Did you know that Desmos can do many other things besides simply graphing functions? Desmos can also deal with implicitly defined functions, perform algebraic manipulation, and animate functions. In this session we show some of the interesting ways we use Desmos in our Algebra 2, Precalculus, Math Models, and Calculus classes. In addition to ideas on how to use Desmos in their secondary math classrooms, participants will also be shown how to find and search the many previously made Desmos lessons.
