Geometric vs analytical jacobian
WebAnswer (1 of 3): That you call "regular geometry" is synthetic geometry. The approach in synthetic geometry is to go from the axioms, postulates and definitions to the thing that … WebGreat question! It means that the orientation of the little area has been reversed. For example, if you travel around a little square in the clockwise direction in the parameter space, and the Jacobian Determinant in that region is negative, then the path in the output space will be a little parallelogram traversed counterclockwise.Another way to think about …
