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

- sin (2 x) - 2 cos (x)

Solution steps

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

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

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

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

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

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