New issue 2669 by [email protected]: geometry solve results are thrown away
when symbolic
http://code.google.com/p/sympy/issues/detail?id=2669
No solution is returned from the following because the symbolic terms don't
pass the is_zero test with True or False:
e1 = Ellipse(Point(0, 0), 5, 10)
e2 = Ellipse(Point(x, y), 4, 8)
e1.intersection(e2)
[]
If None is allowed to pass then the solution can be obtained and values
substituted in later. (GeometryEntity needs a better subs routine to allow
for more than a single old, new pair, however.)
Both of these are addressed in https://github.com/sympy/sympy/pull/582
