Famous problem.
Discussed Here.
(But I have an embarassing Trigonometry Solution!)
But there is a link on page #2 that provides another solution.
Can I post a problem please? Since I answered red_dog's solution.
See Here
Sorry, I'm gonna have to ask if you can post another problem.
This is because some people wants to take part (and we dunno what their level is).
There're some hard problems but not so hard like this one.
Plus, this is starting, and the level of problems must up slowly.
In fact, I forgot to mention: Do not post Olympiad problems.
In that case you post a problem for me because I am leaving in like 5 minutes and not going to be here for a day. So that will delay this thread unless you want to wait.
This is an IMO problem. You are right, it is not right to post such hard problems.In fact, I forgot to mention: Do not post Olympiad problems.
