WebTactic 1 is called weak induction; tactic 2 is called strong induction. Spot the difference from the point of view of asking a domino why it is falling. Weak induction: "I'm falling because the domino before me has fallen." Strong induction: "I'm falling because all the dominoes before me have fallen." Trivially, every statement provable by ... WebInduction. The principle of mathematical induction (often referred to as induction, sometimes referred to as PMI in books) is a fundamental proof technique. It is especially useful when proving that a statement is true for all positive integers n. n. Induction is often compared to toppling over a row of dominoes. WebApr 17, 2024 · In a proof by mathematical induction, we “start with a first step” and then prove that we can always go from one step to the next step. We can use this same idea to define a sequence as well. We can think of a sequence as an infinite list of numbers that are indexed by the natural numbers (or some infinite subset of $\mathbb{N} \cup \{0\})$. costco optical east lyme ct
