derivative of

cos (x)

- \frac{sin ( x )}{2 x}

Solution steps

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

Apply the chain rule:

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

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

\frac{d}{d x} (x) = \frac{1}{2 x}

= - sin (x) \frac{1}{2 x}

Simplify

- sin (x) \frac{1}{2 x} : - \frac{sin ( x )}{2 x}

= - \frac{sin ( x )}{2 x}

\int 3 x^{2} cos (7 x) d x

\int 9 x d x

\int_{0}^{20} 2^{\frac{t}{10}} d t

\frac{\partial}{\partial x} (- 2 + e^{- x} cos (y))

\frac{10}{5 x}
