hp 33s / 35s - solving simultaneous 2 variable linear equations with complex coefficients Message #1 Posted by Smalle on 16 Nov 2008, 9:00 p.m. Is there a program for the hp33s / 35s similar for solving simultaneous equations having two variables using complex number coefficients? The 33s manual provides a program for 3 variable with real coefficients, and suggests replacing specfic coefficients with 0s and 1s while using it to solve for 2 variables. That method is not very convenient, and it would be convenient to have some way to switch between solving for two variable or three variables; whether for real or complex. Palmer O. Hanson, Jr. in this forum has developed programs for solving 3 variable simultaneous equations with complex coefficients using the hp33s/35s. Are there similar programs for 2 variables as well.

Re: hp 33s / 35s - solving simultaneous 2 variable linear equations with complex coefficients Message #2 Posted by bill platt on 16 Nov 2008, 9:28 p.m., in response to message #1 by Smalle Am I missing something, or what? Why can't you adjust the 3 variable to a 2 variable routine? It would seem conceptually to be a trivial task.
