Question
![**Title: Finding the Area Inside Intersecting Cardioids Using Double Integrals**
**Introduction**
This exercise focuses on using a double integral to find the area of a region enclosed by two cardioids, represented by the polar equations \( r = 1 + \sin \theta \) and \( r = 1 + \cos \theta \).
**Instructions**
We will set up a double integral in polar coordinates to determine the area inside \( r = 1 + \cos \theta \) until it intersects with \( r = 1 + \sin \theta \). By leveraging symmetry, the area of the region can be calculated and then doubled for a complete solution.
**Double Integral Setup**
The expression to solve:
\[
\int \int r \, dr \, d\theta
\]
**Diagram Explanation**
The exercise provides integral symbols with blank spaces to indicate where limits of integration should be placed. These limits will depend on the points of intersection and the symmetry properties of the cardioids.
**Key Considerations**
- Determine points of intersection between the two cardioids.
- Use the symmetry of the cardioids to set and evaluate the integral efficiently.
- After setting up and calculating the integral for half of the region, double the result to find the total area.
This method ensures that the area calculation is both precise and efficient by fully utilizing the inherent properties of the cardioids.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa75075be-9707-4a74-aab1-9b0f0fa2cd8d%2Fe7a032b9-c984-41dd-8ee7-64e7f76ea451%2F41xqevc_processed.png&w=3840&q=75)
