Examples and Tests:

PROBLEM 1 has the solution U(X) = X^2, on the domain [0,1].

PROBLEM 2 has the solution U(X) = X^2*(1-X^2), on the domain [0,1].

PROBLEM 3 has the solution U(X) = X^2, on the domain [0,1].

PROBLEM 4 has the solution U(X)=X-1/4 left of 1/2, and U(X)=X-1/2 to the right of 1/2, on the domain [0,1]. This problem was devised to study the behavior of singularities.

PROBLEM 5 has the solution U(X) = 1+X, on the domain [0,1]. This problem was devised for a simple accuracy check.
