Proofs by induction. An important technique for showing that a statement is true is “proof by induction.” We shall cover inductive proofs extensively, starting in Section 2.3. The following is the simplest form of an inductive proof. We begin with a statement S(n) involving a variable n; we wish to Basis prove that S(n) is true.
