$\huge \bold {\red {\underline{ \underline{\mathfrak{ANSWER}}}}} \red{ :}$

$\star \: \: \underline \blue{solution} \blue{ : }$

$\bold{\frac{d}{dx} ( {e}^{x} + cos \: x)}$

$\longrightarrow \: \frac{d}{dx} {e}^{x} + \frac{d}{dx} cos \: x$

$\longrightarrow \: \huge\boxed {\mathfrak{{e}^{x} - sin \: x}}$

$\bold {\bold{\boxed {\boxed{///MARK \: IT \: BRAINLIEST///}}}}$
