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

2 - cos (2 x) \cdot 2

Solution steps

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

Apply the Sum/Difference Rule:

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

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

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

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

= 2 - cos (2 x) \cdot 2
