derivative of

cos (ln (x))

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

Solution steps

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

Apply the chain rule:

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

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

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

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

Simplify

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

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