>mfw there are people on sci RIGHT NOW who don't know calculus

it's not knowing that's hard. it's doing the excersises so you can recall menial shit like cos'(x^2)= cos(x^2) * (2x)

or what the trig identities are. along with their inverses.

like am i supposed to know that cos(x)=sqrt(sin(x)-1 by heart?

>like am i supposed to know that cos(x)=sqrt(sin(x)-1 by heart?


Why is that so hard to remember? You can remember the quadratic formula, can't you? This is even simpler.

...

I'm in algabra 2 trig, and in college.
I never gave a fuck about math until it hit me that if i major in anything but a stem feild i might as well not bother with college, so now I'm trying to catch up hard.

You took the bait, friend.

mfw

i don't use the quadratic formula i just put my equation to zero and solve for x.

>bothering to know calculus when you can just numerical differentiation it all away

Come back when you learn how to program.

>cos'(x^2)= cos(x^2) * (2x)
It's actually cos'(x^2)= -sin(x^2) * (2x) brainlet

fuck off i only just recalled this.

0 = 44x^2 - 321x + 52034
Solve this without using the quadratic formula or using technology

You can solve literally any quadratic just by completing the square

sup

0 = 44x^2 - 321x + 52034
-52034= 44x^2 - 321x
[sqrt(-52034)]/44=x^2-321/44x
sqrt([sqrt(-52034)]/44)=x - -321/44 sqrt(x)
sqrt([sqrt(-52034)]/44)=x + 321/44 sqrt(x)

x=0 in this.

all you have to remember is the pythagorean theorem and the definition of a derivitive. everything else can be easily derived (^_^) from that.

what's the pythagorean theorem again?

>it's hard to remember simple rules for derivatives

Good job you triggered me.

It's not trig that's hard it's having to recall menial shit like the relationship of the hypotenuse of a right triangle to the length of its sides.

sin a / A = sin b / B = sin c / C

> cos(x)=sqrt(sin(x)-1 )
>implying cos(x) is never negative

w e w e w e w e w

>x=0
>0 = 44(0)^2 - 321(0) +52034
>0 = 0 - 0 + 52034
>0 = 52034

Bruh

cant tell if bait but that's the law of sines

...

I just use iteration lol
