### Understanding the Riemann Zeta Function

The Riemann zeta function, denoted as ζ(s), is defined by the following infinite series:

\[ \zeta(s) = \sum_{n=1}^{\infty} \frac{1}{n^s} \]

where \( s \) is a complex number with a real part greater than 1.

### Exploration Task

1. **The Basel Problem Connection:**
   - Evaluate the Riemann zeta function at \( s = 2 \), i.e., find \( \zeta(2) \). This evaluation is known to align with the solution to the Basel Problem.

2. **Existence for \( s > 1 \):**
   - Demonstrate that the Riemann zeta function \( \zeta(s) \) exists and is well-defined for all \( s \) with a real part greater than 1.

#### Key Points

- **Basel Problem:** Historically, the Basel Problem refers to the challenge of finding the exact sum of the reciprocals of the squares of the natural numbers. Mathematically, this is expressed as:
  
  \[ \sum_{n=1}^{\infty} \frac{1}{n^2} \]
  
  The solution to the Basel Problem is known, and evaluating \( \zeta(2) \) provides the exact value.

- **Convergence of Series:**
  - For \( s \) with a real part greater than 1, the series converges, meaning the sum approaches a specific finite value. This property ensures that \( \zeta(s) \) is defined and exists for these values of \( s \).

---

This content should assist learners in understanding the practical application of the Riemann zeta function in relation to the Basel Problem and the conditions under which the series converges.
