Well, I've used that: arg = something solutions = solve(sin(arg)) solutions_trig = [(sol - pi) for sol in solutions] as I remember, sin is fine with it because at [-1, 1] it's mirroring itself at (0, 0) for most functions. среда, 27 ноября 2013 г., 0:43:03 UTC+4 пользователь Aaron Meurer написа

Hi All, I want to change the basic organization of Diophantine equation module so that it can be extended and used more conveniently. Since I wish to develop the module for CSymPy also, I thought this would be a good time to talk about this. Currently, the Diophantine module is invoked through th
