At http://mathworld.wolfram.com/LeibnizIntegralRule.html I learned that Integrate[Log[1-2a Cos[x]+a^2],{x,0,Pi}] = 2*Pi*Log[Abs[a]] Mathematica knows how to do this integral, but gives a much more complicated result. Can anyone explain how to use FullSimplify and other transformations to show that the complicated result Mathematica gives is equivalent to the answer above? Thanks, Ted Ersek
