integral of (x^3ln(sqrt(x)))/3

Lösung

\int \frac{x ^{3} ln ( x )}{3} d x

Lösung

\frac{1}{3} (\frac{1}{8} x^{4} ln (x) - \frac{x ^{4}}{32}) + C

Schritte zur Lösung

\int \frac{x ^{3} ln ( x )}{3} d x

Entferne die Konstante:

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

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

Wende die partielle Integration an

= \frac{1}{3} (\frac{1}{4} x^{4} ln (x) - \int \frac{x ^{3}}{8} d x)

\int \frac{x ^{3}}{8} d x = \frac{x ^{4}}{32}

= \frac{1}{3} (\frac{1}{4} x^{4} ln (x) - \frac{x ^{4}}{32})

\frac{1}{4} x^{4} ln (x) = \frac{1}{8} x^{4} ln (x)

= \frac{1}{3} (\frac{1}{8} x^{4} ln (x) - \frac{x ^{4}}{32})
