Ti 89, Solving multiple equations with complex numbers

Click For Summary

Discussion Overview

The discussion centers around solving multiple equations involving complex numbers using the cSolve method on the TI-89 calculator. Participants explore issues related to syntax and variable usage in the context of this specific problem.

Discussion Character

  • Homework-related

Main Points Raised

  • One participant describes their attempt to use the cSolve method with specific equations but encounters an error message regarding too many arguments.
  • Another participant expresses frustration and questions whether solving such equations is possible on the TI-89.
  • A third participant suggests that the user should ensure the correct format for complex numbers, indicating that the proper format is a + b*i rather than a + b*J.
  • The original poster responds, noting that their calculator does not allow the use of 'a' and 'b' as algebraic variables, but other variables work without issue.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the issue, as there are differing experiences regarding variable usage and the correct syntax for complex numbers.

Contextual Notes

There may be limitations related to the specific model of the TI-89 calculator and its handling of variable names and complex number formats, which remain unresolved.

Homework Statement


So, I know how to solve multiple equations using the cSolve method on the ti 89, but for some reason when I try to solve the following...

80a + 240b = 0 and (80+J79.975)a-80b = 50 by using the following syntax...


cSolve(80a + 240b = 0 and (80+J79.975)a-80b = 50 ,{a,b})

I get a message saying that there are too many arguments, what am I doing wrong?

Can anyone helpme with this? I am not having any luck at all, is this even possible?
 
When all else fails, try reading the instructions.

The proper complex number has a format of a + b*i, not a + b*J
 
I know that haha, as it turns out, in my calculator for some reason you cannot use a and b as algebraic variables, it works perfectly fine using any other variable XD
