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

- 2 sin (2 x)

Solution steps

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

Take the constant out:

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

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

Apply the chain rule:

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

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

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

= - 2 \cdot 2 sin (x) cos (x)

Simplify

- 2 \cdot 2 sin (x) cos (x) : - 2 sin (2 x)

= - 2 sin (2 x)
