Consider the matrix A = 3 (a) Compute the adjoint matrix adj(A). (b) Compute the determinant det(A) and find the inverse matrix A-¹, Consider the matrix B= 2 1 (a) Use the cofactor exapansion to evaluate the determinant det(B) with using the second column. (b) Use the cofactor exapansion to evaluate the determinant det(B) with using the third row.
