Hey guys! i recently joined a new site for iit and olympiads and i saw a good sum there! anyone wants to try it? :)
 
Let
\alpha = tan^{-1} \frac {4}{3}.
Prove that there exists n \in \mathbb{N} such that

0 < \sin {n\alpha} < \frac {1}{2008} :s
 
I'll tell you the site for you people's benefit, its just started but it has some good problems :)

@ananth_patri ....
our attempt isn't to compete with anyone it's just a step forward from our part to spread the little knowledge that we have...
as is the aim of GoIIT
we are here to support not to compete

Thanks

 I TRIED BY INDUCTION BUT I DID NOT GET P(1) TO BO TRUE .
 
sin(tan-1(4/3)) = sin(sin-1(4/5)) = 4/5 now is 4/5 < 1/2008 .
 
WHAT IS WRONG.
