    In the spirit of fun and collaboration, I set out to create graphs that brought together my favorite online math tools. G(x) is GeoGebra and D(x) is Desmos (thanks to the folks at Desmos for the title concept). With encouragement from my GeoGebra tweep, John, and shading help from my Desmos tweeps, Mary , Bob, and Marc, I am happy to share with you, G(D(x)) and D(G(x)).

    Here are the GeoGebra and Desmos files if you want to “look under the hood!” G(D(x)) and D(G(x))


    After teaching for 14 years, I now design curriculum and create digital and print instructional materials for high school and middle school math. I have also invented and am now marketing radian-scale protractors. Check out www.proradian.net! I'm very happily married and have 2 grown sons and a cat named Louie.
