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

1 - 2 sin (x)

Solution steps

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

Apply the Sum/Difference Rule:

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

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

\frac{d x}{d x} = 1

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

= 1 - 2 sin (x)

x^{2} - 2 x + 8

\int x^{5} 1 + x^{3} d x

x^{2} + 4 x - 11 = - 2 y^{2} - 3 y, (2, - 1)

\int (3 - x)^{- \frac{1}{2}} d x

\frac{d}{d x} (x^{2} + x + 4)
