derivative of

cos (8 x)

- sin (8 x) \cdot 8

Solution steps

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

Apply the chain rule:

- sin (8 x) \frac{d}{d x} (8 x)

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

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

= - sin (8 x) \cdot 8

\frac{s}{( s - 3 ) ^{2}}

\int (x^{2} + x)^{13} (2 x + 1) d x

\int (t)^{\frac{1}{2}} d t

\int tan (6 x) (sec (6 x))^{2} d x

\int 8 sin (x) d x
