MATHEMATICS NOTES CHAPTER- 2
Points to Remember
We have provided some important points that are covered in NCERT Class 11 Maths Chapter 2 to help students in their exam preparations. Refer to the list below:
An ordered pair consists of two objects or elements in a given fixed order.
(a1, b1) = (a2, b2) ⇔ a1 = a2 and b1 = b2
If A and B are two non-empty sets, then A × B = {(a,b) : a ∈ A, b ∈ B} is called the Cartesian product of A and B.
If A and B are finite sets having m and n elements respectively, then A × B has mn elements.
R × R = {(x, y) : x, y ∈ R} is the set of all points in the XY-plane.
R × R × R = {(x, y, z) : x, y, z ∈ R} is the set of all points in three-dimensional space.
If A and B are finite sets having m and n elements respectively. Then, 2mn relations can be defined from A to B.
Topics and Sub-topics
The chapter consists of 3 exercises with 6 topics. Notes to 13 questions of exercise 2.1, 9 questions of exercise 2.2, and 5 questions of exercise 2.3 have been given. The answers to miscellaneous exercise questions are also made available to the students. Before knowing the NCERT notes for chapter 2 of Class 11 Maths, here is an overview of the important topics:
