Math Problem Statement
Solution
The problem asks us to:
- Sketch the region of integration.
- Reverse the order of integration.
- Evaluate the integral.
Given the double integral:
Let's go through these steps:
1. Sketching the Region of Integration
The integral has the outer limits for from to , and the inner limits for from to .
The bounds describe the region:
- ranges from to .
- ranges from to .
The curve defines the lower boundary for , and the line is the upper boundary.
2. Reversing the Order of Integration
To reverse the order of integration, we need to describe in terms of .
- From , we get .
- ranges from to , and ranges from to .
The region can be rewritten with ranging from to and ranging from to . Thus, the reversed integral becomes:
3. Evaluating the Integral
Now, let's evaluate the reversed integral:
Therefore, the value of the integral is:
