Graphing
Recently, we have been flooded with emails from people telling us how much they love GraphCalc. We’ve assembled a handful of their testimonials here.
History of GraphCalc
In January of 1999 GraphCalc started as a project to keep us occupied when we were not busy with other commitments. We have been working hard on it, some say too hard, to make a simple and easy to use graphing calculator for windows that is rich in features.
If the Windows calculator just isn’t getting the job done, or you don’t want to pay $100 for a little monochrome display handheld calculator, download GraphCalc for free and see for yourself how easy it is to graph an equation or find out what 345.4327 is in binary!
