integral of 1/(x^2-x^3)

Lösung

\int \frac{1}{x ^{2} - x ^{3}} d x

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

Schritte zur Lösung

\int \frac{1}{x ^{2} - x ^{3}} d x

Ermittle den Partialbruch von

\frac{1}{x ^{2} - x ^{3}} : - \frac{- x - 1}{x ^{2}} - \frac{1}{x - 1}

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

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