Question

Find the derivative of
h(x)=tan^3x

Answer 1

use the chain rule

Answer 2

\[\frac{d}{dx} (\tan(x))^3\]
You have a case where:
\[\frac{d}{dx}(f(g(x)) = f'(g(x))g'(x)\]
, the chain rule, applies. Using f(x) = x^3 and g(x) = tan(x) see if you can figure it out.

Answer 3

3tan^2x sec^2x

Answer 4
