If A and B are two non-empty sets, then a relation R in A x B is a subset of A x B. If we use the letter R to denote a relation, then we can write the relation between a and b as aRb a is related to b. Let R mean 'is greater than', then xRy mea..

Properties of Relations
Properties of Relations - Consider the set A = {a, b, c, } then any subset of A x A is called a relation in A. Let R be any relation in A so that R is a subset of the product set A x A. We will discuss the properties a relation may possess..
Relations and Functions
A relation R is a non-empty sub-set of a cartesian product. A relation is a set of ordered pairs, i.e., R A x B where A and B are two non-empty sets. Domain of a relation is the set of all first components. ..
Representation of a Relation
Relations are Represented by: (i) Roster form (ii) Set builder form (iii) By tables (iv) Arrow diagram (v) By grap..
Properties of Relations
Reflexive property: A relation R in a set A is said to be reflexive if every element of the set A is related to itself. This is if aRa where a A, or (a, a) R for each a A. Transitive property: A relation R, is said to be tra..

Introduction - In Mathematics, a well-defined collection of definite objects is called a set. George Cantor is regarded as the "Father of Set theory". The concept of "Sets" is basic in all branches of mathematics. It has proved to be of particular importance in the fou..

I love the interaction and ability to explain the process of math problem in depth! Would like see the same for all future lessons one on one! THANK YOU!!!
Very good, Tutor was clear and guided me through the whole algebra problems
Tutor Vista tutor helped me understand and gave me some practices and showed me how to do them.
The tutors are amazing. They are very committed in helping students solve the questions and explains all the steps beautifully. So 5 stars for Tutor Vista.
