Webdeterminant: [noun] an element that identifies or determines the nature of something or that fixes or conditions an outcome. WebThe naive definition of volume is always positive whereas the determinant could be negative, so there is some explaining to do in terms of orientations. The route most often chosen both by instructors and textbook writers is the algebraic one where one can write down a magic formula and, boom! the determinant has been defined.
