 Introduction  Much of mathematics is about finding a  pattern a recognisable link between quantity that change. In our daily life we come across many  patterns that characterise relation such  as brother and sister , father and son ,  teacher and student . We will learn how to link pairs of objects  from two sets and then introduce  relations between the objects in the pair.  Finally ,we will learn about special  relations which will qualify to be  functions . The concept of functions is  very important in mathematics since it  captures the idea 💡 of a mathematically  precise corresponding between one  quantity with the other

  Introduction   The concept of set serves as a fundamental part of the present day mathematics . Today this concept is being used to geometry , sequences , probability, etc . Requires the knowledge of sets . Georg cantor (1845-1918)
