一Maple基本介绍
Basic introduction to Maple
Maple 是一个数学软件，透过智能文件界面提供最强大的数学引擎，可以轻松分析、探索、可视化和求解数学问题。
Maple is a math software that provides the most powerful math engine with a smart file interface to easily analyze, explore, visualize and solve math problems.
Solve problems in almost all mathematical fields or related fields that depend on mathematics, with more than 6,000 built-in calculation commands and more than 100 algorithm function packages
Computation, text, graphics, video, sound, and models can be combined in a single file
Easy to learn and easy to use programming language
Create interactive applications
三Maple基本知识
Basic knowledge of Maple
1.常规运算
Normal Operation
[>是 Maple 自动显示的命令行提示符，无需我们手工输入。如要显示输出结果，运算表达式后加“;”；如不要显示输出结果，运算表达式后加“:”。
[> is the command line prompt that Maple automatically displays without our manual input. If you want to display the output result, add “;” after the operation expression; if you don’t want to display the output result, add “:” after the operation expression.
l If you want to delete a single text, you can use the “Del” key; if you need to delete the entire line, you can use the Ctrl+Del key combination, Maple’s “super delete” function key can be used to delete the entire line of complex objects.
When the inputted mathematical expression is long, in order to see the entire mathematical expression in the window, you can stop the cursor after any operator and press the Shift+Enter key combination to make the mathematical expression wrap.
To calculate several mathematical expressions at the same time, there are two methods. One is to add “;” after each mathematical expression, then press Enter or click the Execute button on the toolbar. The second is to enter the mathematical expression and click the button on the toolbar, Maple will perform all the operations in the file.
2.求值
Evaluate
Eval – 对一个表达式求值
eval – 求值
evala – 在代数数（或者函数）域求值
