suppose A is a set of formulas and every finite subset of A is satisfiable, then A is satisfiable.?
prove this
satisfiable means that for every finite subset of A, there is a unique truth assignment that will make the subset of formulas true.
also, why is the intersection of the finite subsets and the truth assignments nonempty?
this is for my Math 451 class at UNLV
