Graham Sutherland / Polynomial's Post

@r they had been teaching it very much as "it's how you determine the slope of the graph" without any applied context and I just couldn't fathom why you would want to know what the gradient was on a graph at a particular x coordinate, let alone why you'd want to find the coordinate where a particular gradient was found, especially given how involved and unintuitive the procedures to do so could be. naturally once I could map it to a physics context it was trivial to understand why the use-case.
