1. The problem statement, all variables and given/known data
If a gas is described by Van der Waals eqn (p+a/v^2)(v-b)=kT, find the critical pint p_c, T_c,and v_c
2. Relevant equations
3. The attempt at a solution
Actually this is just one intermediate step I got stuck for my stat mech homework, I don't even know the mathematical definition for critical point(I didn't learn quite well in my thermodynamics course), the only relevant equation I found is in wiki http://en.wikipedia.org/wiki/Critical_point_%28thermodynamics%29, but I don't think it is adequate for my problem.
