= [x arctan (x) - \int \frac{x}{x ^{2} + 1} d x]_{- 2}^{3}

\int \frac{x}{x ^{2} + 1} d x = \frac{1}{2} ln x^{2} + 1

= [x arctan (x) - \frac{1}{2} ln x^{2} + 1]_{- 2}^{3}

Berechne die Grenzen:

3 arctan (3) - 2 arctan (2) + \frac{- ln ( 10 ) + ln ( 5 )}{2}

= 3 arctan (3) - 2 arctan (2) + \frac{- ln ( 10 ) + ln ( 5 )}{2}
