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

e^{x} + sin (x)

Solution steps

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

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

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

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

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

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

Simplify

= e^{x} + sin (x)
