Comment #1 on issue 2749 by matt...@gmail.com: subs(Dict) does not work
http://code.google.com/p/sympy/issues/detail?id=2749
This is again the problem we had with tuple and Tuple. We have to carefully
use lower and upper case types.

These functions are mostly targeted toward square roots, which are
basically roots of quadratics (or quartics). When the minimal polynomial
gets bigger, things beco

When you don't tell it what to do, it gives you the first valid solution it
finds. It used to give *all* valid solutions for symbols it

I don't think it would be too hard to, when given less symbols than eqs, to
find some additional variable that would allow the system t

Also, we need to improve the root finder. The root for the above
polynomial should be given as 2 + 3**(1/3), not (-3)**(1/3)*(-1/2 +
sqrt(3)/2*I) + 3**(1/3). You c

Yes, the name should be something like as_nonrelational (except there is
probably a better name than that). as_expr() doesn't make sense as noted
above since

as_expr() doesn't make sense as noted above since Eq is already an Expr.
Poly is an Expr, but it has as_expr() method. Almost everything is an Expr
but there is

I agree and see c17 above which responds to Ronan's previous comment.

I meant Eq(FiniteSet(1, 2), FiniteSet(1, 2, 3)).as_expr(), obviously.

Perhaps, as I indicated before, we can consider this a case of garbage
in garbage out. And why would Eq keep that and not simply return
False?
