derivative of

x^{2} - \frac{1}{2} cos (x)

2 x + \frac{1}{2} sin (x)

Solution steps

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

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (x^{2}) - \frac{d}{d x} (\frac{1}{2} cos (x))

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

\frac{d}{d x} (\frac{1}{2} cos (x)) = - \frac{1}{2} sin (x)

= 2 x - (- \frac{1}{2} sin (x))

Simplify

= 2 x + \frac{1}{2} sin (x)

f (x) = (x^{4} + 3) (- 4 x^{5} + 5 x^{4} + 5)

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

u

\frac{d}{d x} (\frac{1}{1 + 2 x})

\int (x + 4) ln (x) d x
