When explaining the least-squares, why not drawing the damn squares in the chart then?
- shoo 11y agoone of my colleagues was lamenting the fact that he made it all the way through pre-university mathematics education without anyone explaining the geometry link between "x-squared", i.e. "x^2", and the area of a square of side-length x. so this is a pretty reasonable thing to ask for.
- gballan 11y agoAuthor (and Blabr dev) here. I have no answer--other than it seems like a really good idea, now that you've said it. The plotting widget I used is based on flot [0]. It looks like flot can draw simple shapes ([1], see "markings"). I'll look into improving the widget--thanks for the idea.
