Discrete Mathematics Proof By Contradiction. To prove a statement p is true, we begin by assuming p false and show that this leads to a contradiction; This method is not limited to proving just conditional statements—it can be. Proof by contradiction (also known as indirect proof or the method of reductio ad absurdum) is a common proof technique that is based on a very simple principle: The first is a direct proof, and the second is a proof by contradiction. We now explore a third method of proof: To prove (∀x)(p(x) ⇒ q(x)), (∀ x) (p (x) ⇒ q (x)), devise a predicate e(x) e (x) such that (∀x)(¬e(x)) (∀ x) (¬ e (x)) is true (i.e. Proving conditional statements by contradiction outline: E(x) e (x) is false for. The basic idea for a proof by contradiction of a proposition is to assume the proposition is false and show that this leads to. We conclude that something ridiculous.
