Question

Differentiate f(x)=cos^2(x)sin(x)
PLEASE SHOW ALL WORK!

Answer 1

Product rule!!

Answer 2

chain rule!

Answer 3

ok chain rule and product rule.
you've got to use what you need to get what you want

Answer 4

use \((fg)'=f'g+g'f\) with
\(f(x)=\cos^2(x), f'(x)=2\cos(x)\sin(x), g(x) = \sin(x), g'(x)=\cos(x)\)

Answer 5

whoa a mistake
\[f(x)=\cos^2(x), f'(x)=-2\cos(x)\sin(x)\]

Answer 6

So what would the answer be?

Answer 7

i don't know, i didn't do it
