integral of x/(x-3x+2)

Lösung

\int \frac{x}{x - 3 x + 2} d x

\frac{x ^{2}}{- 2 x + 2} - \frac{1}{2} (ln ∣ x - 1 ∣ - \frac{1}{x - 1}) + C

Schritte zur Lösung

\int \frac{x}{x - 3 x + 2} d x

Vereinfache

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

Wende die partielle Integration an

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

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

= \frac{x ^{2}}{- 2 x + 2} - \frac{1}{2} (ln ∣ x - 1 ∣ - \frac{1}{x - 1})
