** Using WeBWorK **

Thanks Davide,

Of course I can't take any credit for this as "my" code, since I inherited many problems from existing libraries. As I said on the thread with Mike that I thought you were included on, it was dated 12-31-01, long before I was using webwork. It was just a nice problem that behaved nicely through last fall semester and doesn't now.

Thanks again for letting a newbie know how to fix and optimize it, and of the expanded capabilities. :-)

Bob
