derivative of

f (x) = cos^{3} (x)

- 3 cos^{2} (x) sin (x)

Solution steps

\frac{d}{d x} (cos^{3} (x))

Apply the chain rule:

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

= 3 (cos (x))^{2} \frac{d}{d x} (cos (x))

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

= 3 (cos (x))^{2} (- sin (x))

Simplify

= - 3 cos^{2} (x) sin (x)

ln (\frac{1}{x})

\int e^{3 x + 2} d x

ln^{2} (x^{2})

\int_{0}^{14} 2 π x (14 x - x^{2}) d x

\frac{d}{d x} (e^{x^{2} + 3})
