Answer

converges to 0

Work Step by Step

To determine if the sequence converges, determine if the limit at n approaches infinity exists. $=\lim\limits_{n \to \infty} \frac {sin(n)}{n}$ Utilizing the "sandwich theorem", the limit as n approaches infinity of both $\frac {1}{n}$ and $-\frac {1}{n}$ are zero, so the limit as $\frac {sin(n)}{n}$ approaches zero is zero. Therefore, the sequence converges to 0.
