integral of [pln(p)]

\int [p ln (p)] d p

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

Solution steps

\int p ln (p) d p

Apply Integration By Parts

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

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

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

Add a constant to the solution

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