A Beautiful trick for Functional Equations| Putnam 1988 A5

Описание к видео A Beautiful trick for Functional Equations| Putnam 1988 A5

In today's video I go over a very nice trick for functional equations that I don't think is very common (at least I haven't seen it used before). This problem comes from A5 of Putnam 1988 and it actually inspired the last problem on the 1989 APMO. Perhaps several other functional equations can be done by this trick and I'm definitely going to create some olmypiad level problems with this now
