integral of ln^2(3x)

Lösung

\int ln^{2} (3 x) d x

Lösung

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

Schritte zur Lösung

\int ln^{2} (3 x) d x

Wende die partielle Integration an

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

\int 2 ln (3 x) d x = 2 (x ln (3 x) - x)

= x ln^{2} (3 x) - 2 (x ln (3 x) - x)

Füge eine Konstante zur Lösung hinzu

= x ln^{2} (3 x) - 2 (x ln (3 x) - x) + C
