Hi,
Couls someone please help me with this question: I have a large list of simultaneous algebraic equations to be solved. I have tried using Solve and Reduce, and they give a list of all possible sets of solutions. However, there is only one correct solution (one in which a certain parameter is positive definite).

Call this parameter k - I have succesfully used Solve like this:

Solve{{eq1,eq2,...eqn,k!=0},vars]

works fine. But I really want something like:

Solve[{eq1,eq2,...eqn,k>0},vars]

Mathematica gives no answer to this. How can one get around this problem?

Thanks
Hiranya
