KatClaire Group Title Evaluate the limit one year ago one year ago

1. KatClaire Group Title

$I= \int\limits_{}^{} x^2 \ln (x^2)dx$

2. myininaya Group Title

limit? or integral?

3. KatClaire Group Title

haha oh integral... used to saying limit

4. myininaya Group Title

Use that ln(x^2)=2 ln(x) Then use integration by parts.

5. KatClaire Group Title

okay I'll try that thanks

6. myininaya Group Title

$\int\limits_{}^{}fg'=fg- \int\limits f' g$ Choose the function you take the antiderivative of to be x^2 Choose the function you take derivative of to be ln(x) At the end don't forget to bring that constant multiple 2 down :)
