Double Integral with a Given Substitution

Multiple integrals core

Using the substitutions $x = v$ and $y = \sqrt{u + v}$, evaluate the integral $\iint_{R} y \sin(y^2 - x) \, dA$ where $R$ is the region bounded by the lines $y = \sqrt{x}$, $x = 2$, and $y = 0$.

What this problem tests

Tests the ability to compute a Jacobian, map boundaries to a new coordinate system, and evaluate the resulting iterated integral.

This is a standard problem in a multivariable calculus course covering multiple integration and coordinate transformations.
