derivative of

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

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

Solution steps

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

Take the constant out:

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

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

Apply exponent rule:

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

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

Apply the chain rule:

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

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

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

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

Simplify

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

\frac{d}{d x} (3 x^{2} - x + 12)

\int_{0}^{7} \frac{8 x}{( x - 8 ) ^{2}} d x

\int t^{\frac{1}{2}} d t

y = arctan (x^{2})

\int_{- \infty}^{- 1} e^{- 14 t} d t
