\int_{0}^{3} 6 x ln (x) d x

Entferne die Konstante:

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

= 6 \cdot \int_{0}^{3} x ln (x) d x

Wende die partielle Integration an

= 6 [\frac{1}{2} x^{2} ln (x) - \int \frac{x}{2} d x]_{0}^{3}

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

= 6 [\frac{1}{2} x^{2} ln (x) - \frac{x ^{2}}{4}]_{0}^{3}
