derivative of

\frac{x ^{3}}{x + 1}

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

Solution steps

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

Apply the Quotient Rule:

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

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

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

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

= \frac{3 x ^{2} ( x + 1 ) - 1 \cdot x ^{3}}{( x + 1 ) ^{2}}

Simplify

\frac{3 x ^{2} ( x + 1 ) - 1 \cdot x ^{3}}{( x + 1 ) ^{2}} : \frac{2 x ^{3} + 3 x ^{2}}{( x + 1 ) ^{2}}

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

\int 18 e^{x} d x

\int_{0}^{64} \frac{5}{x ^{\frac{2}{3}}} d x

\int_{- \frac{π}{4}}^{0} 8 sec^{3} (x) d x

\frac{\partial}{\partial x} (3 x^{2} + 2 x y + y^{2} - 11)
