RE: Plotting complex numbers
No, unfortunately, to my knowledge, only real functions can be plotted.
That would be a nice addition though, if the imaginary parts could be plotted as well for complexvalued functions . . .

RE: Plotting complex numbers
I think you can use the RE() and IM() commands in the Function App like this:
to give this plot I think your example only shows imaginary values. Other expressions of interest to plot using RE(), IM() might include: 100/(X*(1+i)) i^X exp^(i*X) Thanks for asking this! The Prime seems pretty useful for exploring real, imaginary functions this way.

I didn't think about IM() because it was somewhat unreliable (together with sqrt) in the previous firmware http://www.hpmuseum.org/forum/thread646.html but that appears to have been fixed in version 6030!
