Ch.2. Cartesian Product of Sets and Relations - Part 2
Concept Review
2.2 Relation
Let A and B be two sets. Then a relation R from A to B is a subset of A×B.
R is a relation from A to B => R is a subset of A×B.
Total number of relations: If A and B are two non empty sets with m and n elements respectively, A×B consists of mn ordered pairs.
Since each subset defines a relation from A to B, so total number of relations from A to B is 2mn.
2.3 Types of relations
Void relation
Universal relation
Identity relation
Reflexive relation
Symmetric relation
Transitive relation
Antisymmetric relation
Equivalence relation

_____________
_____________
He taught English and Mathematics with passion.
You were a light
that always glowed bright
You were a scholar erudite
gave your students insight
You had knowledge might
used to it well to write
notes and essays right
that brought students delight
You had the foresight
to plan and excite
your children and students to recite
poems full of wisdom and wit
