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

Schritte zur Lösung

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

Ermittle den Partialbruch von

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

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

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

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

\int \frac{1}{x} d x = ln ∣ x ∣

\int \frac{1}{x ^{2}} d x = - \frac{1}{x}

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

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

Vereinfache

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