\frac{d}{d x} (cos^{2} (8 x))

- 16 cos (8 x) sin (8 x)

Solution steps

\frac{d}{d x} (cos^{2} (8 x))

Apply the chain rule:

2 cos (8 x) \frac{d}{d x} (cos (8 x))

= 2 cos (8 x) \frac{d}{d x} (cos (8 x))

\frac{d}{d x} (cos (8 x)) = - sin (8 x) \cdot 8

= 2 cos (8 x) (- sin (8 x) \cdot 8)

Simplify

= - 16 cos (8 x) sin (8 x)

(5 x + 3)^{\frac{1}{5}}

f (x) = - \frac{3}{x ^{2}}

\int 14 cos (x) d x

x^{^{'}} + 4 x = 0

\int e^{- 22 x} d x
