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

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

Solution steps

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

Apply the Quotient Rule:

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

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

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

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

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

Simplify

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

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

\int cos (mπ x) d x

f (x) = 20 x^{\frac{1}{2}} - \frac{1}{2} x^{20}

12 t^{3} - t^{2}

\frac{d}{d x} (2 x - \frac{4}{x})

\int \frac{2 x ^{3} - 4 x ^{2} - 9 x - 1}{x ^{2} - 2 x - 5} d x
