Maple has a lot of silly ways of doing things. Here's some things for Maple users to consider:
1. Each equation should end in a semicolon (Maple
displays results) or a colon.
If you end your calculation in a semicolon, Maple will display the results. If you end in a colon, Maple does calculation, but doesn't display result. Putting a colon at the end of a plot command if you want it "commented out." Another strategy is to always use semicolons so that you can confirm Maple is doing what you think it's doing. After you have everything working, replace semicolons with colons on lines which produce unnecessary output.
2. Inserting Text.
To insert text instead of an equation, hit the big "T" button. Text lines do not need to end in a colon or semicolon.
3. Include Libraries with "with" command
For example, to include the plot library, try
4. 3 and 3.0 are different
In maple (as in C or C++) a 3 is a scalar constant, and unless you tell it otherwise, Maple will try to try to do symbolic calculations. The number 3.0 on the other hand, is a floating point number, and Maple will generally use finite precision arithmetic. Maple is at constant war with itself (and you) because it's always trying to figure out whether to do calculations symbolically or numerically. One of the challenges in authoring Maple code is to get Maple to produce a number, when it solved your problem symbolically.
5. Getting Help from Maple.
One of the simplest ways to get help from Maple is to type a question mark followed by the word you want help on. For example, try typing in
You can also highlight the word help, go the the "help menu", and click on "help on".
6. SAVE, SAVE, SAVE!!!
Maple has a very nasty habit of unexpectedly terminating. Save your work to the student folder every 5 minutes or so.
7. Maple is Touchy.
Syntax must be exactly correct, one symbol out of place, and Maple has no idea of what you want. Unfortunately, Maple doesn't complain much, so it won't necessarily tell you it doesn't understand something.
8. Note to Mac Users.
The Enter key and the Return key work differently on a Mac. Maple will only process lines when the Enter key is used.
9. Where's the graphs?
If your computer won't print graphs, try changing the number of colors (in the operating system) to 256 instead of "millions."
10. It's as easy as 3.1415926535897932384246
If you want Maple to recognize the number pi, use Pi (capital P, lowercase i).
