Let A be an nxn matrix. Determine whether the statement below is true or false. Justify the answer. The (ij)-cofactor of a matrix A is the matrix A, obtained by deleting from A its ith row and jth column. Choose the correct answer below. O A. The statement is false. The (i.j)-cofactor of A is the number C = (- 1)'*'det(A), where A is the submatrix obtained by deleting from A its ith row and jth column. O B. The statement is false. The (ij)-cofactor of a matrix A is the matrix Aj obtained by deleting from A its įth row and ith column. O C. The statement is false. The (i,j)-cofactor of A is the number C = det (A), where Aj is the submatrix obtained by deleting from A its ith row and jth column. O D. The statement is true. It is the definition of the (i,j)-cofactor of a matrix A.

Matrices

‘Matrices’ is the plural form of the word matrix, and it is basically a spreadsheet in the form of a box. In mathematics, various functions can be carried out with matrices. Generally, a matrix comes in the shape of a square or rectangle. The elements are distributed horizontally in the form of rows, and vertically in the form of columns.
