![### Calculating the Area Enclosed by Given Curves
In this lesson, we will learn how to find the area enclosed by two curves, specifically focusing on the following curves:
\[ y = 3 \sin \left( \frac{\pi x}{7} \right), \quad y = \frac{6}{7} x \]
### Graphical Approach to Finding the Enclosed Area
#### Steps to solve the problem:
1. **Graph the Functions:**
- Plot the curves given by the equations \( y = 3 \sin \left( \frac{\pi x}{7} \right) \) and \( y = \frac{6}{7} x \) on the same coordinate axes.
2. **Identify the Region to Integrate:**
- Identify the region enclosed by the two curves. This region will be shaded on the graph.
3. **Choose the Axis of Integration:**
- Decide whether to integrate with respect to \( x \) or \( y \). This decision is based on which method simplifies the calculation.
4. **Draw an Approximating Rectangle:**
- Draw a typical approximating rectangle to visualize the process of integration.
#### Graphs and Explanations:
- **Top Left Graph:**
- The graph plots the curves \( y = 3 \sin \left( \frac{\pi x}{7} \right) \) and \( y = \frac{6}{7} x \) with the shaded region indicating the enclosed area.
- A vertical red rectangle (typical approximating rectangle) is drawn in the first quadrant within the enclosed region. This rectangle represents a small segment used for integration.
- **Top Right Graph:**
- Similar to the top left graph but with a different placement of the typical approximating rectangle, shown in the fourth quadrant.
- **Bottom Left Graph:**
- This graph shows the curves with the enclosed area shaded. The red rectangle is drawn horizontally, showing an integration approach with respect to \( y \).
- **Bottom Right Graph:**
- The correct integration approach is depicted with the red rectangle in the first quadrant, fitting between the two curves.
### Correct Solution Identification:
- The correct graph for solving this problem is the **bottom right graph**. It depicts the integration with respect to \( y \), as denoted by the green check mark.
