= 5 \cdot \int_{6}^{7} \frac{1}{5 u} d u

Entferne die Konstante:

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

= 5 \cdot \frac{1}{5} \cdot \int_{6}^{7} \frac{1}{u} d u

Nutze das gemeinsame Integral :

\int \frac{1}{u} d u = ln (∣ u ∣)

= 5 \cdot \frac{1}{5} [ln ∣ u ∣]_{6}^{7}

Vereinfache

5 \cdot \frac{1}{5} [ln ∣ u ∣]_{6}^{7} : [ln ∣ u ∣]_{6}^{7}

= [ln ∣ u ∣]_{6}^{7}

Berechne die Grenzen:
