Hi Everyone,
Chris, perhaps another approach is possible. For most mathematical
problems, there are constructions possible that verify the answer.
For example: when solving a system of equations, it is easy to
implement a function that calculates each equation given the answers
provided by the students and checks the answers.
{Default example from solve? below}
x, y = var('x, y')
solve([x^2+y^2 == 1, y^2 == x^3 + x + 1], x, y)
==> verify that the answers are exactly what the students answer..
This simple example is perhaps not very good, solve might give the
students a hint how to solve the problem automatically, but you get
the yest of it..
