WebSolution: A T = -A; A is skew-symmetric matrix; diagonal elements of A are zeros. so option (c) is the answer. Example 2: If A and B are two skew-symmetric matrices of order n, then, (a) AB is a skew-symmetric matrix. (b) AB is a symmetric matrix. (c) AB is a symmetric matrix if A and B commute. (d) None of these. WebIn this page adjoint of a matrix we are going to some examples to find ad-joint of any matrix. Definition: Let A = [aij] be a square matrix of order n. Let Aij be a cofactor of aij. Then nth order matrix [Aij]^T is called adjoint of A. It is denoted by Adj A. In other words we can define adjoint of matrix as transpose of co factor 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… http://math.stanford.edu/~akshay/math113/11.12.pdf naming file conventions
