 Properties of Determinants

 Property 1: When the determinant’s columns and rows are swapped, the determinant’s value stays unaltered.
 Property 2: When any two columns or rows of a determinant are swapped, the sign of the determinant changes.
 Property 3: The determinant value is zero when two columns or rows of a determinant are equal and have the same associated elements.
 Property 4: When each element of a determinant’s column or row is multiplied by a constant K, the value is multiplied by constant K as well.
 Property 5: A determinant can be expressed as the sum of two or more determinants if some or all elements in a column or row are expressed as a sum of two or more terms.
 Property 6: When the equimultiples of the corresponding elements of other columns or rows are added to each element of any column or row of a determinant, the value of the determinant remains the same, i.e., the value of the determinant remains the same if the operation is applied.
 Property 7: If each column or row element is 0, the determinant’s value is zero.
 Property 8: If all the components on one side of the principal diagonal are zero, the determinant’s value equals the product of the elements on that side of the principal diagonal.

 Adjoint and Inverse of a Matrix

 Theorem 1: When A be any given Square Matrix of order n, then A(adj A)=(adj A)A= AI (Singular and NonSingular Matrix)
 Theorem 2: When A and B are nonsingular matrices of the same order, then AB and BA are also nonsingular matrices of the same order.
 Theorem 3: The determinant of the product of matrices is equal to the product of their respective determinants, that is, AB= A B, where A and B are Square Matrices of the same order.
 Theorem 4: A square matrix A is invertible if A is a nonsingular matrix.
