Web1. A determinant is linear in the elements of any row (or column) so that multiplying everything in that row by z multiplies the determinant by z, and the determinant with row v + w is the sum of the determinants otherwise identical with that row being v and that row being w. 2. It changes sign if two of its rows are interchanged ( an ... WebSo then the determinant is not always the area of a parallelogram? Here is the main take away.
