This was a fun Desmos graph to whip up, helping a student make the connection between rectangular and polar functions. desmos.com/calculator/ptp… #MTBoS #ITeachMath

Had fun making a surface/contour map/gradient generator in Desmos 3D with my Multivariable students today. This one's easily customizable. desmos.com/3d/2cff48b448 #MTBoS #ITeachMath

Whipped up a nice parametric plot (complete with grid curves) for a fun surface in Desmos. #MTBoS #ITeachMath desmos.com/3d/3c3edc7636

Who do I know at the Anja S. Greer Math and Technology conference at Exeter this year? #MTBoS #ITeachMath

So long, and thanks for all the fish.
