derivative of

- \frac{1}{1 - x}

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

Solution steps

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

Take the constant out:

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

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

Apply exponent rule:

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

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

Apply the chain rule:

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

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

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

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

Simplify

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