Good time friends,
Recently, I saw this link http://math.stackexchange.com/q/613753/8581. There we asked to find the functions f(x) ang g(x) by having both composition functions fog(x) and gof(x). I know what to do to find any of f(x) (or g(x)) if I am given fog(x) (or gof(x)) respectively, but I confess I don't know what to do with this one. Can Maple overcome this knid of problem? Thanks for your time.
