Sets is the first chapter covered under the new NCERT syllabus Class 11 maths. As a basic concept in mathematics, Sets are basically a technique to group together similar objects, classify various such groups and define relations shared between them. Sets can be made of practically anything. However, for any group or collection to be adjudged a set in terms of maths, the set's range or contents need to be well defined.
For example, all months in the calendar starting with J, all letters in the English Alphabet system, and all integers within a given range are examples of a set. However, collections such as the most talented artists globally and the most brilliant minds in India that do not have a welldefined range cannot be called a set. Sets are diagrammatically represented using Venn Diagrams.
