Share an engineering (or other) application of an infinite series. Identify it in math notation, an image of a graph, or in a clear explanation in the context of the application. You do not need to explain the entire topic, only identify the infinite series within this application, and tell us some of what it helps to accomplish here.
But how did the calculator know it?
In fact, we take modern computational conveniences for granted. The hand calculator (or the corresponding app) is a fantastic product of engineering; and in this exercise, we’re going to apply one of the techniques they use to calculate square roots:
