Some people I was working with noticed that the following integrate fails to give the correct result Pi: In[1]:= Integrate[Exp[I x] Cos[x],{x,0,2 Pi}] Out[1]= 0 Any ideas why? This happened on a NeXT running Mathematica 1.2. Howard Lee Dept of Applied Physics Stanford University howardl at leland.stanford.edu
