RE: more robust programming of alternate correct responses (maple-graded)
You can use Maple's StringTools library to convert both the response and teachers answer to lower case before comparing them. You then need to parse the lowercase string to turn it back into math.
In Grading Code:
$TA = "2*Pi*R*t*L*rho";
Note, make sure you use text entry mode with this as the symbolic editor is weird with Pi.
