Consider the predicate ϕS(x) which abbreviates: Con(ZF) → x = ZF ∧ ¬ Con(ZF) → x = ∅. The predicate ϕS(x) acts as a definition for S and we have ZF ⊢ ∃!xϕS(x). ---- Proof Predicates ----.

Show that if x 3 + 6 x 2 + 12 x + 8 = 0, then x = − 2. The last example demonstrates a technique called proof by cases. There are two possibilities, namely, either (i) x 2 + 1 = 0, or (ii) x − 7 = 0. The final conclusion is drawn after we study these two cases separately. chromophone by aas
