integral of tln(t)

\int t ln (t) d t

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

Solution steps

\int t ln (t) d t

Apply Integration By Parts

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

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

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

Add a constant to the solution

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