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

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

\frac{2}{3} arctan^{\frac{3}{2}} (x) + C

Solution steps

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

Apply u-substitution

= \int u d u

Apply the Power Rule

= \frac{2}{3} u^{\frac{3}{2}}

Substitute back

u = arctan (x)

= \frac{2}{3} arctan^{\frac{3}{2}} (x)

Add a constant to the solution

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

\int \frac{( x + 1 )}{( x ^{2} - 2 x + 5 )} d x

\int e^{yz} d x

\int \frac{x + x ^{2}}{x} d x

\int (2 - x) x d x

\int \frac{1}{2 x ^{2} + 4 x + 7} d x
