### Polar to Cartesian Coordinates Conversion

This educational material focuses on converting polar coordinates to Cartesian coordinates, complete with visual graph representations.

#### Question (b)
**Given Polar Coordinates:**
\[ \left( 3\sqrt{2}, \frac{\pi}{4} \right) \]

You are provided with four graphs labeled as Choice A, B, C, and D, each displaying a Cartesian plane with a plotted point. Your task is to identify which graph correctly represents the Cartesian conversion of the given polar coordinates.

The graphs have the following properties:

- Each graph contains x and y axes ranging from -4 to 4.
- A specific point is plotted in each graph indicating its (x, y) position.

**Explanation of the Graphs:**

1. **Choice A:**
   - The point is plotted at approximately \((-2, -2)\).

2. **Choice B:**
   - The point is plotted at approximately \((3, 0)\).

3. **Choice C:**
   - The point is plotted at approximately \((2, 2)\).

4. **Choice D:**
   - The point is plotted at approximately \((0, 3)\).

**Conversion Formula:**

To convert from polar (\(r, \theta\)) to Cartesian (\(x, y\)) coordinates:
- \(x = r \cdot \cos(\theta)\)
- \(y = r \cdot \sin(\theta)\)

Applying the conversion:
- \(r = 3\sqrt{2}\)
- \(\theta = \frac{\pi}{4}\)

Calculate:
- \(x = 3\sqrt{2} \cdot \cos\left(\frac{\pi}{4}\right) = 3\sqrt{2} \cdot \frac{\sqrt{2}}{2} = 3\)
- \(y = 3\sqrt{2} \cdot \sin\left(\frac{\pi}{4}\right) = 3\sqrt{2} \cdot \frac{\sqrt{2}}{2} = 3\)

Thus, the correct Cartesian coordinates are \((3, 3)\).

Using this information, select the correct graph.

**Title: Conversion of Polar Coordinates to Cartesian Coordinates**

**Objective:**
Plot the point defined by polar coordinates and find its Cartesian coordinates.

**Problem Statement:**
Given polar coordinates \( (3, \frac{3\pi}{2}) \), plot the point and determine its Cartesian coordinates.

**Graphical Representation:**
Four options labeled as Choice A, B, C, and D are provided, each with a distinct point plotted on a Cartesian coordinate system.

1. **Choice A:** Point is at \((-3, 0)\).
2. **Choice B:** Point is at \((0, -3)\).
3. **Choice C:** Point is at \((0, 3)\).
4. **Choice D:** Point is at \((3, 0)\).

**Conversion Formula:**
To convert from polar coordinates \((r, \theta)\) to Cartesian coordinates \((x, y)\):
- \( x = r \cos \theta \)
- \( y = r \sin \theta \)

**Solution Steps:**

1. **Calculate Cartesian Coordinates:**
   - Given: \( r = 3 \), \( \theta = \frac{3\pi}{2} \)
   - \( x = 3 \cos \frac{3\pi}{2} = 3 \times 0 = 0 \)
   - \( y = 3 \sin \frac{3\pi}{2} = 3 \times (-1) = -3 \)

2. **Identify Correct Choice:**
   - The correct Cartesian coordinates are \( (0, -3) \), which corresponds to Choice B.

**Final Answer:**
\( (x, y) = (0, -3) \)

This exercise aids in understanding the relationship between polar and Cartesian coordinate systems by practicing conversions and plotting points accurately.
