Here is a explanation by example: Let's say you have the following formula that you want to prove: sum (i i <- [1, n]) = n * (n + 1) / 2. This formula provides a closed form for the sum of all integers between 1 and n. We will start by proving the formula for the simple base case of n = 1. In this case, both sides of the formula reduce to 1. george washington grave picsWebTo explain this, it may help to think of mathematical induction as an authomatic “state-ment proving” machine.
