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

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

Solution steps

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

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

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

Apply the Quotient Rule:

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

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

\frac{d x}{d x} = 1

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

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

Simplify

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

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

\int_{2}^{5} 3 x^{2} - 4 x d x

\frac{\partial}{\partial y} (54 - \frac{2}{3} x^{2} - 4 y^{2})

n = 1 \sum \infty \frac{n}{e ^{n^{3}}}

cos (- 4 t)

\frac{d}{d x} (sin (x) + \frac{1}{2} cot (x))
