NCERT Solutions for Class 11 Maths Chapter 2- Relations and Functions

iacst-2022

In the NCERT Solutions by Aakash for Class 11th Maths Chapter 2 "Relations and Functions", the topics that students need to practice are the definition of Relation; Ordered pairs; Domain, Co-Domain, and Range of a Relation. The topics Cartesian Product of Sets, Number of elements present in the Cartesian product of two finite sets, and pictorial representation via Diagrams are also very important.

Under Functions part, topics that are taught are how to pictorially represent a function; how a function is a special type of relation; domain, co-domain, and range of functions, real-valued functions. The domain and range of these functions; identity, rational, constant, modulus, polynomial, exponential, logarithmic, signum, and the greatest integer functions plus their graphs are also taught to the students in this chapter. What students will be getting to know about in this chapter is how relations and functions are different from each other and how pairs of objects from two sets are linked, and a relation between the two objects present in pairs is formed.

Topics under the Relations and Functions chapter are briefly explained below.

  • Cartesian Product of Sets

Under this topic, the meaning of the Cartesian product and ordered pairs has been defined with the help of real-life models as examples, and how to present them.

  • Relations

Relations show the mapping of a set to another set, say Set A to Set B. Also introduced in this topic are the concepts of domain and co-domain.

  • Functions

Under this part, the definition of the function, how functions are visualized, and how a relationship can be a function has been explained. Image and preimage theories are also made clear under this topic.
