Clarified everything with num of relations and sets!!!

I think this is one of the best online classes for maths

jeril

One of the best videos I have seen in recent times
No time pass, no time promo, just straight facts and goated explanation
Surely gonna share it with everyone

sir, i think it should be "total number of relations defined on A" instead of "on AxA".

If a relation is defined on A, it means
R: A -> A

If a relation is defined on AxA, it means
R: AxA -> AxA

If a relation is defined from A to B, it means R: A -> B

If relation is defined on AxB, it means R: AxB -> AxB

Thanks a lot sir
I’m in class 12 and It’ll help me a lot in Jee
You’re really amazing sir

Sir,
Anti symmetric relation has come today in CMI Bsc paper, I did it because of you and only you. Exactly same nothing different when you see the paper of CMI 2020 you will realise it. I just copied and pasted there.

Thank you very much Sir
I was very much struggling with this topic but now I'm fine in this topic

Thank you sir for your excellent explanation.

Thank you sir for jee mains 2023
My teacher give me only direct give me clarity

Nice explanation of the concept involved, thank you so much for your time and effort.

Sir I think you should not count diagonal elements in the counting of anti symmetric relations... As it converses itself, If (a, a) is present then (a, a) should not present...

Nice explanation but Bn ki values kahan se li?

Can anyone answer me that what is the number of relations that are not antisymmetric on a set with n elements?

muhammadharis

Can we write: No. Of anti-symmetric relations = Total No. Of relations - No. Of symmetric relations. ??

Relation xRy is antisymmetric if X =y
