<p>Draw the curves <i>p</i>|cos θ| and <i>q</i>|sin θ| and find the number of intersection points.</p>
Step-by-Step Solution
Key Concept: Graphical analysis of absolute value trigonometric functions to find intersection points.
<p><strong>Solution:</strong> By analyzing the graphs of <i>p</i>|cos θ| and <i>q</i>|sin θ|, we identify the intersection points labeled A, B, C, D in the diagram.</p><p>∴ Number of solutions is 4.</p>
Correct Answer: 4
