Appendix C: The Essentials of Maple

In this appendix, we will review some of the basic Maple operations used in this book. Maple has a very helpful feature of providing context-sensitive help. That means that if you forget how a command is used, or even what the command is, simply type the word and click on it.

Throughout this book we have used the worksheet mode of Maple version 10.0. The commands will work in version 10.0 or any later version. In 2012 version 16.04 is current.

To make an assignment like a: =3*x+4, use := to assign 3 * x + 2 to the symbol a. The equation a=3*x+4 is made with the equal sign and not colon equal. ...
