integral of ln(9sqrt(x))

Lösung

\int ln (9 x) d x

Lösung

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

Schritte zur Lösung

\int ln (9 x) d x

Wende die partielle Integration an

= x ln (9 x) - \int \frac{1}{2} d x

\int \frac{1}{2} d x = \frac{1}{2} x

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

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

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

Füge eine Konstante zur Lösung hinzu

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