WebWhen A is equal to A transpose? If A−1=AT, then ATA=I. This means that each column has unit length and is perpendicular to every other column. That means it is an orthonormal … WebA real square matrix whose inverse is equal to its transpose is called an orthogonal matrix. A T = A-1. For an orthogonal matrix, the product of the matrix and its transpose are equal to an identity matrix. AA T = A T A = I. The determinant of an orthogonal matrix is +1 or -1. All orthogonal matrices are symmetric and invertible. WebThe transpose is then . A T = E 1 T... E k T. Since an elementary matrix and its transpose are easily seen to have the same determinant, the result det A T = det A follows in this case from repeated application of (b). On the other hand, if A is not invertible, then neither is its transpose, so in this case both detA and detA T are zero by part ... how does repayment work on a heloc
