APPENDIX A

A MAPLE Primer

This section is intended to assist students in using MAPLE. In some cases, examples are given
which can be easily adapted to general use. Additional examples and details can be found in
MAPLE’s HELP function. The student should experiment with the code given here and expand
and adapt it to personal needs and preferences. In many instances, it is also possible to write
different instructions to carry out computations.

A.1 Beginning Computations

Numerical computations are carried out as one might expect, with an asterisk * denoting a
product and a wedge ∧ a power. If we type
2∧ 14;
we obtain the fourteenth power of 2, which is 16,380. Note the semicolon ending this MAPLE
command. In some versions of MAPLE, semicolons are used to end commands. In later releases,
the semicolon is not needed. However, if the semicolon is included, the command will still
execute.
14
To multiply 2 by 19, type
∗
19 2∧14;
π is stored in MAPLE as Pi (upper case P—MAPLE is case sensitive). The exponential
function is denoted exp, and the number e is obtained as exp(1). If we enter
∗
(Pi ∧ 2) exp(1);
this will return the symbolic product
2
(π )e
To obtain the (approximate) decimal value of this product, use the evalf command:
∗
evalf((Pi ∧ 2) exp(1));
