OK thanks for this, bug reported [at least, I think it is. I couldn't see it on trac].
Now what about this: sage: solve(sin(x) + cos(x) == cos(2*x),x,to_poly_solve=True) [x == 2*pi*z264, x == 2*pi*z268 + 1/6004799503160661*I - 355/452, x == 2*pi*z266 + 1/1125899906842624*I - 355/226, x == 2*pi*z270 + 1/9007199254740992*I + 1065/452] After the first, the solutions are not actually solutions of the equation. Is this reportable or have I misunderstood what solve() is supposed to do?
