Proofs by induction ivolving sets

WebThis process, called mathematical induction, is one of the most important proof techniques and boils down a proof to showing that if a statement is true for k, then it is also true for k + 1. We devote this chapter to the study of mathematical induction. 6.1.2 Formalizing Mathematical Induction WebThe proposition P(n) for our induction is then “For any set S containing n elements, S has 2n subsets.” Notice that each P(k) is a claim about a whole family of sets, e.g. P(1) is a claim about {37}, {fred}, {−31.7}, and so forth. Proof: We’ll prove this for all sets S, by induction on the cardi-nality of the set. 5

WebThis shows that P(n + 1) is true and finishes the proof by induction. The two sets are disjoint if n + 1 = 2. In fact, the implication that P(1) implies P(2) is false. As you can see, induction used improperly can prove ridiculous things. Often times the mistakes are subtle. It takes a good understanding of induction to use it correctly.
