(d^2)/(dx^2)(1/(1+x))

Solution

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

Solution

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

Solution steps

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

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

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

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

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