Diana, I tried to reply to you privately by sending some gif images of the function made with my Cardano2 package from my web site. But the first time I forgot to remove from your email address and the second time I either removed too much or not enough so that didn't go either. So if you want the images send me your actual email address and I'll send them to you. I was able to make a number of nice plots of the function including a vector plot animation and I will send the notebook to anyone who wants to see them and who has the Cardano2 package. David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ From: Diana [mailto:diana53xiii at earthlink.remove13.net] To: mathgroup at smc.vnet.net Mathematica folks, I am trying to plot the function: E^(3 z)/(1 + E^z) where z ranges from z = R (>0) to z = R + 2 Pi I. When z = R, the value of the function is E^(3 R)/(1 + E^R) When z = R + Pi I, the value of the function is E^(3 R)/(-1 + E^R) When z = R + 2 Pi I, the value of the function is E^(3 R)/(1 + E^R) again. I am trying to show with a plot that the magnitude of the function achieves its maximum at z = R + Pi I. I have tried using ComplexMap, but perhaps don't know how to fully utilize it. Help would be appreciated. Diana -- ===================================================== "God made the integers, all else is the work of man." L. Kronecker, Jahresber. DMV 2, S. 19.
