Desmos is the on-line graphing calculator available to you during your math SAT. Knowing how to use it will give you an advantage! It does many useful, things, giving you an easier path to solve math problems.
In this first of four short videos, Mr K will show you how to graph, how to change the viewing window and how to find important points on a graph: interepts, local maxima or minima, and intersection points. At the end of the video, you will also see a slightly devious way to solve equations without doing algebra!
