integral of 1/(u^2-u)

Lösung

\int \frac{1}{u ^{2} - u} d u

- ln ∣ u ∣ + ln ∣ u - 1 ∣ + C

Schritte zur Lösung

\int \frac{1}{u ^{2} - u} d u

Ermittle den Partialbruch von

\frac{1}{u ^{2} - u} : - \frac{1}{u} + \frac{1}{u - 1}

= \int - \frac{1}{u} + \frac{1}{u - 1} d u

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}{u} d u + \int \frac{1}{u - 1} d u

\int \frac{1}{u} d u = ln ∣ u ∣

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

= - ln ∣ u ∣ + ln ∣ u - 1 ∣

Füge eine Konstante zur Lösung hinzu

= - ln ∣ u ∣ + ln ∣ u - 1 ∣ + C
