# NCERT Solutions Class 11 Maths Chapter 2 Exercise 2.1 Relations and Functions

NCERT Solutions for Class 11 Maths Chapter 2 Exercise 2.1 Relations and Functions explains the basics related to the Cartesian product of sets. Given two non-empty sets P and Q. The cartesian product P × Q is the set of all ordered pairs of elements from P and Q, i.e., P × Q = { (p,q) : p ∈ P, q ∈ Q }. There are a few conclusions drawn from this definition that make their way into the exercise. The first is that two ordered pairs are equal, if and only if the corresponding first elements are equal and the second elements are also equal. Secondly, if A and B are non-empty sets and either A or B is an infinite set, then so is A × B. This exercise also involves questions based on recognizing ordered pairs.

A basic understanding of Relations and Functions is a must for solving all the questions present in this exercise. Class 11 Maths NCERT Solutions Chapter 2 comprises a wide range of questions based on this topic with practical examples.
