integral of z^2ln(z)

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

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

Solution steps

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

Apply Integration By Parts

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

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

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

Add a constant to the solution

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

What is the integral of z^2ln(z) ?
The integral of z^2ln(z) is 1/3 z^3ln(z)-(z^3)/9+C
