derivative of

f (x) = sin^{3} (3 x)

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

Solution steps

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

Apply the chain rule:

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

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

\frac{d}{d x} (sin (3 x)) = cos (3 x) \cdot 3

= 3 (sin (3 x))^{2} cos (3 x) \cdot 3

Simplify

= 9 sin^{2} (3 x) cos (3 x)
