![### Lecture 3.2: Estimating √3 Using the Bisection Method (Up to 3 Iterations)
---
#### Objective:
Estimate \(\sqrt{3}\) (root 3) using the Bisection Method, up to 3 iterations.
Given:
- \(\sqrt{3} \approx x_3\)
- Using \( a = 1 \) and \( b = 2 \)
#### Theory (Intermediate Value Theorem):
**Intermediate Value Theorem (IVT):**
Let \( f(x) \) be continuous on the interval \([a, b]\), and assume that \( f(a) \cdot f(b) < 0 \). Then, there exists a number \( c \) in the interval \((a, b)\) such that \( f(c) = 0 \).
In mathematical notation:
\[ \exists c \in (a, b) \ \text{such that} \ f(c) = 0 \]
where \( c \) is a root for \( f(x) \).
---
#### Steps:
1. **Choose Initial Interval:**
- Initial interval is chosen as \([1, 2]\).
2. **Apply the Bisection Method:**
- Use the properties of the function’s continuity and the Intermediate Value Theorem to iteratively narrow down the interval to identify the root.
3. **Iterations:**
- Perform the bisection method for up to 3 iterations to estimate \(\sqrt{3}\).
---
By leveraging the above principles and steps, one can estimate \(\sqrt{3}\) effectively using the bisection method. Each iteration will successively narrow the interval where the root lies, thus improving the accuracy of the estimate.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc58b2eee-5b79-4c9d-923b-d4e913d44dbe%2F92415563-5c23-450e-9d72-3c55bb4f2b39%2Fkq9iq3m_processed.png&w=3840&q=75)
