1. The problem statement, all variables and given/known data Evaluate the Definite Integral Integral[0,1] Ln(x^2+1) dx 2. Relevant equations 3. The attempt at a solution So far I have done the first part, U= Ln (x^2+1) Du= 2x/(x^2+1)dx Dv= 1 dx V=x x* Ln(x^2+1)- Integral [0,1] (2x^2/(x^2+1) dx But I'm stuck on the second integral, I have tried punching into a TI-89, but It comes out to a weird answer. Can someone help?
