In this brief chapter, you will learn some Maple fundamentals. These include Maple’s command line, arithmetic, and built-in functions. You will learn how to define new functions and how to assign names to Maple objects for storage. We will be limiting ourselves, in this and the next two chapters, to the features that are pertinent to our purpose, on the assumption that the reader will want to begin writing animations as soon as possible. For those who would like a less focused introduction to Maple, the excellent help facility provides one. You will learn how to access that, too.
