One of the nice things about Maple V rev 4 is it's assume command. Is there such a thing on Mathematica? Basically I am trying to get a solution to a Fourier transform that I have to calculate by residues by hand, and I would like to see a similar result on the computer. By hand, I need to first assume w (the frequency variable) is less than zero, solve for that, then assume w greater than zero and solve for that. Mathematica gives a real tidy solution to the problem, but doesn't really let me know if what I did was right. Does anyone know how to do this? -laurent baig lbaig at ece.arizona.edu University of Arizona ==== [MESSAGE SEPARATOR] ====
