Winplot is a free graphing utility that was written by Richard Parris, a math instructor at Phillips Exeter Academy in Exeter, New Hampshire. Sadly Richard passed away in 2012. After Richard's death the program WinPlot was still available for a number of years on the Exeter Academy math department's web site. Working versions of winplot and winstats (a simple to use statistical analysis package) can be intalled on a Windows operating system by right clicking on the links below. This will download a zipped version of the program to be installed on a directory of your choosing. Click on Run and the program will display a destination directory of c:/peanut. You can change this to any valid directory name which, if it does not already exist, will be created when the Unzip command is issued. For use on Madison College computers you should probably change the directory to be on your H: drive. Once the program WinPlot is installed you can create a shortcut to it on your desktop.

Obviously, Winplot allows you to customize the parameters of all equations. You can modify the value of X, Y and Z; in number of divisions, the cut points and define the quality of the representation.

In addition to generating and graphing functions, Winplot includes two additional functions. A planetary orbit generator to calculate trajectories of objects in space and a test series that will help you assess your knowledge.
