- \frac{ln ( x )}{x + 1} + ln ∣ x ∣ - ln ∣ x + 1 ∣ + C

Schritte zur Lösung

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

Wende die partielle Integration an

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

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

= - \frac{ln ( x )}{x + 1} - (- ln ∣ x ∣ + ln ∣ x + 1 ∣)
