Then I use 'Eliminate' and the algebraic equations to eliminate some variables. However, 'Eliminate' does not get rid of one of the variables I point to. I am sure it is possible to elimilate it. Who knows the reason? Thanks > Hum, without seeing the equations (or a similar but simpler example) it is hard to tell. I encourage you to post the set of equations (or even better if this is possible, a small example showing the same behavior), the Mathematica command you used, and any messages returned by Mathematica (do not forget to use the *ImputForm*).
