Question
![**Problem Statement:**
Use the transformation \( x = u^2 - v^2, \, y = 2uv \) to evaluate the integral
\[
\int_0^1 \int_0^{2\sqrt{1-x}} \sqrt{x^2 + y^2} \, dy \, dx.
\]
**Instructions:**
- Given the transformation, apply it to simplify and evaluate the given integral.
- Consider the limits of integration in terms of the new variables \( u \) and \( v \).
- Evaluate the transformed integral step-by-step.
**Notes:**
- Verify the transformation by looking at the Jacobian determinant.
- Carefully work through algebraic manipulations and integration techniques.
- Interpret any geometric significance of the transformation if applicable.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fbe7e575d-dfd7-411c-ad5f-62e2be64ba9f%2F8ba2092e-9460-4209-ac76-cd542b380bd0%2Fjguqsyn_processed.jpeg&w=3840&q=75)
