integral of (ln(x+1))/(\sqrt[3]{x+1)}

Lösung

\int \frac{ln ( x + 1 )}{3 x + 1} d x

Lösung

\frac{3}{2} (x + 1)^{\frac{2}{3}} ln (x + 1) - \frac{9}{4} (x + 1)^{\frac{2}{3}} + C

Schritte zur Lösung

\int \frac{ln ( x + 1 )}{3 x + 1} d x

Wende U-Substitution an

= \int \frac{ln ( u )}{3 u} d u

Wende die partielle Integration an

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

\int \frac{3}{2 u ^{\frac{1}{3}}} d u = \frac{9}{4} u^{\frac{2}{3}}

= \frac{3}{2} u^{\frac{2}{3}} ln (u) - \frac{9}{4} u^{\frac{2}{3}}

Setze in

u = x + 1

ein

= \frac{3}{2} (x + 1)^{\frac{2}{3}} ln (x + 1) - \frac{9}{4} (x + 1)^{\frac{2}{3}}

Füge eine Konstante zur Lösung hinzu

= \frac{3}{2} (x + 1)^{\frac{2}{3}} ln (x + 1) - \frac{9}{4} (x + 1)^{\frac{2}{3}} + C
