Maple inserts the eval command calling sequence that performs the substitu-
tion. This is the most common use of the eval command.
For example, substitute in the following polynomial.

To substitute a value for a variable using palettes:
1. In the Expression palette, click the evaluation at a point item .
2. Specify the expression, variable, and value to be substituted.
For example:

Substitutions performed by the eval function are syntactical, not the more
powerful algebraic form of substitution.
If the left-hand side of the substitution is a name, Maple performs the substi-
tution.
