(1 point) Consider the series $\sum_{n=1}^{\infty} a_n$ where $a_n = \sin^n(\frac{6}{\sqrt{n}})$. Compute the limit: $\lim_{n \to \infty} \sqrt[n]{a_n} = 6$ (Enter \"infinity\" or \"inf\" if the limit is infinity, enter \"DNE\" if the limit does not exist for another reason.) Given your answer above, what does the root test tell you about the series? The root test tells us that the series converges,
