integral of xln(x)x

\int x ln (x) x d x

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

Solution steps

\int x ln (x) x d x

Simplify

x ln (x) x : x^{2} ln (x)

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

Apply Integration By Parts

: \frac{1}{3} x^{3} ln (x) - \int \frac{x ^{2}}{3} d x

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

\int \frac{x ^{2}}{3} d x = \frac{x ^{3}}{9}

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

Add a constant to the solution

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

\int x 1 8^{x} d x

\int (5 x^{6} + 3 x^{5} + 5 x^{3} + 4 - e^{x}) d x

\int 12 - x - x^{2} d x

\int \frac{csc ( θ )}{a csc ( θ ) - a sin ( θ )} d θ

\int \frac{3 x + 2}{( x - 3 ) ^{2}} d x
