I think the argument is that you can find large n such that sin(n) is close to 1. Then 1/n is close to 0 so the upper limit in question tends to 1 because N1 ^ N2 tends to 1 if N1 tends to 1 and N2 tends to 0.
So I'd agree with Timothy Murphy about the clarity of the upper limit being 1. I think you may be thinking of sin(n) ^ n. This is a case where the proof of whatever the upper limit is would be much deeper than the above.
