integral of ln(x)(x)

\int ln (x) (x) d x

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

Solution steps

\int ln (x) x d x

Apply Integration By Parts

: \frac{1}{2} x^{2} ln (x) - \int \frac{x}{2} d x

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

\int \frac{x}{2} d x = \frac{x ^{2}}{4}

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

Add a constant to the solution

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

\int x^{3} cos (x y) d y

\int \frac{x ^{2}}{2} + C d x

\int \frac{4}{x ^{3}} + \frac{2}{x} d x

\int \frac{2 x ^{2}}{x ^{3} + 8} d x

\int 2 x (x^{2} + 11)^{4} d x
