Discrete math strong induction examples

WebFor the next two examples, we will look at proving every integer \(n>1\) is divisible by a prime. Although we proved this using cases in Chapter 4, we will now prove it using induction. First we will attempt to use regular induction and see why it isn't enough. Example 5.4.1. Trying Regular Induction.

discrete mathematics - Mathematical Induction vs Strong Induction ...

WebNote: Compared to mathematical induction, strong induction has a stronger induction hypothesis. You assume not only P(k) but even [P(0) ^P(1) ^P(2) ^^ P(k)] to then prove P(k + 1). Again the base case can be above 0 if the property is proven only for a subset of N. Richard Mayr (University of Edinburgh, UK) Discrete Mathematics. Chapter 5 11 / 20 WebExamples - Summation Summations are often the first example used for induction. It is often easy to trace what the additional term is, and how adding it to the final sum would affect the value. Prove that 1+2+3+\cdots +n=\frac {n (n+1)} {2} 1+2+ 3+⋯+ n = 2n(n+1) for all positive integers n n.
