WebConclusion. The inverse of A is A-1 only when AA-1 = A-1A = I. To find the inverse of a 2x2 matrix: swap the positions of a and d, put negatives in front of b and c, and divide everything by the determinant (ad-bc). Sometimes there is no inverse at all. WebDefinition. A matrix A is called invertible if there exists a matrix C such that. A C = I and C A = I. In that case C is called the inverse of A. Clearly, C must also be square and the same size as A. The inverse of A is …
