Finding the determinant 2x2
WebDeterminant of a 2 x 2 Matrix Suppose, A = [aij] is a 2 x 2 matrix (order two matrix), such that; A = [ a b c d] Then the determinant of A is defined as: Det (A) = A = a 11 a 12 a 21 a 22 Det (A) = a 11 .a 22 – a 12 .a 21 Or A = a 11 .a 22 – a 12 .a 21 This is the determinant formula for matrix of order two. Determinant Related Articles WebWe can either use that formula or simply the following steps instead of the formula to find the inverse of 2x2 matrix. The steps are explained with an example where we are going to find the inverse of A = ⎡ ⎢⎣1 −1 0 2⎤ ⎥⎦ [ 1 − 1 0 2]. Step - 1: Find the det A just by cross multiplying the elements and subtracting.
