\frac{d}{d x} (sin^{4} (2 x))

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

Solution steps

\frac{d}{d x} (sin^{4} (2 x))

Apply the chain rule:

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

= 4 (sin (2 x))^{3} \frac{d}{d x} (sin (2 x))

\frac{d}{d x} (sin (2 x)) = cos (2 x) \cdot 2

= 4 (sin (2 x))^{3} cos (2 x) \cdot 2

Simplify

= 8 sin^{3} (2 x) cos (2 x)
