Find a set on which the sequence $\sin\left(\left(1+\frac1{n}\right)^x\right)$ converge pointwise. Thanks for any help.

I think we are required to find for which values of $x$ does the sequence converge pointwise!

    Try showing us where you got stuck, this way you learn way more then that we just give you the answer.2012-01-07

    Notice that sin is continuous everywhere; so if $\left( 1 + \frac1n \right)^x$ converges, then the given sequence also would converge. Does this hint help?2012-01-07
