derivative of

3 x^{2} - 2 cos (x)

6 x + 2 sin (x)

Solution steps

\frac{d}{d x} (3 x^{2} - 2 cos (x))

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (3 x^{2}) - \frac{d}{d x} (2 cos (x))

\frac{d}{d x} (3 x^{2}) = 6 x

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

= 6 x - (- 2 sin (x))

Simplify

= 6 x + 2 sin (x)
