations and it makes sense and all variavles are valid, you should be confident in your answer
ahhh okay
im outside rn so like ima get back to u once i understand the question / finish it when i get back
thank you smn

Hey, I've been struggling with a problem for a very long time, I'd appreciate some help.
Twice the measure of an angle is ten less than half the measure of its complement. Find each angle measure.
you can try setting up an equation
Yeah I tried but none of the answers I got made any sense
Been at this for like an hour and a half so like tried every single equation in this world's existence
Do you understand the vocabulary?
Well, according to what I'm seeing the two angles equal 90 degrees and 2x = y/2-10 but I'm not sure how to answer get the angle measures
Looks good
So how can you express y in terms of x, knowing that they are complementary?
x+y = 90 and would I do system of equations to solve the rest?
Or substitution
yh I didn't try this so let me see what I get, thanks a ton
Np
I get x = 14 and y = 76, when I do 2(14)=76/2-10 they don't equal each other, am I doing something incorrect
I believe I am

ik how to use definition of derivative to solve functions, however i've never done so with fractions like this.
not sure where to begin
This is what I have so far
@clear trench Has your question been resolved?
Quotient rule?
u∆v - v∆u
—————
v²
Lmao I'm not a helper but I'm studying derivatives too and that's what I do when I try to find derivatives with fractions.
You could also just convert it into:((6+x)½)^-1
prof says we cant use quotient rule since we havent touched it
only def of derivative
😦
Have you tried this? You can convert a square root from
√n → (n)^½
And also 1/n → (n)^-1
After that you can use power rule. And once you get the derivative you can convert it back.

an equivalent question is, for which values of k is 2021 divisible by k
ah so its 2 oops
see i got that like nk = 2021 and for some reason i only considered 43 and 47, and forgot to include 47 and 43
thanks
don't forget k=1 and k=2021

Which of the following is true? (there is only one): ∅ = {∅}, |∅| = 0,
|P(∅)| = 0, ∅ ∈ { }.
the second one is true, but i'm not sure what your explanation means
the empty set has no elements, thus |∅| is zero
ty
can you help me understand the last one?
I mean the 2nd to last
sure, do you know what P(∅) means?
p is a function where o is the set size
P means power set, doesn't it?
ok, so what's the power set of ∅?
well that's the size of the power set of ∅
what is the power set itself? what does it contain?
it contains 1?
no...
if A is a set
then P(A) is the set of all subsets of A
does that sound familiar?
yes
ok, so what are the subsets of ∅
nothing
almost true
it has exactly one subset
namely itself
(a set is always a subset of itself)
so the power set of ∅ is the set containing ∅
i.e. P(∅) = {∅}
and since the power set has one element, the size of the power set is 1
i.e. |P(∅)| = 1
sure

Hi ! I tried doing some exercices that i did in class but i failed to solve this one.
Say x belongs to R*+ such as: x + > 1/x = 5
Calculate x^2+1/x^2
How can i solve this?
(x + 1/x)^2 = x^2 + 1/x^2 + 2
this is classic competition problem
Can you explain to me why did we add x^2+1/x^2 + 2 to the other side?
And what happened to 5?
What about +2?
Adding 2
(x + 1/x)^2 = x^2 + 2 * x * 1/x + 1/x^2 = x^2 + 2 + 1/x^2
So you already did that
Did what

unsure how to solve this
try combining it into one fraction and then l'hopital probs
a method w/o l'hopital
fine, combine it into one fraction and then use taylor series
$\frac{1}{t\sqrt{1+t}} - \frac{1}{t}\ = \frac{1}{t\sqrt{1+t}} - \frac{\sqrt{1+t}}{t\sqrt{1+t}}\ = \frac{1-\sqrt{1+t}}{t\sqrt{1+t}}$

hi guys i’m not completely sure if this type of question belongs here but i’d figure i’d ask anyways,
the answer says it’s x^(1/2) but i simply just have no idea how they got it
which one lmao
oh i forgot 87 haha
well it's the same thing as the ones above
find the limit as dx goes to 0 of: f(x + dx) - f(x)/dx
so i plugged it in and got this
so what's f(x+dx) here
Delta x should be INside the square root
Wdym?
It should be 2 * square root (x+delta) not 2 * square root(x) + delta, if that’s what u mean
Yeah
And then it’s algebra time! (Hint, use difference of squares)
that’s (a+b)(a-b) right?
Yes!!!!!!!!!!!!
i feel like i did something wrong haha
Nah that’s very much the right way to do it. 👍
should i try factoring stuff out now?
U have to multiply it out
this is where i get the most confused
When u multiply it out, notice that in the numerator, the x’s cancel each other out leaving just a delta x
And just so happens that there is still a delta x in the down below denominator
Here’s the surprise: the cancel!!!!! Whaaaaaaaaaaaaaattttt!??????!???????!
oooh i see
nooo don’t worry i’m glad ur enthusiastic abt helping me lol
so i should have this now?
Yup!
You can finally let delta x go to zero without worrying about any weird things
So…….close…..to the…..the answer…..I’ll assume u got it
WELLLL
kinda
like i’m seeing it but also not
i feel like this should be clicking
i can combine them right since it’s x+0 which is the same as just X?
Yup!
Either way works fine cuz they’re both the same
Wait a minute, we must have done something a tiny bit different
Lemme recheck our stuff
There’s supposed to be a 2 in the numerator at the top of the fraction, because 2*deltax/deltax is 2
And then the top 2 and bottom 2 would’ve cancelled out and we’ll get the books answer
But we basically got the same answer, basically, so we got the core concepts down in the bag
Wait…..
Oh yeah, u right u right
ok so let’s see here
Oh it THAT is the right way to calculate it, I was off
Bro, I tell you, u got this in the bag
The 4 delta is correct
so i can cancel out a delta now?
Yup!
The 4 stays, it’s just the delta x at the top and bottom that go away
OH RIFHT
oh my gosh
so this is x^-(1/2) ?
wait
radical x over x
oh my gosh it is!!!
thank you so so much
Your very welcome. I’m happy you got it : )
oh @sudden birch i’m sorry
can i just get a confirmation that this is in fact
the same thing
because our teacher doesn’t want us leaving square roots in the denominator
Yup a Hundo percent correct
ok thanks again

Hey can someone help me with this
This is what I have to do
And I found the 10 factors of -14/3 (including positive variables) and none of them worked
Is it not supposed to be -14/3?
try small values of x to see if they make h(x) = 0
for x = -2 we get
$ 3(16) -17(-8) - 31(4)+23(-2)-14 = 48 + 136 - 124$ -46 - 14 = 0$
so x =-2 is a 0
so x + 2 is a factor use long division to simplify the quartic
oh yeah and 7 is the other one
doing long division will yield (3x^3-23x^2+15x-7)
i did it even further now
you'll find x = 7 is a factor of this too
so now I have 3x^2 -2x+1
long divide by x-7 you'll get
3x^2-2x+1
which has no real solutions as the discriminate is < 0 i.e. 4 - 4(3) = -8 < 0
so x = -2 and x = 7 are our solutions
there's no 3rd zero?
nope
yup
but see how we have sqrt(-8)
that is a complex number
so there are no real solutions to the quadratic (should have been a little more specific sorry)
can't i boil it down to 1+isqroot2/3
sqrt function produce a real number when the input is >=0 i.e
if your class wants complex solutions sure
they're not necessarily working with only real numbers
well it gives me the option to put an i
all zeroes implies they want the complex ones too
I assumed you where working with reals sorry
its fine
yes by the fundamental theorem of algebra you will need 4 solutions
yup!
no probs, sorry for the mix up

I need help calculating e for RSA Key Generation? I'm a bit confused on some of the tutorials/instructions I see. I have a p of 11 and q of 17. So that means I have an n = 187 and T = 160. Where I'm stuck is on calculating e, I am to do
gcd(e, T) = 1 but my instructor said that the number has to be a prime of your n = 187. However the only primes for 187 are my p = 11 and q = 17. Is this allowed and what do I do if not?

I thought i knew how union and intersection works in terms of set theory and intervals but I don't understand this one
(-∞, 6] ∪ [2, ∞) ∩ (-3,11)
answer sheet tells me the answer is (−3, 2] ∪ [6, 11)
What are you getting if not that?
(-3, 6) ∪ [2, 11)
Actually there may be a typo in the question
Since (-inf, 6] U [2, inf) = (-inf, inf)
are you sure it wasnt
(-∞, 2] ∪ [6, ∞) ∩ (-3,11)
That's my thought too
i got the left intervals from x <= 6 or x >= 2
what's the original question
i described it here.
#help-22 message
I'll post a pic of what's currently in my notebook too
so you're saying (-∞, 6] ∪ [2, ∞) ∩ (-3,11)
is it ((-∞, 6] ∪ [2, ∞)) ∩ (-3,11)
or is it (-∞, 6] ∪ ([2, ∞) ∩ (-3,11))
i think it matters which one it is
good question
you're not doing case work properly
ah
for the |4-x| >= 2
case 1: 4-x >=0
4 - x > = 2
...
case 2: 4-x < 0
-(4 - x) > = 2
...
wait do i need to do cases for |4-x| < 7 too?
(I'll probably find out if i do bc then i need to do even more work to get an answer)

Hey, could some one tell me if i did b right? it it right to just add zeros to make the matixes the right size?
unless you have something that says you can do that for this purpose (i can't read that language) you generally can't add matrices of differing sizes.
Just adding rows/columns of 0's isn't typically allowed.
Just says that if i cant do the following equation i have to tell why, but i you told me the rule. So thanks😁

couldnt find anything to that so im asking here, what exactly is he doing
I imagine it's the forward finite difference operator
how does it work
it must have been defined somewhere?
Need help

Hello!
Can I get sum help
Idk why this went up to two then just went side ways like that
The interval is -infinity to +infinity yet it turned sideways instead of carrying up the curve
what interval? the domain or range?
Domain yes
First one
Domain is IR
I can't for the love of me find out why we went sideways after reaching 2
why couldn't it? The domain is just the possible x-values. it doesn't imply anything about the range.
but why
this is what the range means
doesn’t necessarily mean it has to go up or down
Oh
I think you want the range
Probs didn't study ranges ig
the values y can take
f(x) = 1 has a domain of all reals.
it's range is only one value, 1.
maybe find stationary points
I study in French so I'm not good with English versions of math words so I'm gonna have to translate that one sec
But for that I need to draw it don't I?
I don't know how to draw a curve for a fonction with a division of two polynomials
oh you just differentiate
Hmm?!
My brain lol
Subtract what from what
I'm very sorry the English words in math are new to me so I have to Google them to understand
I can speak English just fine but have never studied math in english
🫂
oh it’s differentiation
have you learnt calculus
like dy/dx
Oh
f’(x)
Do we need that!?!?
it’ll be easier
Yeah we just learnt like basics of functions
We have a very different system than calculus and algebra
We all of them in like math
One subject
It's weird but derivation no not yet
ohh you’re learning functions
Yup
maybe you can do long division
How would that help?
😔
I give up
I just don't understand how we got a question with derivations when didn't study it

Ok so ur talking about lim x--> inf right?
I literally went and studied limits for this lmfao
hmm
im also not sure tbh
are you allowed to sketch?
right now I’m only able to think of finding dy/dx
maybe call for <@&286206848099549185>

hi i was wondering if you could help me see if their is anything wrong with my assignment .Is this allowed?
its usually bad practice to ask someone to look over your entire assignment on the off chance you have mistakes
it makes it easier for people to help you if you can highlight places where you are concerned there are mistakes, and why you think you may have made a mistake
or what you are confused about

On average, an adult female cat gives birth to 10 kittens per year. For every 3 male kittens there are 2 female kittens. How many female kittens will this cat give birth to in 13 years of her life?
What have you tried
I just know that it has to do 3m = 2f
I think we need to do proportion?
Or equations
First, how many kittens are born over 13 years?
But that’s the total amount of kittens born?
Ok nvm I got it
3x + 2x = 130
So it’s x = 26
26 x 2
52

Hint: $cA = (cI_n)A$
Zybikron
yes we did
oh yes that was det
mhm
is it the same
its the same idea
just follow this hint
vision
HellO
if we multiply everything by c
it would be like
2..2..2
diagonally
so its
2 * 2 * 2 * ...
somehow your c became a 2
so
but sure
amazing
thanks young one
oh theres more
btw yesterday was fun
👀
ikr
had such a hard time with the algebra
he spent more time
future deserved better
formulating the result of the proof
than doing it
just realised we also did this
yeah we did
also u got the green role
thief
yes u are thief
ni hao
nihao
idk
chi zao can le ma
i stripped em out
may they rest in piece

ni ma ma mei you mao
..
wat
im sorry what
MODS
why u do dis
D:
gonna get banned at this rate
we did do it
no pls
no ban
b&
hey
$det(A^{-1})$
HellO
no
hurt me feelings

i think
the bots are smart enough
wait
no but
ur telling me they give the role via the number of msgs
the bot knows who opened the channel
watafak
Wow look at you cool people with your green names >:( /s
ye
o
idk if they count that
oh its gamer dio
noob

yeah surely gamer dio should have green too
like a bot
:D
