Transcribed Image Text:### Problem 2: Find the Volume
#### Diagram Explanation
The diagram represents a 3D plot with the function \( z = \cos x \cos y \). The surface is shown over a specific region, bounded by the x, y, and z axes. Key points on the axes are labeled as follows:
- On the x-axis, the interval is from \(-\frac{\pi}{4}\) to \(\frac{\pi}{4}\).
- On the y-axis, the region is defined in the same interval as the x-axis: \(-\frac{\pi}{4}\) to \(\frac{\pi}{4}\).
- The function creates a surface above this rectangular base in the xy-plane.
The surface is shaped like a smooth wave bending upwards towards the center of the plot, due to the cosine functions.
This problem involves calculating the volume under the surface \( z = \cos x \cos y \) and above the rectangular region defined in the xy-plane.
