Introduction to Maple
Our discussion will focus on Maple 7, which was developed by Waterloo Maple Inc.
in Waterloo,
Ontario, Canada. Quoting from the
Maple 7 Learning Guide
, “Maple is a
Symbolic Computation System
or
Computer Algebra System
. Both phrases refer to Maple’s ability to manipulate information in a symbolic
or algebraic manner.
Conventional mathematical programs require numerical values for all variables.
By
contrast, Maple maintains and manipulates the underlying symbols and expressions, as well as evaluates
numerical expressions.” From the second description you see why Maple is designated as a ‘CAS’.
Assignment Format
We are going to begin by establishing a format for each Maple assignment that is to be handed in. Open
Maple and obtain a blank worksheet. Do not type the “
<
” or “
>
” which are shown to identify your entries.
And
<
Enter
>
means the “Enter” key. As you begin, the worksheet is in “math mode”, so ‘click’ on the
T
to switch into “text mode”.
For the assignment
C2M1
, type
<
C2M1
> <
Enter
>
and then highlight C2M1 and click on the middle
of the three boxes to the right of
B
I
u
so as to center C2M1. The left of these three buttons leftjustifies
text and the right one rightjustifies it. Now,
<
down arrow
>
, then type your name and section as shown.
<
Midn Your Name
> <
Enter
>
<
Section
> <
Your section
> <
Enter
>
Having completed this, highlight the three lines and then click on
B
to boldface everything. This is the
format you should use for all Maple assignments to be handed in. For example, you should see something
like

Beginning Maple Syntax
Because we are building the foundation for the use of Maple, we will designate this spadework by
♠
when we wish to highlight an important fact.
Since getting online help is extremely important, we will
begin with that. Suppose that you have a question about the command ‘plot’. Then in a worksheet enter
<
?plot
> <
Enter
>
and you will see the information available and links for other related topics.
♠
To obtain online help on ‘command’, enter
<
?command
> <
Enter
>
.
You may eliminate the brackets on the left by pressing the function key
<
F9
>
.
To return to math
mode, click on the
[
>
. If we wanted to type a math formula while in text mode we would click on
Σ
.
Later in this section we will discuss
palettes
which allow you to select commands from a menu and avoid
using Maple syntax. It is the contention of the author of these notes that learning some Maple syntax is
beneficial to the student, so even though you may accomplish the same things by clicking on a symbol, we
will show you the syntax that would otherwise be hidden.
In math mode, lines in Maple end with a semicolon or colon.
♠
If a line ends with a semicolon, then the output will be displayed.
