WebExample: Step 1: Find the determinant. Step 2: Swap the elements of the leading diagonal. Recall: The leading diagonal is from top left to bottom right of the matrix. Step 3: Change the signs of the elements of the other diagonal. Step 4: Divide each element by the determinant. When a matrix has no inverse it is called a singular matrix. WebStep 1: Choose any row or column. We usually choose the first row to find the determinant. Step 2: Find the co-factors of each of the elements of the row/column that we have chosen in Step 1. Step 3: Multiply the elements of the row/column from Step 1 with the corresponding co-factors obtained from Step 2.

"WebIf 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 " - How to solve 2*2 matrix
