What is the Calculus Tools Application?
The Calculus Tools application (App) is a Concept software application for the TI-89 / TI-92 Plus. Concept software applications are calculatorsoftware application prototypes that demonstrate a new concept area. The Calculus Tools App extends the built-in power of your TI-89 / TI-92 Plus by providing more specialized functionality. Use the Calculus Tools App to investigate applications of differentiation; compare numerical integration techniques; and explore sequences, series, vector calculus, Fourier series, and more. The CalculusTools App is based on programs written or evaluated by CAS (Computer Algebra System) experts and educators Bernhard Kutzler, Bhuvanesh Bhatt, David R. Stoutemyer, Josef Böhm, Ray Barton, Ruth Dover, and Wolfgang Pröpper. We appreciate their contributions and evaluations. Additional documentation for many of the Calculus Tools App features can be found at series.bk-teachware.com. Other teaching andlearning materials written for the TI-89 and TI-92 Plus are also available at the Web site, including Exploring Integration with the TI-89/92/92+ by Josef Böhm and Wolfgang Pröpper.
