derivative of 2cos(x+cos(2x))

Solution

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

Solution

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

Solution steps

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

Apply the Sum/Difference Rule:

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

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

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

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

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