integral of (e^x)/((e^x+1)^{11)}

\int \frac{e ^{x}}{( e ^{x} + 1 ) ^{11}} d x

- \frac{1}{10 ( e ^{x} + 1 ) ^{10}} + C

Solution steps

\int \frac{e ^{x}}{( e ^{x} + 1 ) ^{11}} d x

Apply u-substitution

= \int \frac{1}{u ^{11}} d u

Apply the Power Rule

= - \frac{1}{10 u ^{10}}

Substitute back

u = e^{x} + 1

= - \frac{1}{10 ( e ^{x} + 1 ) ^{10}}

Add a constant to the solution

= - \frac{1}{10 ( e ^{x} + 1 ) ^{10}} + C
