Schritte zur Lösung

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

Wende U-Substitution an

= \int_{2}^{0} - \frac{1}{u} d u

\int_{a}^{b} f (x) d x = - \int_{b}^{a} f (x) d x, a < b

= - \int_{0}^{2} - \frac{1}{u} d u

Entferne die Konstante:

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

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

Wende die Potenzregel an

= - (- [2 u^{\frac{1}{2}}]_{0}^{2})

Vereinfache

- (- [2 u^{\frac{1}{2}}]_{0}^{2}) : [2 u]_{0}^{2}

= [2 u]_{0}^{2}
