In Response To 'Re: FindRoot not sovling a nonlinear system of ...'
Thanks, but it didn't work either. The system of equations is coming from the first order conditions of an optimization problem, so they were derived symbolically. I think that's what is giving my trouble, but I haven't find a solution. I used 'Mathematica 4' before, and I'm not being able to translate to the current version my old codes.
