This chapter covers certain fundamental set concepts and processes. To summarise, a set is a predefined group of objects. The term "empty set" means that a set has no elements. A finite set has got a finite number of elements; likewise, an infinite set has got an infinite number of elements. Two sets, A and B, are considered to be equal if their elements are the same. If any element of A is also an element of B, then set A is a subset of set B. Intervals are R's subsets. All subsets of set A make up a power set of that set. It is denoted by the letter P(A). The intersection of two sets, A and B, gives all the common elements to both sets. The union or summation of two sets, A and B, is the set of all elements either in A or B. The group of elements that belong to A but not to B is the distinction between two sets, A and B, in this order. The set of all elements of U that are not the elements of A is the complement of a subset A of universal set U. (A B) ′ is equal to A′ B′ and (A B) ′ equals A′ B′
Here you can find RD Sharma Solutions for Class 11 Maths Chapter 1- Sets. We begin with two undefined (or primitive) words in this chapter: "part" and "set." The term "collection" is synonymous with "set," "aggregate," and "class". A collection is made up of elements. The terms "part," "object," and "member" are interchangeable. Our expert faculty team covers all of these topics in the RD Sharma Solutions for Class 11 PDF. Tutors have created ideas creatively and lucidly, which would make it easier for the students to grasp the concepts.
