The Jacobian determinant is a scalar value that represents the rate of transformation of volume when changing from one coordinate system to another in multiple dimensions. It is calculated as the determinant of the Jacobian matrix, which consists of all first-order partial derivatives of a vector-valued function. This determinant plays a crucial role in multidimensional integration by helping to adjust the volume elements when integrating over transformed regions.
