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

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

Solution steps

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

Apply the Sum/Difference Rule:

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

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

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

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

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

f (x) = (1 - x^{3}) + (1 - x^{3})

6 (x^{3} + 4)^{3}

\frac{d}{d x} (- 7 sin (\frac{x}{7}))

y = (x^{2} + 7 x + 1)^{3}
