### Newton-Raphson Method and Newton's Divided Difference Interpolation

#### 2. Solve by Newton Raphson method. (5 iterations)

Given the equation:
\[ 
x + \ln x = 2, \quad x_0 = 2 
\]

Use the Newton-Raphson method to find the solution with 5 iterations.

#### 3. Using Excel and Newton’s Divided Difference Interpolation compute \( f(5.1) \)

Consider the following table of values:

\[
\begin{array}{|c|c|}
\hline
x_j & f_j \equiv f(x_j) \\
\hline
4.0 & 89 \\
\hline
5.0 & 253 \\
\hline
6.0 & 741 \\
\hline
7.0 & 2201 \\
\hline
\end{array}
\]

Use Excel and Newton's Divided Difference Interpolation method to compute \( f(5.1) \).

### Explanation:

1. **Newton-Raphson Method Steps**:
    - **Iteration Process**:
      - Step 1: Start with the initial guess \( x_0 = 2 \)
      - Step 2: Use the formula \( x_{n+1} = x_n - \frac{f(x_n)}{f'(x_n)} \)
      - Step 3: Calculate for 5 iterations.

2. **Newton's Divided Difference Interpolation Steps**:
    - **Piecewise Polynomial**: Construct a polynomial using the given data points.
    - **Divided Differences Table**:
        - Create a table to calculate the interpolation polynomial's coefficients.
    - **Evaluate Polynomial**:
        - Substitute \( x = 5.1 \) into the polynomial to find \( f(5.1) \).

This method is beneficial when the function isn't straightforward, and numerical methods are required to find an accurate solution.
