SSC Mathematics Note 2nd Chapter Set and Function.
The word set is familiar to us, such as dinner set, set of natural numbers, set of rational numbers etc. As a modern weapon of mathematics, the use of set is extensive. The German mathematician Gorge Cantor (1844 –1918) first explained his opinion about the set. He created a sensation in mathematics by expressing the idea of infinite set and his conception of set is known as set theory’. In this chapter, the main objectives are to solve problems through using mathematics and symbols from the conception of the set and to acquire knowledge about function.Well defined assembling or collection of objects of the real or imaginative world is called sets, such as the set of three textbooks of Bangla, English, and Mathematics, set of first ten natural odd numbers, set of integers, set of real numbers, etc.
