Set & Functions

This chapter talks about sets. Here, we will learn to describe or specify a set. Finite and infinite sets, equal and equivalent sets, intervals as subsets of R, etc., are explained. We will also understand operations on sets and complement of a set.

This chapter deals with relations and functions. We will study ordered pairs and the equality of two ordered pairs. Cartesian products of two sets are discussed here. Graphs of some functions and operations of functions are also explained.
