WebDiscrete Math in CS Induction and Recursion CS 280 Fall 2005 (Kleinberg) 1 Proofs by Induction Inductionis a method for proving statements that have the form: 8n : P(n), where n ranges over the positive integers. It consists of two steps. First, you prove that P(1) is true. This is called the basis of the proof. WebProof by mathematical induction An example of the application of mathematical induction in the simplest case is the proof that the sum of the first n odd positive integers is n2 —that is, that (1.) 1 + 3 + 5 +⋯+ (2 n − 1) = n2 for every positive integer n.

WebSep 5, 2024 · The strong form of mathematical induction (a.k.a. the principle of complete induction, PCI; also a.k.a. course-of-values induction) is so-called because the hypotheses one uses are stronger. Instead of showing that P k P k + 1 in the inductive step, we get to assume that all the statements numbered smaller than P k + 1 are true.
