Schritte zur Lösung

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

Ermittle den Partialbruch von

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

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

\int \frac{2}{x} d x = 2 ln ∣ x ∣

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

\int \frac{2}{x - 1} d x = 2 ln ∣ x - 1 ∣

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

= 2 ln ∣ x ∣ - \frac{1}{x} - 2 ln ∣ x - 1 ∣ - \frac{1}{x - 1}

= 2 ln ∣ x ∣ - \frac{1}{x} - 2 ln ∣ x - 1 ∣ - \frac{1}{x - 1} + C
