derivative of

\frac{x ^{3}}{5 - x ^{2}}

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

Solution steps

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

Apply the Quotient Rule:

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

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

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

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

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

Simplify

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

= \frac{15 x ^{2} - x ^{4}}{( 5 - x ^{2} ) ^{2}}

\frac{d}{d x} (\frac{1}{3} x^{3} + 7 x^{2} + 50 x)

\int \frac{y ^{4}}{y ^{2} - 9} d y

\int (1 + sin (x)) d x

\frac{\partial}{\partial x} (2 x^{2} - 3 y^{2} - 2 x)

\frac{\partial}{\partial x} (y^{2} + 1)
