ANSWER CHECKS AND DETAILS.
The maple code segments for problem 1 can be used for answer checks,
but they do not count toward the handwritten portion of the exam
in #1 (a) or #1 (b). Credit is applied to (a), (b) according to the
handwritten detail, references to the text, and logical sequence.
Too many cases earn a demerit as do too few cases.

USING MAPLE.
Beware of using maple to "solve" problem 1. It cannot do it by itself.
Maple by default assumes a variable combination is nonzero when it
encounters a possible divide by zero situation. This assumption is never
printed by maple's engine, and for problems such as this one, that means
that maple will find only some of the possible answers. In fact, maple
finds just one answer, and it does not attempt to find any others. There
are more answers, of course. The answer check methods using maple have to 
pay attention to maple's limitations. This is done by delivering to maple
specially prepared matrices, in which we control the possible divide by
zero possibilities.

USING MATLAB.
Is matlab better? No, it does not handle variable names by default. To do
symbolic computation with matrices, matlab's engine passes the task onto
the maple engine (licensed with matlab). All problems cited above still
exist with matlab.
