more. What Sal introduced here in this video, is a method that was 'woven' specially for finding inverse of a 2x2 matrix but it comes from a more general formula for determining inverse of any nxn matrix A which is: A⁻¹ = 1/det (A) * adj (A) where adj (A) - adjugate of A - is just the transpose of cofactor matrix Cᵀ. The inverse of A is A-1 only when A × A-1 = A-1 × A = I. To find the inverse of a 2x2 matrix: swap the positions of a and d, put negatives in front of b and c, and divide everything by the determinant (ad-bc). Sometimes there is no inverse at all. 2x2 Inverse Matrix Calculator to find the inverse of 2x2 matrix. 2x2 Matrix has two rows and two columns. Matrix Inverse is denoted by A-1. The Inverse matrix is also called as a invertible or nonsingular matrix.
