Without giving away too much “insider info”, at my current job I’m working on some software that models the interaction of some different 1-dimensional surfaces. I represent these surfaces using splines, which are piece-wise polynomial functions. When I need to know the y-position of a surface at a given x-position, I evaluate the appropriate polynomial at that x-position to find it.
I’m curious what you were using this for. (I haven’t found a use for a lot of my mathematical knowledge at that level so far.)
