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
