Discussing functions can be a tricky endeavor, but having a handy interactive way to talk about functions can relieve a great deal of stress. As part of the Mathematical Sciences Digital Library, this Functions Grapher application is designed to let users enter one or two functions. After doing so, users can trace along either one with coordinates shown dynamically changing at all times. The...

Hosted through the mathematics department at Furman University, this website offers "a collection of mathematical quotations culled from many sources." The quotation database can be searched for by keyword, browsed by last name, randomly generated or viewed in its entirety. Some quotes are long while others are short and may be attributed to an anonymous person, but all have something to do with...

This website has a wealth of resources on game theory and its applications to economics, business, political science, computer science, and other disciplines. Some of the resources include links to journals, associations, teaching resources, and major web portals. From the links provided, visitors can read about the history of game theory, experiment with games that demonstrate key concepts in a...

Economics professor, Ariel Rubinstein, created this website to provide teachers some basic instruction in Game Theory along with "free user-friendly didactic tools for conducting web-based thought experiments." The materials are based on his experience in teaching a course in Game Theory using web-based experiments during the years 1988 to 1999. Sample problems are available in five languages:...

This resource for educators and students of game theory aims to make lessons on game theory more relevant to the student (see also NSDL Scout Report for Math, Engineering, and Technology, October 11, 2002). This section of the website provides links to lecture notes for courses in game theory and applied game theory offered by faculty at various universities. The collection is arranged in a table...
