\int_{0}^{5} \frac{x}{x ^{2} + 5} d x

Wende U-Substitution an

= \int_{5}^{30} \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_{5}^{30} \frac{1}{u} d u

Nutze das gemeinsame Integral :

\int \frac{1}{u} d u = ln (∣ u ∣)

= \frac{1}{2} [ln ∣ u ∣]_{5}^{30}

Berechne die Grenzen:

ln (30) - ln (5)

= \frac{1}{2} (ln (30) - ln (5))
