Determinant of adjugate matrix
Did you know?
The adjugate of A is the transpose of the cofactor matrix C of A, In more detail, suppose R is a unital commutative ring and A is an n × n matrix with entries from R. The (i, j)-minor of A, denoted Mij, is the determinant of the (n − 1) × (n − 1) matrix that results from deleting row i and column j of A. The cofactor matrix of A is the n × n matrix C whose (i, j) entry is the (i, j) cofactor of A, which is the (i, j)-minor times a sign factor: WebThe matrix on the right is a diagonal matrix with each diagonal entry equal to $detA$ Thus, its determinant will simply be the product of the diagonal entries, $(\det A)^n$ Also, using the multiplicity of determinant function, we get $\det(A\cdot adjA) = \det A\cdot …
