derivative of

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

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

Solution steps

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

Apply exponent rule:

\frac{1}{a} = a^{- 1}

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

Apply the chain rule:

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

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

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

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

Simplify

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

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