RELATIONS- REFLEXIVE/SYMMETRIC/TRANSITIVE/EQUIVALENCE RELATIONS

  Learn what is a relation from scratch. Understand the types of relations, namely,

reflexive,

symmetric and

transitive.

What are equivalence relations, equivalence classes and learn how to solve problems based on these. 

 Understanding Relations is the first step to understanding functions.

UNDERSTANDING THE DOMAIN AND RANGE OF A FUNCTION

Welcome to this lesson on Domain and range of a function. This is a part of Relations and Functions/Class 11 Maths. Understanding Domain and Range of a function plays an important role in Inverse Trigonometric functions and in Calculus. Here, you will learn about functions, their domain, codomain and range. A number of problems are explained . The interesting fact about algebraic functions-domain and range is that each problem follows a different approach. As I tell my students, you have to practice each problem to understand it better.
