WebbO This is the most basic proof technique. O By using laws, definitions, and theorems you can get from A to B by starting at A and ... Inductive Proof Example Prove the following: 2n > n for all nonnegative integers . Inductive Proof Solution Proof: Let n = 0. Thus 20 = 1 > 0, and the statement WebbProof: See problem 2. Each person is a vertex, and a handshake with another person is an edge to that person. 4. Prove that a complete graph with nvertices contains n(n 1)=2 edges. Proof: This is easy to prove by induction. If n= 1, zero edges are required, and 1(1 0)=2 = 0.

As in simple induction, we have a statement P(n) P ( n) about the whole number n n, and we want to prove that P(n) P ( n) is true for every value of n n. To prove this using strong induction, we do the following: The base case. We prove that P(1) P ( 1) is true (or ...
