Cartesian equation - Study guides, Class notes & Summaries

Proof by Exhaustion Prove the statement by checking each element individually. Unlike proof by cases, exhaustive proof looks at every case in a way that is not general. Proof by Counterexample Used to disprove a universal statement. For example, to disprove the statement, "All prime numbers are odd" find one example where this statement is false—the number 2—which is both even and prime. Direct Proof In the direct proof, we assume the hypothesis p is true and we try to pro...
