Freebee Friday: Calculator by the Numbers
Who needs a box full of expensive graphing calculators at $100 each when a PC can do just as well. Maybe, even better because rather than a fuzzy black and white screen, you’re using a bright color display. My favorite at the moment is Runiter’s Graphing 3D 3.2, which is available for PCs, Macs and Linux computers. It’s perfect for graphing functions, including parametric equations and inequalities. Alongside the graph is a table of the coordinates. Unlike other calculators, this one can run full screen so that the subtlety of the graphing comes through. The free basic version should be plenty for most schools, but there is a $50 commercial version as well.
