00:58 Binary relation is a subset of the Cartesian product of two sets

01:56 The relation R is defined as the set of ordered pairs where the elements are equal to each other.

02:54 Relation R is created with ordered pairs where the first element is equal to the second element.

03:52 Relation R represents a mapping from a set A to itself.

04:50 The relation R consists of ordered pairs where the first element divides the second element.

05:48 The number of relations on a set with n elements can be found by listing down all the subsets of A x A.

06:46 The number of relations on a set A with n elements is equal to 2 to the power n square.

07:39 The number of relations on a set A with n elements is 2 to the power n square.

@krisretro

Thank you Sir. I watched this video a while back to understand relations, now I am watching this again to revise before an exam.

@shobhitagrawal4901

Sir, please Complete Data Structures πŸ™ I have started studying from the playlist and its important from my semester point of view

@baborsregime9922

this channel makes concepts easy in a very short video

@chetankembhavi4810

Let A={1,2,3,4} and let R be the releation on A  defined by   xRy if and onlyif  " x divides y"  written x/y.
1) write down R as a set of ordered pairs.
2) draw digraph of R.
3) determine the indegree and outdegree vertices of digraph. Solve this problem please send me answer

@lanitaslove

thank u this helped for my finals!!!😁

@aarjitlamsal2768

Thanks I was confused and now I understand

@freeblade5296

Can u pl explain the purpose of math in this world cuz we don't need these super hard lessons In life ( THE WORLD IS STUPID AS A GOAT)

@CharmingMoments09

Thank you Very much Sir
Your Videos are very helpful
Great explanation Sir

@themid9itegamer9

Thank you
To be honest the last part really wasn't so easy to understand, but I mixed it with a bit of Google and I'm good to go now.

@RealAXork

If I am not mistaken, in my university we defined a relation specifically as a non-empty subset of AxB. I wonder why this is? I cannot find this definition elsewhere.

@etacalistus1727

Well understood. Thank you very much. Never saw graphical representation of relations before. You've cleared my doubt. But why is 5 not mapped to 6 also  rather just to itself?

@BalukuAbdulRahhman

i have really enjoyed this lecture, thank u sir

@nicholaspratte3170

You are such an excellent teacher, keep up the good work!
