The multiplicative inverse of a matrix gives the identity matrix when a matrix is multiplied with its inverse matrix. For a square matrixA, the multiplicative inverse is given by,AA−1=I=A−1A. How do you find the multiplicative inverse of a 2x2 matrix?
What is the formula for the inverse matrix? Using the adjoint formula, we find that the formula for the inverse of a matrix \(A\) is: \[ A^{-1} = \displaystyle \frac{1}{\det(A)} adj(A)\] At first sight this looks simple! But it is not so much when the size of the matr...
