Inverse of a 2x2 Matrix - ChiliMath
www.chilimath.com › inverse-of-a-2x2-matrixIf a 2×2 matrix A is invertible and is multiplied by its inverse (denoted by the symbol A−1 ), the resulting product is the Identity matrix which is denoted by I I. To illustrate this concept, see the diagram below. In fact, I can switch the order or direction of multiplication between matrices A and A −1, and I would still get the Identity matrix
