As we know the formula of inverse for 22 matrix is given by. To calculate the determinant of a 22 matrix multiply the elements of the 22 matrix on the main diagonal and subtract the product of the elements on the secondary diagonal. Swap the positions of a and d put negatives in front of b and c and divide everything by the determinant ad-bc.

Its submitted by organization in the best field. In the function determinant if the size of the matrix is 2 then the determinant is directly calculated and the value is returned. The determinant of matrix A is calculated as If you cant see the pattern yet this is how it looks when the elements of the matrix are color-coded.
