Web2 Weak Mathematical Induction 2.1 Introduction Weak mathematical induction is also known as the First Principle of Mathe-matical Induction and works as follows: 2.2 How it Works Suppose some statement P(n) is de ned for all n n 0 where n 0 is a nonnegative integer. Suppose that we want to prove that P(n) is actually true for all n n 0.
WebJan 5, 2024 · What Doctor Luis is stating here is technically called “ strong induction “, meaning that we are making a stronger assumption than in ordinary “ weak induction “. Usually weak induction is all we need, but sometimes it is easier to do the proof by making the stronger assumption.
