Hi,
I was wondering if it's possible to solve nodal analysis problems that include rectangle and polar form using the TI84. It just gives me an error when I put in "i" as in imaginary when trying to put up my matrix. I've read it's possible to do with the TI89, but I'd really rather not spend the money if it's possible to do on my current calculator. For example the TI89 has the "∠" sign which the TI84 doesn't seem to have, except for the "5e^(90i)" etc which isn't really something I want to use in bigger problems. Thanks in advance!

I have a TI86 and it does complex matrices, but these guys:
http://freemathhelp.com/forum/viewtopic.php?f=6&t=25182 say that the TI84 Plus can't do it, so probably the regular TI84 can't either.

To solve a matrix with polar or rectangular elements in TI84, is unlikely possible. I use TI89 Titanium to solve this kind of problem. Or if you have access to matlab, you can use it to solve the problem.

Nodal analysis with TI84
Scilab is also a very capable Matlablike suite developed by a huge French Government team. It's FREE! and very well supported.
