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

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

Solution steps

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

Apply the Quotient Rule:

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

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

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

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

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

Simplify

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

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

n = 1 \sum \infty \frac{n}{8 ^{n}}

\frac{\partial}{\partial y} (y sin (x z))

x^{2} y y^{^{'}} = e^{y}

y^{^{'}} = y^{2} - 3

y = x^{2} - 4 x, y = 2 x
