Hello everybody!
Can I do calculations with complex numbers that are defined only by

sage: var("R1 X1 R2 X2")
sage: Z1 = R1 + X1*i
sage: Z2 = R2 + X2*i
sage: Z = Z1 + Z2
sage: print Z
sage: Z.imag()

Why? Is Sage
Hi,
Maybe the following is of some interest. Last week, I was in both
Beijing and Shanghai. The main webpages www.sagemath.org as well as
http://groups.google.com/group/sage-support could be used, but no

Hi,
I'm thrilled that a new VMware version is out. But looking at
METALINK, I found version 4.5.2 for win while other versions are
4.5.1? See www.sagemath.org/mirror/win/meta/sage-vmware-4.5.2.zip.
