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

Lösung

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

Lösung

- ln ∣ x - 1 ∣ + ln ∣ x - 2 ∣ + C

Schritte zur Lösung

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

Ermittle den Partialbruch von

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

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

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

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

= - ln ∣ x - 1 ∣ + ln ∣ x - 2 ∣

Füge eine Konstante zur Lösung hinzu

= - ln ∣ x - 1 ∣ + ln ∣ x - 2 ∣ + C
