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

with(plots):

**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

?help

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).
