I've opened http://trac.sagemath.org/sage_trac/ticket/14738 for a lot of
this stuff. It's all related to keywords not being sufficiently happy.

If solve() gives an unspecificed integer, how do I substitute a
particular value into the expression?
subs() does not work as expected/desired because the free variables
don't seem to be defined.
sage: a=solve(sin(x)==0,x,to_poly_solve='force')

If solve() gives an unspecificed integer, how do I substitute a
particular value into the expression?
subs() does not work as expected/desired because the free variables
don't seem to be defined.
sage: a=solve(sin(x)==0,x,to_poly_solve='force');a
[x == 2*pi
