Step-by-step explanation:

The adjoint of a matrix (also called the adjugate of a matrix) is defined as the transpose of the cofactor matrix of that particular matrix. For a matrix A, the adjoint is denoted as adj (A). On the other hand, the inverse of a matrix A is that matrix which when multiplied by the matrix A give an identity matrix.

Answer:

Example 1 :- How to find adjoint of a matrix?

Question:- If A^T = - A then the elements of the diagonal of the matrix are equal to

(a) 1. (b)-1. (c) 0 (d) none of these

Answer- (c) 0

Step-by-step explanation:

A^T=- A; A is a skew symmetric matrix; diagonal elements of A are zero's.

So option (c) will be the answer.
