I've decided to drop the last few terms, those of degree higher than 5. I tried to assign zero to but that gave me a syntax error. Then I tried to substitute zero for but that only zeroed the term. Maple only allows assignment to names. I don't see the matrix.
Matrices are a special type of an array.
If they are named, the name only evaluates to itself but, it points to the matrix data structure. The most common way of producing a high-quality paper copy of a graph is through PostScript. Here's an example of how to do this. It can then be printed on any PostScript printer. The actual command to send the file to the printer varies from system to system.
