Discrete Mathematics Proof By Case Youtube Discrete math can be a tough course to pass. i'm here to help! this lesson is about proofs of statements in which an "or" statement appears in an assumptio. Introduction to video: proof by cases. 00:00:57 overview of proof by exhaustion with example #1. exclusive content for members only. 00:14:41 prove if an integer is not divisible by 3 (example #2) 00:22:28 verify the triangle inequality theorem (example #4) 00:26:44 the sum of two integers is even if and only if same parity (example #5). 13.1 steps. the steps in a proof by cases are similar to those in a proof by exhaustion: perform a partition of \(p\) into cases. note that a partition of \(p\) into “cases” is similar to the list of possibilities you create for a proof by exhaustion, except that cases are generally more broad (usually containing multiple elements) than each single possibility in a proof by exhaustion. Published dec 19, 2023. contribute to docs. proof by cases is a technique used in mathematical proofs to demonstrate a statement by showing that it is true in each of a set of cases. these cases must be mutually exhaustive, meaning that they cover all possibilities, so that at least one of them must be true. by showing that the statement holds.
