I am wondering how to get started on writing the proof to
|sin nx| <= |sin x| for all x in R and P.

Shark, I could give you a generic description how induction, but so could mathworld.
If you want specific help on getting started with this problem, you'll need to finish describing the problem! You have not defined the sets R and P, and we don't know what values "n" can be!
I assume it is supposed to be abs(sin(n*x)) <= abs(sin(x))

I don't think you wrote this correctly. The sin of .2 is greater than the sin of .1 for example, so if n=2 this isn't always correct if N is in the set of integers.
