WebStrong induction is a type of proof closely related to simple induction. As in simple induction, we have a statement P(n) P ( n) about the whole number n n, and we want to … WebFor example, the following definition defines fn f n for all n ∈N n ∈ N. fn = 1 if n = 0, fn = nfn−1 if n > 0, f n = 1 if n = 0, f n = n f n − 1 if n > 0, We prove by induction that fn = n! f n = n. Let P () P () denote the predicate “ = f n = n. We prove by induction that P ( P ( holds for all n ∈. Basis. When n= n =, n = n = 1 by definition.
