## Homework Statement

Evaluate the Definite Integral

Integral[0,1] Ln(x^2+1) dx

## Homework Equations

## 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?
