CHAPTER 4 :- Determinants |
S.No |
Explanation of the Topics |
1 |
First of all teacher will start the session by
asking certain questions of matrices. Then introduce the topic determinant. Now teacher will help the students in finding the
determinant of 2 x 2 matrices and 3 x 3 matrices. Definition
of Determinant Determinant is a number associated with the
square matrix. To every square matrix A = [aij] of
order n, we can associate a number (real or complex) called determinant of
the square matrix A. Determinant of matrix
[A] is denoted by |A| |
2 |
Properties of Determinants Now teacher will explain
all the properties of determinants with the help of examples and apply them
in different problems. Teacher will provide sufficient number of problems to
the students for practice. |
3 |
Concepts of minor and cofactor Now teacher will
introduce the concept of minor and Determinant and will explain the
method of finding the minors and cofactors. Students will be given sufficient
method of finding the determinants by using the cofactors. |
4 |
Area of Triangle Now teacher will explain
the method of finding the area of the triangles by using determinants. |
5 |
Adjoint and Inverse of a Matrix First of all
teacher will explain the definition of Singular matrices, invertible matrices
and Adjoint of a matrix. Singular Matrix:
A matrix whose determinant is equal to zero is called a singular
matrix. If determinant is not equal to zero then it is called Non-Singular
Matrix. Invertible Matrix: A
matrix is said to be invertible if it is non-singular. Now teacher will explain
the method of finding the Adjoint and inverse of the square matrices. |
6 |
Consistency and and Inconsistency of
system of linear equations. Teacher will Discuss and
Explain the consistency, inconsistency and the number of solutions of the
system of linear equations with two or three variables. |
7 |
Solution of System of Linear Equations Now teacher will explain
the method of solving the system of linear equations in two or three
variables by using Adjoint method of finding inverse of matrix method. |
