3.1: An Introduction to Proof Techniques
3.2: Direct Proofs
3.3: Indirect Proofs
3.4: Mathematical Induction - An Introduction
Mathematical induction can be used to prove that an identity is valid for all integers n≥1 .
3.5: More on Mathematical Induction
Besides identities, we can also use mathematical induction to prove a statement about a positive integer n . Induction can also be used to prove inequalities, which often require more work to finish.
