Inverse matrix
Row-reduce the matrix until the left side to the Identity matrix. When the left side is the Identity matrix, the right side will be the Inverse [ I | A-1]. If you are unable to obtain the identity matrix on the left side, then the matrix is singular and has no inverse. Take the

inverse of a matrix: definition

Well, for a 2×2 matrix the inverse is: In other words: swap the positions of a and d, put negatives in front of b and c, and divide everything by the determinant (ad-bc). A matrix A is orthogonal if itstranspose is equal to it inverse. Inverse of a Matrix Definition. Now the question arises, how to find that inverse of matrix A is A-1.
