\frac{d}{d x} (cos (a x))

- sin (a x) a

Solution steps

\frac{d}{d x} (cos (a x))

Apply the chain rule:

- sin (a x) \frac{d}{d x} (a x)

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

\frac{d}{d x} (a x) = a

= - sin (a x) a

11 - x^{2}

\int_{0}^{2} \frac{1}{1 - x ^{2}} d x

\frac{d}{d x} (ln (\frac{1 + cos ( x )}{1 - cos ( x )}))

\int \frac{1}{( x ^{2} - 4 x - 5 )} d x

x^{4} + 2 x, 1
