I think that's a completely different issue that deserves its own thread if
you want to open it.

The *to_poly_solve* package already generates results like this:

%solve([sin(x)=1/2],x);
%union([x = 2*%pi*%z1380+(5*%pi)/6],
       [x = 2*%pi*%z1419+%pi/6])

Simplifying expressions involving multiple %zNNN's is a challenge....
