WebbIn calculus, induction is a method of proving that a statement is true for all values of a variable within a certain range. This is done by showing that the statement is true for the first term in the range, and then using the principle of mathematical induction to show that it is also true for all subsequent terms. Webb(c) Paul Fodor (CS Stony Brook) Mathematical Induction The Method of Proof by Mathematical Induction: To prove a statement of the form: “For all integers n≥a, a property P(n) is true.” Step 1 (base step): Show that P(a) is true. Step 2 (inductive step): Show that for all integers k ≥ a, if P(k) is true then P(k + 1) is true:

WebbAlso, it’s ne (and sometimes useful) to prove a few base cases. For example, if you’re trying to prove 8n : P(n), where n ranges over the positive integers, it’s ne to prove P(1) and P(2) separately before starting the induction step. 2 Fibonacci Numbers There is a close connection between induction and recursive de nitions: induction is ...
