Feb 11, 2014 - Explore Rosemary Caroline's board "Geometry Help", followed by 115 people on Pinterest. I'm going to define a function S of n and I'm going to define it as the sum of all positive integers including N. And so the domain of this function is really all positive integers - N has to be a positive integer. This is what I'm assuming. And then we're going to do the induction step, which is essentially saying "If we assume it works for some positive integer K", then we can prove it's going to work for the next positive integer, for example K + 1. To demonstrate the power of mathematical induction, we shall prove an algebraic equation and a geometric formula with induction. In this post I’ll be proving to you that if: a/b=c/d. Algebraic Proofs. Such as: Direct, Contraposiive, Contradiction, Induction, etc. Now what I want to do in this video is prove to you that I can write this as a function of N, that the sum of all positive integers up to and including N is equal to n times n plus one, all of that over 2.
