integral of 1/((1-x)x^2)

Lösung

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

Lösung

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

Schritte zur Lösung

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

Ermittle den Partialbruch von

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

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

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

\int \frac{1}{x} d x = ln ∣ x ∣

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

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

Füge eine Konstante zur Lösung hinzu

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