derivative

cos (2 x) \cdot 2 - sin (2 x)

Solution steps

\frac{d}{d x} (sin (2 x) + cos^{2} (x))

Apply the Sum/Difference Rule:

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

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

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

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

= cos (2 x) \cdot 2 - sin (2 x)
