Question

write two significance of minor and cofactor of a determinant.............. don't copy or spam✖✖✖​

Answer 1

Step-by-step explanation:

Minors and cofactors are two of the most important concepts in matrices as they are crucial in finding the adjoint and the inverse of a matrix. To find the determinants of a large square matrix (like 4×4), it is important to find the minors of that matrix and then the cofactors of that matrix.
