Verify that multiplying a matrix by its inverse results in 1. Use matrix multiplication to find the inverse of a matrix. Find an inverse by augmenting with an identity matrix.We know that the multiplicative inverse of a real number aa is a−1a−1 and aa−1=a−1a=(1a)a=1aa−...
The inverse of a matrix is the matrix that, when multiplied by the original matrix, gives rise to the identity matrix. The identity matrix has zeros in all positions except for its diagonal, which consists of all ones. Answer and Explanation: To solve for this 2x2 matrix, we need to ...
