WebApr 14, 2024 · The determinant (not to be confused with an absolute value!) is , the signed length of the segment. In 2-D, look at the matrix as two 2-dimensional points on the plane, and complete the parallelogram that includes those two points and the origin. The (signed) area of this parallelogram is the determinant.
