Question

Find the derivative of y=sin^(-5)x - cos^(3)x

Answer 1

First derive the sin/cos, then multiply it with the derivative of what they contain. (Not sure how to explain it)

Answer 2

it's not divided though, it's subtracted?

Answer 3

Huh? No see let's use an example. The derivative of cos 8x will be the derivative of cos*derivative of 8x=-sin (8x)(8)=-8sin(8x)

Answer 4

first you pray.
Then you give thanks
then you hope
