Sets

समुच्चय

In Class 11 Mathematics, the chapter Sets introduces collections of well-defined objects and the language used to describe them. Students learn ways to represent sets, identify elements, distinguish finite and infinite sets, and understand subsets, universal sets, and empty sets. The chapter also develops operations such as union, intersection, difference, and complement, often using Venn diagrams to solve problems and express relationships between sets clearly.
