derivative of

cos^{2} (x)

- sin (2 x)

Solution steps

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

Apply the chain rule:

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

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

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

= 2 cos (x) (- sin (x))

Simplify

2 cos (x) (- sin (x)) : - sin (2 x)

= - sin (2 x)

\int 5^{x} ln (5) d x

\int_{- π}^{π} cos^{2} (3 x) d x

\int_{- 1}^{22} 21 x - (x^{2} - 22) d x

\int 4 x + 2 d x

\frac{d}{d x} (\frac{1}{2} e^{x^{2}})
