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

\frac{ln ( 1 + x )}{1 + x} = ln (1 + x) \frac{1}{1 + x}

= \int_{0}^{2} ln (1 + x) \frac{1}{1 + x} d x

Wende U-Substitution an

= \int_{0}^{l n (3)} u d u

Wende die Potenzregel an

= [\frac{u ^{2}}{2}]_{0}^{l n (3)}

Berechne die Grenzen:

\frac{ln ^{2} ( 3 )}{2}

= \frac{ln ^{2} ( 3 )}{2}
