Technology Tutorials

Generally, the tutorials listed in the table below focus on features of graphing devices, examples of how they can be used to solve problems, and appropriate use. They are far from comprehensive. Becoming proficient with graphing technology requires experience with problem-solving as well as technical issues.

There are four main graphing tools (beside the human eye and hand) in use in the NRG math department: graphing calculators, Winplot, Mathematica, and ODE Architect. Winplot is a free program that you can download at http://math.exeter.edu/rparris/. (It's still less than 1MB.) The tutorial on Matrices uses another program, Winmat, which like Winplot is free and can be obtained at the same site. (Thanks, Richard.) Unfortunately, these programs are currently PC only.

Other Resources

Math Department Graphing Technology Page - good departmental information.
Technical Math - AWLs home page for a companion website for one of their books. Still, good basics in tutorials 1 - 4.
TI Student Site - I think the guidebooks are pretty good.

Note: The first link is being repaired.
