derivative of

\frac{1}{1 - x}

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

Solution steps

\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}}

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

x \to 0 lim (\frac{cot ( 2 x )}{csc ( x )})

f (x) = x^{2} + 8, at x = 1

f (x) = x^{2} + 3, at x = - 3

(e^{x} + 1)^{2}
