Experiments in Mathematics Using Mathematica

Introduction

We believe that to understand and be comfortable with mathematical concepts and methods, it is necessary to do mathematics and, traditionally, doing meant with a pencil and paper. Now, quite a modest home computer can provide a platform for a powerful computer algebra package like Mathematica, which can perform all of the operations encountered in high school mathematics and beyond, and provide graphical representations of functions, including animations.

The capability of rendering very accurate graphics for mathematical functions greatly enhances the learning experience, and helps intuition work in new situations, before beginning to do the algebra and calculus needed to solve a problem. For example, if you can see that a function has a clear minimum from its graph, then you are more likely to be able to identify its location precisely by analysis.

Availability of Interactive Notebooks

The interactive Mathematica notebooks that we have developed for the two senior high school years are available at

Outline and Organization

They take you from basic algebra, functions and sequences, to calculus and its applications. The notebooks are live documents and allow addition of your own examples and explorations---just like a traditional exercise book---so you can expand the study of any particular themes that interest you, adding more topics, graphs and animations. Each of our notebooks contains open-ended experiments with some hints for project work. In fact, all mathematics on a computer is experimental mathematics and we hope that you get in the habit of trying to check results by analytic methods!

In a number of the notebooks we have included animations of families of functions to illustrate the role of parameters, you will easily find ways to develop these animations for your own interests.

The software Mathematica is provided in many schools, colleges and universities, and student editions are available at low cost. Moreover, Mathematica is one of the standard mathematical packages used by working scientists, engineers and teachers.
