Re: Complex plotting


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.

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
