Greetings, I would like to simplify an expression involving Pi. Actually, simplifying the expression isn't hard, getting Mathematica to recognize the simplification is the hard part. Consider: Assuming[Element[x, Reals], FullSimplify[Log[1/Sqrt[2 Pi] Exp[x]]]] Mathematica doesn't do anything to simplify this. However, replacing the symbol Pi with any other variable in the above leads to the trivial substitutions. By trivial, I mean: Log[Exp[x]] = x, and Log[a/b] = Log[a] - Log[b]. Why does Pi confuse Mathematica so?? Thanks, -Chris
