derivative of

1 + cos^{2} (x)

- sin (2 x)

Solution steps

\frac{d}{d x} (1 + cos^{2} (x))

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (1) + \frac{d}{d x} (cos^{2} (x))

\frac{d}{d x} (1) = 0

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

= 0 - sin (2 x)

Simplify

= - sin (2 x)
