5. What is the use of Matrices according to Chapter 3 of Class 12 Maths?

Chapter 3 of Class 12 Maths is regarding Matrices. This is a type of numerical where you will get a few numbers or elements arranged inside the third brackets. You will be able to perform addition, subtraction, multiplication, etc. on the matrices. The use of learning matrices is their application in the area of vectors. When you study vectors, you will have to transform the linear equations to and from the vector field. So this becomes important to study and understand this chapter well.

6. How do you determine the number of elements from a matrix?

The Chapter 3 Matrices of Class 12 will introduce you to a few new terms among which elements are one. Elements are the numbers arranged in rows and columns inside a matrix bracket. The number of elements can be very easily determined or calculated by simply multiplying the number of rows with the number of columns present inside the third bracket. This will give the number of total elements inside the matrix. For example, if there are three rows and four columns then the number of elements will be 3*4= 12.

7. How can the order of a matrix be calculated?

Order of the matrix is basically the representation of the matrix in terms of rows and columns. If there are m number of rows in a matrix and n number of columns, then the order of the matrix will be written as m*n. The order of the matrix is important since it helps us to calculate the number of elements and also to understand the nature of the matrix. The order of matrices needs to be similar in order to be able to equate two or more numbers of matrices. If the order is not the same then it cannot be equated.

8. What happens to the elements of two different matrices when the matrices are equal?

When you have two equal matrices, with an equal sign given in between them, then we will know that the corresponding elements of those two matrices are equal as well. For example, if the first element of the first matrix is two and the first element of the second matrix is unknown that is represented as ‘x’ then the value of x will be equal to two. This is how we can find the unknown elements from equal matrices.

9. Is the Matrix Chapter important for boards?

Yes, the Matrix Chapter from Class 12 is very important. This is because every year there are guaranteed questions from this chapter that come in your board exam. So it becomes necessary to have clear concepts in this Chapter and also be perfect with the sums from this Chapter. If you practice all the NCERT questions and solutions then it will become easier for you to score well in the Maths Class 12 exam.
