integral of (sqrt(x))/((1+x)^2)

integral

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

- \frac{x}{1 + x} + arctan (x) + C

Solution steps

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

Apply Integration By Parts

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

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

= - \frac{x}{1 + x} - (- arctan (x))

Simplify

= - \frac{x}{1 + x} + arctan (x)

Add a constant to the solution

= - \frac{x}{1 + x} + arctan (x) + C
