A calculation gives me the following as a part of the output that I see on the screen: (i = Imaginary) -0.262484 i Exp[-0.951249 i t] + 0.262484 i Exp[0.951249 i t] I want to apply ExpToTrig and , of course, end up with 0 for the Cosine part and - .262484*2 Sin [0.951249] for the Sine part ... instead I get (which I decided to look at output with InputForm) (-0.2624844042359744*I)*Cos[0.9512492197250393*t] + (0.26248440423597375*I)*Cos[0.9512492197250397*t] - 0.2624844042359744*Sin[0.9512492197250393*t] - 0.26248440423597375*Sin[0.9512492197250397*t] I can see from this that the coefficients and exponent numbers are very close but not identical although , I think, in theory they should be. I'm not worried about the 10th decimal place. How do i get the result I want in a general way? thanks....jerry blimbaum
