NCERT Solutions for Class 12 Maths Chapter 3
Matrices deals with arranging and organizing them in a proper form of a table. In our NCERT Solutions for Class 12 Maths Chapter 3, students will also learn about various ways to apply matrices with determinants. This chapter covers all aspects of matrices with their types, operations, and applications.
Let us discuss the sub-topics in detail.
It simplifies our work to a great extent when compared with other straight forward methods. Matrices are not only used as a representation of the coefficients in the system of linear equations but also used in a personal computer.
A matrix is an ordered rectangular collection of numbers or functions. These numbers are called the elements or the entries of the matrix. It contains some Rows and Columns.
3.2.1 Order of Matrix
Each matrix has m rows and n columns. Its order is m × n and we read it as an m by n matrix.
3.3 Types of Matrices
This topic discusses various types of Matrices as Column Matrix, Row Matrix, Square Matrix, Identity Matrix, etc.
3.4 Operations on Matrices
It introduces some basic but important operations on matrices, like the addition of matrices, multiplication of a matrix by a scalar, difference, and multiplication of matrices, etc. Also, it explains various properties of matrices based on these operations.
3.4.1 Addition of Matrices
It elaborates the process to add two matrices.
3.4.2 Multiplication of a matrix by a scalar
It elaborates the process to multiply a matrix by a scalar quantity.
3.4.3 Properties of matrix addition
It shows some additive properties of matrices.
3.4.4 Properties of scalar multiplication of a matrix
It shows some multiplicative properties of matrices.
3.4.5 Multiplication of matrices
It elaborates the process to multiply two matrices.
3.4.6 Properties of multiplication of matrices
It shows some multiplicative properties of matrices.
3.5 Transpose of a Matrix
It explains the meaning and procedure of finding the transpose of a matrix. It plays the main role to define and find the symmetric and skew-symmetric matrices.
3.5.1 Properties of the transpose of the matrices
It explains some properties of the transpose of matrices.
3.6 Symmetric and Skew-Symmetric Matrices
It defines two more types of matrices which used to get some interesting results.
3.7 Elementary Operation (Transformation) of a Matrix
It explores the elementary transformations of the matrices. There are six transformations possible on a matrix, three of which are due to rows and three due to columns.
3.8 Invertible Matrices
It defines the existence of inverse of a matrix. This inverse matrix exists and gives the identity matrix after multiplying it with the original matrix, if it exists, it will be unique.
3.8.1 Inverse of a matrix by elementary operations
It discusses the elementary operations on the inverse of a matrix.
