integral of (xln(x))/2

\int \frac{x ln ( x )}{2} d x

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

Solution steps

\int \frac{x ln ( x )}{2} d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

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

Apply Integration By Parts

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

Add a constant to the solution

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