Image: Approximating region as parallelogram to calculate area under transformationThe change of variables function $\cvarf$ transforms a small rectangle in the $\cvarfv\cvarsv$ plane to a “curvy rectangle” in the $xy$ plane. We approximate the area of the “curvy rectangle” by using a parallelogram.
