derivative of

f (x) = \frac{x ^{3} - 2 x + 5}{x ^{3}}

\frac{4 x - 15}{x ^{4}}

Solution steps

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

Apply the Quotient Rule:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

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

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

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

= \frac{( 3 x ^{2} - 2 ) x ^{3} - 3 x ^{2} ( x ^{3} - 2 x + 5 )}{( x ^{3} ) ^{2}}

Simplify

\frac{( 3 x ^{2} - 2 ) x ^{3} - 3 x ^{2} ( x ^{3} - 2 x + 5 )}{( x ^{3} ) ^{2}} : \frac{4 x - 15}{x ^{4}}

= \frac{4 x - 15}{x ^{4}}

\frac{d}{d x} (9 x^{2} + 4)

\int 3 x \frac{2}{x} d x

\frac{\partial}{\partial y} (40 x + 840 - 40 y)

\int 2 x + e^{x} d x

\int (ln (x)) d x
