Summary:
The symbolic pocket calculator TI-92 was used during math lessons at the Stiftsgymnasium Wilhering, a privat high school near Linz in Austria, during the last year. The students were at the age of 17. The different modes of representation (table, graph, algebraic expression) allow to introduce the concepts of calculus in a very natural and illustrative way. In the lecture different possiblities of how to introduce the concepts of analytic geometry and calculus are presented. The TI-92 was also used during tests. We report about the new modified abilities required from the students especially during tests.
