NCERT Solutions for Exercise 4.3 Class 12 Maths: Important Topics

In Class 12 Maths Chapter 4 Determinants, students learn that a determinant is a number that can be calculated for only square matrices. Determinants play an essential role in solving linear equations to check whether a certain system of equations has any unique solution or not. Determinants have several real-life applications in science, social sciences, engineering, etc. 

Exercise 4.3 Class 12 Maths NCERT Solutions explains various calculations such as finding the determinant of a 2×2 matrix, 3×3 matrix, determining the area of a triangle, finding the equation of a line using a determinant, cofactors and minors. Before moving on to the Class 12 Maths NCERT Solutions Exercise 4.3, students can check the overview of this chapter and learn the sub-sections they will be studying later. 

NCERT Solutions for Exercise 4.3 Class 12 Maths: Important Points to Remember

Below we have provided some of the Chapter 4 important points to remember for NCERT Class 12 Maths Exercise 4.3 to ace your exams:

• If any two rows or columns of a determinant are identical, then its value is zero.
• If each element of a row (column) of a determinant is zero, then its value is zero.
• For a system of linear equations with two variables, determinants become 2×2 matrices.
• If A and B are square matrices of the same order, then |AB|=|A||B|
• Let A=[aij] be a square matrix of order n, and let BB be the matrix obtained from AA by multiplying each element of a row (column) of AA by a scalar k, then |B|=k|A|.
