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 calculator software 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 Calculus Tools 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 and learning 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.
