Sawtooth Functions. Classroom Notes
Hirst, Keith
International Journal of Mathematical Education in Science and Technology, v35 n1 p122-126 Jan 2004
Using MAPLE enables students to consider many examples which would be very tedious to work out by hand. This applies to graph plotting as well as to algebraic manipulation. The challenge is to use these observations to develop the students' understanding of mathematical concepts. In this note an interesting relationship arising from inverse trigonometric functions is analysed. To understand what is going on students have to develop an understanding of how to deal with inverses where a function is not 1-1, by restricting the domain. The piece of work developed here also provides some interesting exercises in proof by induction.
