derivative of

cos (x) - sin (2 x)

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

Solution steps

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

Apply the Sum/Difference Rule:

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

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

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

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

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