(\partial)/(\partial x)(1/((1+x)^2))

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

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

Solution steps

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

Apply exponent rule:

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

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

Apply the chain rule:

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

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

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

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

Simplify

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

\frac{d}{d x} (\frac{x ∣ x ∣}{2})

\frac{60}{x}

\int \frac{1}{9 - x ^{2}} d x

\int e^{- k N x} d x

y = A x^{2} + B e^{2 x}
