I have been strugling a lot to solve this question, but couldn't figure out where to start.

$$ \lim_{x \to \infty } \sqrt{n} . \underbrace {\sin(\sin(\sin ... (\sin (1))...))}_{n...times..} $$

I think maybe I should assume the part inside brackets as $y$.

But what next??

Any hints/suggestions?

  • $\begingroup$ Presumably $x$ and $n$ are somehow related... $\endgroup$

    $\begingroup$ It should be $n \to +\infty $ instead of $x \to +\infty $, no? $\endgroup$

  • $\begingroup$ @IvoTerek yes, sorry. $\endgroup$ Jan 3, 2015 at 15:24
  • $\begingroup$ @math110 I saw that link but didn't understand the solution as it involves range, domain etc. and more concerned with analysis. Can I xpect a bit easier solution? something more basic? $\endgroup$ Jan 3, 2015 at 15:26
