WebFind the inverse of 2x2 matrix X X defined below: Equation 17: Matrix X For this, as mentioned before, we use equation 5 (inverse of 2x2 matrix formula) assuming the matrix X follows the element notation from equation 3. Therefore, the computation of the 2x2 inverse matrix goes as follows: Equation 18: Matrix inverse of X Example 5 WebAbout the method To calculate inverse matrix you need to do the following steps. Set the matrix (must be square) and append the identity matrix of the same dimension to it. Reduce the left matrix to row echelon form using elementary row operations for the whole matrix (including the right one). Webwhere I is the 2× 2 identity matrix 1 0 0 1!. That is, multiplying a matrix by its inverse produces an identity matrix. Note that in this context A−1 does not mean 1 A. Not all 2× 2 matrices have an inverse matrix. If the determinant of the matrix is zero, then it will not have an inverse; the matrix is then said to be singular. profile summary for freshers bpo
