derivative of

f (x) = x cos (x) + 2 tan (x)

cos (x) - x sin (x) + 2 sec^{2} (x)

Solution steps

\frac{d}{d x} (x cos (x) + 2 tan (x))

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (x cos (x)) + \frac{d}{d x} (2 tan (x))

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

\frac{d}{d x} (2 tan (x)) = 2 sec^{2} (x)

= cos (x) - x sin (x) + 2 sec^{2} (x)
