網頁Example 1: Use mathematical induction to prove that \large {n^2} + n n2 + n is divisible by \large {2} 2 for all positive integers \large {n} n. a) Basis step: show true for n=1 n = 1. {n^2} + n = {\left ( 1 \right)^2} + 1 n2 + n = (1)2 + 1 = 1 + 1 = 1 + 1 = 2 = 2 Yes, 2 2 is divisible by 2 2. b) Assume that the statement is true for n=k n = k. 網頁Every problem that can be solved by using the standard mathematical induction can be solved by the generalized strong induction. In fact, it is almost always easier to use the generalized strong induction because in the inductive step, there are more inductive hypotheses that we can use. Task5.12

Strong Induction

網頁2024年8月9日 · In "strong induction", the inductive step is a bit more liberal. (1') If P ( i) is true for all m ⩽ i ⩽ n then, P ( n + 1) is true. In both inductions you need to then prove … 網頁2024年7月7日 · Strong Form of Mathematical Induction. To show that P(n) is true for all n ≥ n0, follow these steps: Verify that P(n) is true for some small values of n ≥ n0. Assume … 網頁2024年3月19日 · For the base step, he noted that f ( 1) = 3 = 2 ⋅ 1 + 1, so all is ok to this point. For the inductive step, he assumed that f ( k) = 2 k + 1 for some k ≥ 1 and then tried … god is here today youtube
