derivative of

- sin^{3} (x)

- 3 sin^{2} (x) cos (x)

Solution steps

\frac{d}{d x} (- sin^{3} (x))

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= - \frac{d}{d x} (sin^{3} (x))

Apply the chain rule:

3 (sin (x))^{2} \frac{d}{d x} (sin (x))

= 3 (sin (x))^{2} \frac{d}{d x} (sin (x))

\frac{d}{d x} (sin (x)) = cos (x)

= - 3 (sin (x))^{2} cos (x)

Simplify

= - 3 sin^{2} (x) cos (x)
