integral of ln(13x)

\int ln (13 x) d x

x ln (13 x) - x + C

Solution steps

\int ln (13 x) d x

Apply Integration By Parts

= x ln (13 x) - \int 1 d x

\int 1 d x = x

= x ln (13 x) - x

Add a constant to the solution

= x ln (13 x) - x + C

\int - e^{- x} sin (x) d x

\int x^{3} (7 + x^{4})^{7} d x

\int \frac{x ^{2}}{( 2 x - x ^{2} )} d x

\int 60 x d x

\int \frac{1}{x ( 3 x + 5 )} d x
