How to take the adjoint of a matrix

In linear algebra, the adjugate or classical adjoint of a square matrix A is the transpose of its cofactor matrix and is denoted by adj(A). It is also occasionally known as adjunct matrix, or "adjoint", though the latter term today normally refers to a different concept, the adjoint operator which for a matrix is the conjugate transpose. The product of a matrix with its adjugate gives a diagonal matrix (entries not on the main diagona… WebI thought that that isn't much of a trick or shortcut; it seems about the same complexity as just plodding through row/column operations to convert the 3x3 into an identity matrix and applying those operations to an identity matrix at the same time. Of course, if there's an expectation that the determinant is 1, then maybe it's appropriate.

The adjugate of an invertible matrix m is given by Inverse [m] Det [m]. The matrix product of a matrix m with its adjugate is equal to the determinant of m multiplied by an identity matrix of the same size as m. The matrix m can be numerical or symbolic, but must be square.

What Sal introduced here in this video, is a method that was 'woven' specially for finding inverse of a 2x2 matrix but it comes from a more general formula for determining inverse of any nxn matrix A which is: A⁻¹ = 1/det (A) * adj (A) where adj (A) - adjugate of A - is just the transpose of cofactor matrix Cᵀ.

WebThis was a good algebraic derivation of the adjoint. At least I'm seeing how the adjoint is existing, albeit somewhat indirectly. We do know what the inverse does, so we can define adjoint to be adj(A) = A^(-1)*det(A). The next step would be to show that this definition is equivalent to the cofactor definition of the adjoint. WebNow, as isn't invertible, this implies , thus completing the proof. [Case II] det (Adj (A)) = nonzero, so Adj (A) is invertible. Let (Adj (A))^ {-1} =B. From A Adj (A)=det (A)I, A Adj (A) B= det (A)I B. Suppose that det (A)=0. Then A = 0. So Adj A =0 implies det (Adj A)=0, a contradiction. Therefore det (A) = nonzero.
