The TI-89 Calculator is incredibly powerful but is difficult to use out of the box. The manual provided is hard to read at best and for most students quite confusing. This 8 Hour comprehensive 3-DVD course teaches you how to use all of the major Algebra and Graphing functions of the TI-89 graphing calculator by working example problems. You'll learn how to use the calculator by watching its usage on the screen. In this way, the student "learns-by-doing" rather than a long dry lecture or with the "aid" of a dry printed manual. Future DVD sets will cover the calculus functions and more advanced usage of the TI-89!
