**Problem 0.1**

Determine whether the following sequences converge as \( n \to \infty \):

1. \( a_n = \frac{n^3}{3^n} \)

2. \( a_n = \frac{n!}{e^n} \)

3. \( a_n = \frac{n^n}{n!} \)

For (3), you may use the following identity:

\[
\lim_{n \to \infty} \left(1 + \frac{1}{n}\right)^n = e \approx 2.718 \ (> 1).
\]
