a Grading object
The GetExpression command returns an expression that obj represents, if this exists, followed by any variables used in the expression. Otherwise nothing is returned.
If obj was not created with user-supplied variables, then automatically generated variables may appear in the returned result.
L ≔ LinearFunction⁡0,5,3,−2:
Q ≔ QuadraticFunction⁡w2−2⁢w+5
Q≔<< QuadraticFunction: w^2-2*w+5>>
The Grading:-GetExpression command was introduced in Maple 18.
