Strong induction vs inductive proof
WebTo make this proof go through, we need to strengthen the inductive hypothesis, so that it not only tells us \(n-1\) has a base-\(b\) representation, but that every number less than or … WebA proof of the basis, specifying what P(1) is and how you’re proving it. (Also note any additional basis statements you choose to prove directly, like P(2), P(3), and so forth.) A statement of the induction hypothesis. A proof of the induction step, starting with the induction hypothesis and showing all the steps you use.

WebWith simple induction you use "if p ( k) is true then p ( k + 1) is true" while in strong induction you use "if p ( i) is true for all i less than or equal to k then p ( k + 1) is true", … WebOutline for Mathematical Induction. To show that a propositional function P(n) is true for all integers n ≥ a, follow these steps: Base Step: Verify that P(a) is true. Inductive Step: Show that if P(k) is true for some integer k ≥ a, then P(k + 1) is also true. Assume P(n) is true for an arbitrary integer, k with k ≥ a .
