Web8 apr. 2012 · We know that inverse of matrix is calculated using formula: Multiplying this equation by A, we can write as and and From above, we can say that det (A)I=A.adj (A) and det (A)I=adj (A).A From above equations, we can say that A.adj (A)=adj (A).A=det (A)I which is the desired result.
If A is a square matrix of order n, then adj (adj A ) is equal to - Toppr
WebExample 1: If A T = – A then the elements on the diagonal of the matrix are equal to (a) 1 (b) -1 (c) 0 (d) none of these Solution: 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 WebWe have, A = 01- 1213321 = 0 + 7 - 1 = 6∴ AadjAA- 1A = AadjA A- 1A = AII = AI2 = AI = 6I = 600060006 = 2300030003 interpedia clinic milwaukee
