Curve Fitting as an Intro to Machine Learning

I created a slide deck in 2019 to help people like me who may have forgotten some of their Calculus to get an understanding of Least Squares curve fitting, and its similarities with Machine Learning algorithms. I will continue to add to the project contents, below, over time.
