# Can a CASIO CFX-9850GB Plus calculator solve simultaneous equations involving complex numbers?

by tommy like sound on March 14, 2012Q: Hi, I own a CASIO CFX-9850GB Plus calculator and would like to be able to use it to solve simultaneous equations involving complex numbers. While I can call up the “i” in run mode:

OPTN, CPLX, i

I cant do the same in the solver mode or in the matrix mode.

Is it possible? If it’s not, can you recommend a calculator that can do this?

Cheers,

Thomas

It has been a while since I have used programmable calculators. I still have a trusty TI-85 on my desk but I know that the calculators have come a long way since then. I would consider asking a math professor, if you know any, as they should have a better handle on what the different ones can do.
