WebJan 6, 2015 · Here is the entire example: Strong Induction example: Show that for all integers k ≥ 2, if P ( i) is true for all integers i from 2 through k, then P ( k + 1) is also true: Let k be any integer with k ≥ 2 and suppose that i is divisible by a prime number for all integers i from 2 through k. We must show that. WebInductive Step : Prove the next step based on the induction hypothesis. (i. Show that Induction hypothesis P(k) implies P(k+1)) Weak Induction, Strong Induction. This part was not covered in the lecture explicitly. However, it is always a good idea to keep this in mind regarding the differences between weak induction and strong induction.
WebA proof by induction consists of two cases. The first, the base case, proves the statement for = without assuming any knowledge of other cases. The second case, the ...

WebProof by induction is a way of proving that a certain statement is true for every positive integer \(n\). Proof by induction has four steps: Prove the base case: this means … WebA stronger statement (sometimes called “strong induction”) that is sometimes easier to work with is this: Let S(n) be any statement about a natural number n. To show using strong induction that S(n) is true for all n ≥ 0 we must do this: If we assume that S(m) is true for all 0 ≤ m < k then we can show that S(k) is also true.
WebProof by mathematical induction: Example 3 Proof (continued) Induction step. Suppose that P (k) is true for some k ≥ 8. We want to show that P (k + 1) is true. k + 1 = k Part 1 + (3 + 3 - 5) Part 2Part 1: P (k) is true as k ≥ 8. Part 2: Add two 3-cent coins and subtract one 5 …
