WebR1 If two rows are swapped, the determinant of the matrix is negated. (Theorem 4.) R2 If one row is multiplied by ﬁ, then the determinant is multiplied by ﬁ. (Theorem 1.) R3 If a multiple of a row is added to another row, the determinant is unchanged. (Corollary 6.) R4 If there is a row of all zeros, or if two rows are equal, then the ... WebAs in the one-dimensional case, the geometric properties of this mapping will be reflected in the determinant of the matrix A associated with T. To begin, we look at the linear transformation. T ( x, y) = [ − 2 0 0 − 2] [ x y]. As with all linear transformations, it maps the origin x = ( 0, 0) back to the origin ( 0, 0).
