**Problem 5: Polar Graph Sketching**
Sketch the graph of \( r = 2 \cos 3\theta \) over \([0, \pi]\). Use \( x \) on \([-3, 3]\) and \( y \) on \([-3, 3]\) when using your graphing calculator.
**Graph/Diagram Explanation**
The image features a blank graph with a set of coordinate axes. The horizontal axis extends from left to right, and the vertical axis extends from bottom to top, both with arrows indicating direction. This coordinate plane will be used to plot the polar equation \( r = 2 \cos 3\theta \) within the specified bounds.
**Instructions:**
1. **Graphing the Equation**:
- This polar equation should be graphed within the specified range for \(\theta\) and \(r\).
- Make sure your graphing calculator is set to polar mode to input the equation and range correctly.
2. **Axes Limits**:
- The x-axis should range from -3 to 3.
- The y-axis should also range from -3 to 3.
3. **Expected Graph Shape**:
- The equation \( r = 2 \cos 3\theta \) represents a rose curve.
- For each complete rotation of \(\theta\) from 0 to \(\pi\), the graph should exhibit symmetric petal-like structures.
By setting these parameters and using your graphing calculator, you should be able to visualize the rose curve pattern represented by the given polar equation.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6f6fed45-037c-4b7d-8be3-2fd31594defe%2F4f796912-e805-4160-adda-730b0d54517a%2F3fzxold_processed.jpeg&w=3840&q=75)
