For any sets S, T, consider the claim that (Sx T) n (T x S) - (S × S) = 0. Consider the proof that supposes (Sx T) (T × S) - (S × S) ‡ Ø and wants to show that ³x : [x € (S× T) ^ x ‡ (T × S)]. True or False: This is a valid proof approach that would prove the claim. (This is not asking whether this is an actual proof of the result. It's asking whether this general, high-level approach would suffice to prove the result.)
