Title Solve n x n Systems of Non-Linear Equations
Description This new version of cSolve_n() finds real and complex solutions of n x n systems of non-linear equations. Some trig equations can be handled, but no more than one unknown angle. The number of equations is no longer limited to 3 and unknowns are not limited to x, y, and z. The program is basically a version of the TI Solve and cSolve functions, but is easier to use (no variable list to enter). Domain restrictions, such as x > 0 or θ > -π and θ ≤ π, can be entered. All entries can be edited. If there are more unknowns than equations, you can choose which to solve for, so symbolic solutions can be found.

This program adds very little to the functionality of your TI-89 as it simply accomplishes exactly what the solve function can do. Not recommended as the program simply takes up memory.
