Question
**Educational Content on Sequences and the Squeeze Theorem**

---

**Exercise 32:**
- **Objective:** Show that the sum of a certain sequence is a divergent sequence.
- **Concepts Explored:** Divergence of sequences, analysis of series.

**Explore what you can derive about divergent sequences through this exercise. Dive into methods that help determine the behavior of sequences over an infinite range.**

---

**Exercise 33:**
- **Objective:** Use the Squeeze Theorem to prove that each of the following sequences converges.

   a) \(\{ \sin n/n \}\)

   b) \(\{ n^3/2^n \}\)

   c) \(\{ 3^n/n! \}\)

- **Concepts Explored:** The Squeeze Theorem is a powerful tool in calculus used to prove the convergence of sequences by comparing them to two other sequences that 'squeeze' the given sequence.

**Approach the task by setting bounds on the sequences and using the theorem to infer their limits as \( n \rightarrow \infty \).**

---

**Further Explanation:**
- **Squeeze Theorem:** If you have a sequence \(\{a_n\}\) such that \(a_n \leq b_n \leq c_n\) for all \(n\), and if \(\lim_{n \to \infty} a_n = \lim_{n \to \infty} c_n = L\), then \(\lim_{n \to \infty} b_n = L\).

**Engage with these exercises to strengthen your understanding of sequence convergence through practical application of the Squeeze Theorem.**
