Evaluation of determinants of 2nd and 3rd Order Matrices
Definition: Every square matrix can be associated to an expression or a number which is known as its determinant. If A = [aij] is a square matrix of order n then the determinant of A is denoted by or |A| or . Determinant of a square matrix of order 1: If A = [a11] is a Read more about Evaluation of determinants of 2nd and 3rd Order Matrices[…]
