![### Educational Content: Calculating a Double Integral
**Problem Statement:**
Calculate the double integral:
\[
\iint_R x \sec^2(y) \, dA
\]
where the region \( R \) is defined by:
\[
R = \{ (x, y) \mid 0 \leq x \leq 6, \, 0 \leq y \leq \frac{\pi}{4} \}
\]
**Details:**
- **Double Integral:** The problem involves calculating a double integral over a rectangular region \( R \) in the xy-plane.
- **Function to Integrate:** The function given is \( x \sec^2(y) \).
- **Region \( R \):** The limits of integration for \( x \) are from 0 to 6, and for \( y \) are from 0 to \( \frac{\pi}{4} \).
**Explanation:**
1. **Integration with respect to \( y \):** Since the integrand can be separated as \( x \times \sec^2(y) \), you would likely integrate with respect to \( y \) first within its bounds, treating \( x \) as a constant.
2. **Integration with respect to \( x \):** After integrating with respect to \( y \), the resulting expression is then integrated with respect to \( x \) from 0 to 6.
This problem is a typical exercise in evaluating double integrals, often found in calculus courses, and encourages an understanding of integrating over a defined planar region.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F763773a4-b59e-428b-8a3f-bc3dd5fb97d6%2F0316f031-f527-4c36-9505-dadf966c8337%2Fe8vnqfv_processed.png&w=3840&q=75)
