Note that *Maple* returns either nothing or an unevaluated function call
when *fsolve* fails to find a solution. Adjusting the range within
which solutions are being sought (see the assignment sheet for syntax...)
will typically solve this problem. If someone is not finding the solutions
they seek, check via evaluation whether a solution is really expected in
the region specified.

Observe that the following are mathematically very different:

- fsolve({g},{y},{y=100..200}); (same as g=0)
- fsolve({g=constant},{y},{y=100..200});

Some of the syntax examples use values like x=1, y = 2 which are purely for illustrative purposes. People need to use the real values.

The regular class assignment also includes some problems
"use a computer to..." These can be done with *Maple*, or in some case *Surfaces*.
Show people how to use the sample "Using Maple" worksheets below
*Maple V R3:Math 213*.

Remember *Surfaces* does not always print reasonably, so
shift to screen dumps when that arises.
