Key Features of NCERT Solutions for Class 11 Maths Chapter 1- Sets

This chapter contains 6 exercises and a miscellaneous exercise with the help of which students get detailed knowledge about the concepts of Sets of the first term Class 11 Maths CBSE Syllabus (2021-22).

The summary of the topics which are explained in NCERT Solutions for Class 11 Chapter 1 Maths are as follows:

1. A set is defined as a well-defined collection of objects.
2. Any set which does not contain any element is known as an empty set.
3. Finite set: A set that contains a definite number of elements is known as a finite set.

Infinite set: A set that contains an infinite number of elements is known as an infinite set.

1. If sets A and B have the same number of elements then sets A is equal to sets B.
2. If every element of set A is also an element of set B then set A is a subset of set B. So, Intervals are said to be subsets of R.
3. The collection of all subsets of A is a power set of a set A. The power set is denoted by P(A).
4. The set of all those elements which are either in set A or set B is the union of two sets A and B.
5. The set of all those elements which are common in set A and set B are the intersection of two sets A and B. And the set of all those elements that belong to A but not B is the difference between the two sets A and B.
6. The set of all elements of U which are not the elements of A is the complement of a subset A of universal set U.
7. For the set A and set B, (A ∪ B)’ = A′ ∩ B′ and ( A ∩ B )′ = A′ ∪ B′.
