Co-factor matrix:When a certain element is in the shape of a square or rectangle, the row and column of that element are eliminated to get a number known as a cofactor. Depending on the element's position, a positive or negative sign...
The inverse of the 3x3 matrix can be determined by calculating the determinant and matrix of cofactors and then dividing each term by determinant. Learn more at BYJU'S.
Step 3: Find the adjoint of AThe adjoint of a matrix is the transpose of the cofactor matrix. We will calculate the cofactors for each element in A. 1. Cofactor C11: C11=det[32−3−4]=(3)(−4)−(2)(−3)=−12+6=−6 2. Cofactor C12: C12=−det[22−3−4]=...
