The Use of Graphing Calculator in Teaching and Learning Transformations, Polar Curves and Matrices

Abstract

This is a sharing on how graphing calculators can be used in the teaching of ??level topics both involving and not involving graphs. To explore graphing functions, specific examples are given using transformation of graphs and polar coordinates. With some scaffolding and guidance on calculator keystrokes, students are encouraged to explore how graphs can be translated, scaled and reflected. Students also learn to appreciate the beauty and diversity of polar curves. The use of graphing calculators further builds up students?confidence as they check their answers for areas bounded by polar curves. In non-graphing topics like matrices, an example on how graphing calculators can be used in application problems to stimulate students?interest in Mathematics will be discussed.
