Schritte zur Lösung

\int_{0}^{1} \frac{1}{3 - 2 x} d x

Wende U-Substitution an

= \int_{3}^{1} - \frac{1}{2 u} d u

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

= - \int_{1}^{3} - \frac{1}{2 u} d u

Entferne die Konstante:

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

= - (- \frac{1}{2} \cdot \int_{1}^{3} \frac{1}{u} d u)

Wende die Potenzregel an

= - (- \frac{1}{2} [2 u^{\frac{1}{2}}]_{1}^{3})

Vereinfache

- (- \frac{1}{2} [2 u^{\frac{1}{2}}]_{1}^{3}) : \frac{1}{2} [2 u]_{1}^{3}

= \frac{1}{2} [2 u]_{1}^{3}

Berechne die Grenzen:

23 - 2

= \frac{1}{2} (23 - 2)

Vereinfache

= 3 - 1
