http://samacheerkalvi.net/ 1 SETS AND FUNCTIONS A set is Many that allows itself to be thought of as a One - Georg Cantor Introduction Sets 1.1 Introduction The concept of set is one of the fundamental concepts Properties of set operations in mathematics. The notation and terminology of set theory De Morgan’s Laws is useful in every part of mathematics. So, we may say that Functions set theory is the language of mathematics. This subject, which originated from the works of George Boole (1815-1864) and Georg Cantor (1845-1918) in the later part of 19th century, has had a profound influence on the development of all branches of mathematics in the 20th century. It has helped in unifying many disconnected ideas and thus facilitated the advancement of mathematics. In class IX, we have learnt the concept of set, some GeorGe Boole operations like union, intersection and difference of two sets. Here, we shall learn some more concepts relating to sets and (1815-1864) England another important concept in mathematics namely, function. First let us recall basic definitions with some examples. We Boole believed that there wasa close analogy between symbols that denote all positive integers (natural numbers) by N and allrepresent logical interactions and real numbers by R .algebraic symbols. 1.2 Sets He used mathematical symbols Definitionto express logical relations. Althoughcomputers did not exist in his A set is a collection of well-defined objects. The objectsday, Boole would be pleased to in a set are called elements or members of that set.know that his Boolean algebra Here, “well-defined” means that the criteria foris the basis of all computer arithmetic. deciding if an object belongs to the set or not, should be As the inventor of Boolean defined without confusion.logic-the basis of modern digital For example, the collection of all “tall people” incomputer logic - Boole is regarded in Chennai does not form a set, because here, the deciding criteriahindsight as a founder of the field of “tall people” is not clearly defined. Hence this collection doescomputer science. not define a set.
