The present technical note concerns a method for obtaining an approximation to weak-weak solutions of equation: < L u - f ,v > = 0. The method leads to a variational principle for the equation, even for cases in which L is not a potential operator and, therefore, violates the usual conditions desired for constructing variational principles.
