integral of t(arctan(t))

Lösung

\int t (arctan (t)) d t

\frac{1}{2} t^{2} arctan (t) - \frac{1}{2} (- arctan (t) + t) + C

Schritte zur Lösung

\int t arctan (t) d t

Wende die partielle Integration an

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

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

= \frac{1}{2} t^{2} arctan (t) - \frac{1}{2} (- arctan (t) + t)
