Indeed, it is THE question to ask because curvature is everything we need to know about a curve (modulo some annoying *groups* we will talk about in the future). If you are too shy to ask, you can *compute* it and that is what this post is about. In order to compute the curvature you need a bunch of things and for each one there is a bunch of ways of doing it, so, let’s talk about some of them.
