**Problem: Polar Curves and Tangents**

**Task:** Sketch the polar curve \( r^2 = \cos(6\theta) \) and compute the tangent line at the value \( \theta = \frac{\pi}{24} \).

**Instructions:**
1. Begin by understanding the polar equation \( r^2 = \cos(6\theta) \).
   - This equation expresses a relationship between the radius \( r \) and the angle \( \theta \) in polar coordinates.
   - It involves a cosine term with a multiple angle, which suggests the curve will have multiple symmetries or petals.

2. To sketch the curve:
   - Evaluate \( r \) for several values of \( \theta \) ranging from 0 to \( 2\pi \).
   - Note when \( \cos(6\theta) \) results in positive, zero, and negative values to determine where the curve crosses the pole (origin) and where it is undefined.

3. To find the tangent line at \( \theta = \frac{\pi}{24} \):
   - Calculate the derivative of \( r \) with respect to \( \theta \) to find the slope of the tangent.
   - Use the relationship \( \frac{dr}{d\theta} \) and evaluate it at \( \theta = \frac{\pi}{24} \).

4. Consider converting to Cartesian coordinates if necessary for finding the equation of the tangent line:
   - Use the transformation \( x = r\cos(\theta) \) and \( y = r\sin(\theta) \).

5. Analyze graphically:
   - Diagrams may illustrate how the curve behaves and where the tangent line is located for better visualization.

By understanding these steps, you can accurately sketch and analyze the polar curve and compute the required tangent line.
