integral of xln(x^2)

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

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

Solution steps

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

Apply Integration By Parts

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

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

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

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

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

Add a constant to the solution

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

\frac{d}{d x} (x^{3} I n x)

x \to 0 lim (x - \frac{1}{x - 1})

\int 100 e^{0.2 x} d x

\int_{4}^{9} \frac{x - x}{x} d x

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