Hi. I'm wondering how to solve a system of inequalities. I've got five inequalities in three variables that I'd like to find plausible limits for. Is there any way to do this within mathematica? Thanks so much. BTW: I need fairly explicit instructions. My first exposure to Mathematica was this evening and I'm not even sure how to solve a single inequality. I try this, but get: In[15]:= Solve[2 x^2 + x > 3, x] 2 Solve::eqf: Auxiliary[x + 2 x > 3] is not a well-formed equation. Out[15]= 2 Solve[x + 2 x > 3, x] Clearly, I have no idea what I'm doing. Please advise via email. Thanks. ---------- John S. Holmes jsholmes at mit.edu Massachusetts Institute of Technology http://web.mit.edu/jsholmes/ Finger jsholmes at monk.mit.edu for public key.
