Schritte zur Lösung

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

Wende die partielle Integration an

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

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

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

Berechne die Grenzen:

2 ln (2) - \frac{3}{4}

= 2 ln (2) - \frac{3}{4}
