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

- e^{x} sin (2 e^{x})

Solution steps

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

Apply the chain rule:

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

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

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

= 2 cos (e^{x}) (- sin (e^{x}) e^{x})

Simplify

2 cos (e^{x}) (- sin (e^{x}) e^{x}) : - e^{x} sin (2 e^{x})

= - e^{x} sin (2 e^{x})
