\frac{d}{d x} (\frac{x ^{4} + 1}{x ^{2} - 1})

\frac{2 x ^{5} - 4 x ^{3} - 2 x}{( x ^{2} - 1 ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{x ^{4} + 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 ^{4} + 1 ) ( x ^{2} - 1 ) - \frac{d}{d x} ( x ^{2} - 1 ) ( x ^{4} + 1 )}{( x ^{2} - 1 ) ^{2}}

\frac{d}{d x} (x^{4} + 1) = 4 x^{3}

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

= \frac{4 x ^{3} ( x ^{2} - 1 ) - 2 x ( x ^{4} + 1 )}{( x ^{2} - 1 ) ^{2}}

Expand

4 x^{3} (x^{2} - 1) - 2 x (x^{4} + 1) : 2 x^{5} - 4 x^{3} - 2 x

= \frac{2 x ^{5} - 4 x ^{3} - 2 x}{( x ^{2} - 1 ) ^{2}}

\int (y \cdot e^{x} + sin (y)) d x

\int_{0}^{π} 6 cos^{4} (x) sin (x) d x

x \to - 0.1 lim (1 + e^{x})

4 y - y^{^{''}} = 10 e^{(- 3 x)}

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