Hello,
Is there a way to manage a long symbolic solution?
Any simplification command?
Thank you,
Basile

I understand what you are trying to do, but useless on two counts:
1. Soon, the symbolic expansion is not manageable, especially on cheap calculators.
2. Those things solve from universal solvers, very fast [revisit the recent Tridiagonal].

Jean,
I thought that perhaps there is a way to display the symbolic solution. If it is possible... Perhaps force the answer to wrap...
Yes, I can solve numerically, but thanks for the alternative idea.
Thanks,
Basile

A 2x2 system is OK
A 3x3 almost not possible. Mathcad wrapping not easy.
A 4x4 ... forget it, Mathcad can't expand, above work sheet capacity.
