NCERT Solutions for Class 12 Maths Chapter 3: Points to Remember

Every chapter has some important points and highlights that give a gist of the topics covered in it. Students can refer to them while revising their concepts. They can find the important points to remember for this chapter below.

• A set of numbers (real or imaginary) or symbols or expressions arranged in the form of a rectangular array of m rows and n columns is called m×n matrix.
• A square matrix A=[aij]n×n is called an identity or a unit matrix, if aij=0 for all i≠j and aij=1 for all i=j.
• Commutativity: If A and B are two matrices of the same order, then A+B=B+A.
• Associativity: If A,B,C are three matrices of the same order, then (A+B)+C=A+(B+C).
• Existence of Identity: The null matrix is the identity element for matrix addition i.e., A+O=A=O+A
• Existence of Inverse: For every matrix A=[aij]m×n, there exists a matrix −A=[−aij]m×n, such that A+(−A)=O=(−A)+A
• Cancellation Laws: If A,B,C are three matrices of the same order, then A+B=A+C⇒B=C and, B+A=C+A⇒B=C
• In order to find the inverse of a non-singular square matrix A by elementary operations, we write A=IA or A=AI
• We perform a sequence of elementary row operations successively on A on the LHS and the pre-factor I on RHS till we obtain. The matrix B, so obtained, is the desired inverse of matrix A.
