Inverse matrix can be calculated using different methods. Learn what is inverse matrix, how to find the inverse matrix for 2x2 and 3x3 matrices along with the steps and solved examples here at BYJU'S.
If a square matrix \(A\) has an inverse, then the determinant of an inverse matrix is the reciprocal of the matrix determinant. i.e., \(\left| {{A^{ – 1}}} \right| = \frac{1}{{|A|}}\). If a square matrix \(A\) has an inverse, for a scalar \(k \ne 0\) then t...
