Describe Minors And Cofactors.

1.	Describe Minors And Cofactors.
Answer» The minors and cofactors are the important concepts used to determine the adjoint and hence, the inverse of a matrix. Minor of an element is defined as the determinant obtained by deleting the row and column in which that element lies in the matrix. They are one of the most important concepts to determine the adjoint of a matrix. The minors when multiplied by (-1)^{i + j}gives the cofactors, where i is the row number and j is the column number. Let's understand in detail.
