integral of x^2*ln(x^2)

Lösung

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

\frac{2}{3} x^{3} ln (x) - \frac{2 x ^{3}}{9} + C

Schritte zur Lösung

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

Wende die partielle Integration an

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

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

= \frac{1}{3} x^{3} ln (x^{2}) - \frac{2 x ^{3}}{9}

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

= \frac{2}{3} x^{3} ln (x) - \frac{2 x ^{3}}{9}
