I need help figuring out this problem. Thanks!
![The image presents a mathematical problem involving integration over a specific region \( R \). The details are as follows:
**Definition of Region \( R \):**
Region \( R \) is defined as a set of points \((x, y)\) such that:
- \( 1 \leq x^2 + y^2 \leq 4 \)
- \( 0 \leq y \leq x \)
This describes an annular sector between the circles \( x^2 + y^2 = 1 \) and \( x^2 + y^2 = 4 \) in the first quadrant, bounded by the line \( y = x \).
**Diagram Explanation:**
The diagram presents two concentric circles centered at the origin:
- The inner circle has a radius of 1.
- The outer circle has a radius of 2.
Both are intersected by the line \( y = x \), and the region is shaded where the conditions are satisfied. This region is a sector of the annular area formed by the two circles between the angles:
- \( 0 \leq \theta \leq \pi/4 \)
**Integration Problem:**
The integral to be evaluated over the region \( R \) is:
\[
\iint_R \tan^{-1}\left(\frac{y}{x}\right) \, dA
\]
This involves integrating the function \(\tan^{-1}\left(\frac{y}{x}\right)\) over the specified region \( R \).
The limits for the polar coordinates representation of the region are:
- Radial distance: \( 1 \leq r \leq 2 \)
- Angle: \( 0 \leq \theta \leq \pi/4 \)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8c896c9e-cf63-433a-88d4-0dfcdf4ef2b0%2F53c24b64-292e-46bc-8267-590d56e7bb1f%2Fnigdh8_processed.jpeg&w=3840&q=75)
