\frac{d}{d x} (e^{x} + 2^{- x} + 2 cos (x) - 6)

e^{x} - ln (2) \cdot 2^{- x} - 2 sin (x)

Solution steps

\frac{d}{d x} (e^{x} + 2^{- x} + 2 cos (x) - 6)

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (e^{x}) + \frac{d}{d x} (2^{- x}) + \frac{d}{d x} (2 cos (x)) - \frac{d}{d x} (6)

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

\frac{d}{d x} (2^{- x}) = - ln (2) \cdot 2^{- x}

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

\frac{d}{d x} (6) = 0

= e^{x} - ln (2) \cdot 2^{- x} - 2 sin (x) - 0

Simplify

= e^{x} - ln (2) \cdot 2^{- x} - 2 sin (x)
