Comment #10 on issue 3699 by [email protected]: solve() should be able to
tell you when it knows it's found all the solutions
http://code.google.com/p/sympy/issues/detail?id=3699
Yes, None is necessary, because we will always have algorithms that are
heuristic (we don't know if they get all the solutions or not). The
algorithm works conservatively. It splits the expression apart
multiplicatively (factoring), and does a fuzzy all on the solutions
returned by each factor.
A UnknownSolution class, which would generalize RootOf to non-polynomials,
would be useful. How would evalf work, though? We have to know at least
something about the solution we want to numerically evaluate it (to make
sure we get the right one). Anyhow, I think that's a separate issue.
