\frac{d}{d x} (\frac{5}{( 2 x ) ^{3}} + 2 cos (x))

- \frac{15}{8 x ^{4}} - 2 sin (x)

Solution steps

\frac{d}{d x} (\frac{5}{( 2 x ) ^{3}} + 2 cos (x))

Simplify

\frac{5}{( 2 x ) ^{3}} + 2 cos (x) : \frac{5}{8 x ^{3}} + 2 cos (x)

= \frac{d}{d x} (\frac{5}{8 x ^{3}} + 2 cos (x))

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (\frac{5}{8 x ^{3}}) + \frac{d}{d x} (2 cos (x))

\frac{d}{d x} (\frac{5}{8 x ^{3}}) = - \frac{15}{8 x ^{4}}

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

= - \frac{15}{8 x ^{4}} - 2 sin (x)

y = x^{2} 3 x + 5

\frac{d}{d x} ((\frac{5}{3}) x^{2})

\int (4 x)^{2} d x

\int_{4}^{8} t^{2} ln (3 t) d t

\int \frac{1}{6 x ( 3 + x )} d x
