derivative of

(1 + cos^{2} (x))^{6}

- 6 sin (2 x) (1 + cos^{2} (x))^{5}

Solution steps

\frac{d}{d x} ((1 + cos^{2} (x))^{6})

Apply the chain rule:

6 (1 + cos^{2} (x))^{5} \frac{d}{d x} (1 + cos^{2} (x))

= 6 (1 + cos^{2} (x))^{5} \frac{d}{d x} (1 + cos^{2} (x))

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

= 6 (1 + cos^{2} (x))^{5} (- sin (2 x))

Simplify

= - 6 sin (2 x) (1 + cos^{2} (x))^{5}
