• Determinant of a matrix A [a11] 1×1 = is given by | a11 |= a11

• Determinant of a matrix A

• Determinant of a matrix

is given by (expanding along ( R1)

• For any square matrix A, the |A| satisfy following properties.

• |A′| = |A|, where A′ = transpose of A.

• If we interchange any two rows (or columns), then sign of determinant changes.

• If any two rows or any two columns are identical or proportional, then value of determinant is zero.

• If we multiply each element of a row or a column of a determinant by constant k, then value of determinant is multiplied by k.

• Multiplying a determinant by k means multiply elements of only one row (or one column) by k.

•If A= [ aij ]3×3 , then |k. A| =k3 | A |

• If elements of a row or a column in a determinant can be expressed as sum of two or more elements, then the given determinant can be expressed as sum of two or more determinants.

• If to each element of a row or a column of a determinant the equimultiples of corresponding elements of other rows or columns are added, then value of determinant remains same.

• Area of a triangle with vertices ( x1, y1 ), ( x2, y2 ) and ( x3, y3 ) is given by

• Minor of an element aij of the determinant of matrix A is the determinant obtained by deleting th i row and th j column and denoted by Mij

• Cofactor of aij of given by Aij = (– 1)i+ j Mij

• Value of determinant of a matrix A is obtained by sum of product of elements of a row (or a column) with corresponding cofactors. For example, |A| = a11 A11 + a12 A12 + a13 A13 .

• If elements of one row (or column) are multiplied with cofactors of elements of any other row (or column), then their sum is zero. For example

• If elements of one row (or column) are multiplied with cofactors of elements of any other row (or column), then their sum is zero. For example, a11 A21 + a12 A22 + a13 A23 = 0

• A (adj A) = (adj A) A = | A | I ,where A is square matrix of order n.

• A square matrix A is said to be singular or non-singular according as |A|| = 0 or |A| ≠ 0.

• If AB = BA = I, where B is square matrix, then B is called inverse of A. Also A-1 = B or B-1 = A and human (A-1)-1 = A

• A square matrix A has inverse if and only if A is non-singular.

• If a1x + b1y + c1z = d1

• a2x + b2y + c2z = d2

• a3x + b3y + c3z = d3

• then these equations can be written as A X = B, where

• Unique solution of equation AX = B is given by X = A-1 B, where | A| 0 ≠ 0

• A system of equation is consistent or inconsistent according as its solution exists or not.

• For a square matrix A in matrix equation AX = B

• ||A| ≠ 0, there exists unique solution

• |A| = 0 and (adj A) B ≠ 0, then there exists no solution

• |A| = 0 and (adj A) B = 0, then system may or may not be consistent.
