integral-x^2ln(x)

Lösung

integral

- x^{2} ln (x)

- \frac{1}{3} x^{3} ln (x) + \frac{x ^{3}}{9} + C

Schritte zur Lösung

\int - x^{2} ln (x) d x

Entferne die Konstante:

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

= - \int x^{2} ln (x) d x

Wende die partielle Integration an

= - (\frac{1}{3} x^{3} ln (x) - \int \frac{x ^{2}}{3} d x)

\int \frac{x ^{2}}{3} d x = \frac{x ^{3}}{9}

= - (\frac{1}{3} x^{3} ln (x) - \frac{x ^{3}}{9})

Vereinfache

= - \frac{1}{3} x^{3} ln (x) + \frac{x ^{3}}{9}
