Schritte zur Lösung

\int_{0}^{1} \frac{2 x}{( 2 - x ) ^{2}} d x

Entferne die Konstante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 2 \cdot \int_{0}^{1} \frac{x}{( 2 - x ) ^{2}} d x

Wende die partielle Integration an

= 2 [\frac{x}{2 - x} - \int \frac{1}{2 - x} d x]_{0}^{1}

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

= 2 [\frac{x}{2 - x} - (- ln ∣ 2 - x ∣)]_{0}^{1}

Vereinfache

= 2 [\frac{x}{2 - x} + ln ∣ 2 - x ∣]_{0}^{1}

Berechne die Grenzen:

1 - ln (2)

= 2 (1 - ln (2))
