Wende die partielle Integration an

= [\frac{1}{2} (x^{2} ln (11 x) - 2 \cdot \int \frac{x}{2} d x)]_{0}^{\frac{1}{11}}

\int \frac{x}{2} d x = \frac{x ^{2}}{4}

= [\frac{1}{2} (x^{2} ln (11 x) - 2 \cdot \frac{x ^{2}}{4})]_{0}^{\frac{1}{11}}

2 \cdot \frac{x ^{2}}{4} = \frac{x ^{2}}{2}

= [\frac{1}{2} (x^{2} ln (11 x) - \frac{x ^{2}}{2})]_{0}^{\frac{1}{11}}
