![]() There are also a number of plotting words, which are used to draw graphs of functions of one or two variables, curves and surfaces. There is a large vocabulary of Maple words, such as factor, simplify, and expand which are used to 'symbolically manipulate' expressions in the manner you are used to doing with pencil and paper. That means that it is built to work with algebraic expressions and draw pictures. It is a symbolic and graphical manipulator: If the command is terminated with a semicolon (colon), the output is displayed (not displayed). The result of performing the procedure on the input is naturally called the 'output' of the word. That stuff is usually called the 'input' of the word. These are names of procedures which have been defined for performing the action (sometimes) suggested by the name on the stuff enclosed in parentheses just after the word. The strings factor and expand are called Maple 'words'. Tells Maple to do a sequence of three things: add 2 and 5, factor the quadratic, and expand the binomial. A Maple command is simply a string of characters ending in a semicolon ' ' or colon ':'. That means that you can type in commands and execute them, just like in the languages Basic and Logo. Maple has at least four properties which make it very useful in problem solving. You may be using an earlier release on a different platform, but most of what is in this document is still relevant. ![]() The particular version of Maple that we are using as we describe it is Maple 9 running in Windows XP or 2000. Here we intend to provide you with just enough information about the Maple language to give a headstart at using it productively in the problem solving process.
