Cnf ::= c | c ∧ cnf. B _ d ) equivalent : Conversion to cnf every formula f in propositional logic can be converted into an equivalent cnf formula f 0: M (f ).

::=l | l ∨ c. Web conjunctive normal form (cnf) is an important normal form for propositional logic. Note that this means that a formula in cnf has no free variables. Compute answers using wolfram's breakthrough technology & knowledgebase, relied on by millions of students &. Then, you write each clause down as a premise or given in your proof.
