From Nigeria, FUTA, this tutorial and that of Algorithm saved a whole faculty😅😅. Nice one really!!!
😂😂 we gather Dey
He's Indian
Much more short and straighforward explanation. Appreciated🌸
Gm
Concise and to the point. Thanks
You have just ruined professor's one hour lecture in 6 minutes
*2 hour
*5 hours
whole semester
Whole career
Whole life😂
Clear and easy to understand . thanks sir
Your video is best one for relation examination
SAVED MY LIFEEEEEEEEEEEEEEEEEEEEE
Century complete re baba
Thanks neso academy and specially Jaspreet sir 🙏
Thanks sir , your way of explaining is fantastic
This is very helpful
Much needed video 🎉
thank you so much for these videos, i should have skipped my 2 hour long professor lecture where i understood nothing and just watched this instead
FR
yours vedios are well explained,, so please give vedios for functions in maths
damn i was about to fail the class agter watching your video i am the one who wish to get A on the exam damn what a transition..You really explain good..
thank you!!!!
Great 👍
This helped me alot. Thank You~
Super smooth
Thanks bro
Character In the video It's great, I like it a lot $$
Tomorrow is my paper and i complete whole syllabus in just 6 min video🤣
Love you sir
God bless you🎉🎉🎉
Great work appreciated
question: why isn't there (1;3)??
really nice sir thank you
Thanks
Bro tysm
good so good👍👍👍🍀
Hats off
Itna acha itna smoothly 👌
Thank you for the video
When you say "as simple as that", it hits me lol🤣, doubting if i am supposed to be that intelligent in first go 😇
So a=b means it is not symmetric but anti symmetric?
Excellent
Very good explanation 😊
The first ex given for irreflexive relation is not irreflexive but is it reflexive or not
explained it better than my prof lol 10/10
Is there any relation which is not reflexive, not irreflexive and not antisymmetric
Holy shit I love you. My brain finally understands symmetric vs antisymmetric
Hi I am not understanding the example on Antisymmetric, shouldn't it be that THAT example is NOT Antisymmetric?
Topic explaination is very good
4:06 ....... Why we need not to check for (1, 1), (2, 2)
Sir please upload videos on DBMS
I am from India
How is anti-symmetric different from non-symmetric?
Consider a relation
R = { (1,1) , (1,2) , (3,1) , (1,3) }
Here R is not symmetric because ,R is symmetric if there exists a,b then there should be b,a since R contains 1,2 but not 2,1 R is not symmetric
However , R is also not Antisymmetric because , R is Antisymmetric if it contains a,b but not b,a ( note : it can have a,a as an ordered pair ) since in our example there exists 3,1 as well 1,3 which is not allowed in antisymmetric relation and
Hence,
Antisymmetric is not always equal to (not symmetric)
I hope you got it!
Thanku so much sir
Thanks, very informative! But I wanna ask if r = {(1,1), (2,2), (3,3), (4,4)} considered symmetric? if yes, please explain because I can't wrap my head around it
2:33 it is identity relation
Thank you so much sir ❣️❣️☺️💗
Yor boss
Thank you sir
❤❤
Oke)
❤
Sir can I conclude that antisymmetric is equal to not symmetric
No you cannot because ,
Consider a relation
R = { (1,1) , (1,2) , (3,1) , (1,3) }
Here R is not symmetric because ,R is symmetric if there exists a,b then there should be b,a since R contains 1,2 but not 2,1 R is not symmetric
However , R is also not Antisymmetric because , R is Antisymmetric if it contains a,b but not b,a ( note : it can have a,a as an ordered pair ) since in our example there exists 3,1 as well 1,3 which is not allowed in antisymmetric relation and
Hence,
Antisymmetric is not always equal to (not symmetric)
I hope you got it!
You're gods
"gods" 💀
Very helpful sir thank you sm
Thank you so much sir.
Sir please upload more videos. They are helping me too much
Sir what happened to the gate aptitude series ? plzz sir upload the continuation videos
👇Opt math attendance❤❤
Data structures...
Please upload and complete DS Course.
awesome
Nice
Plz regularly upload videos on DBMS series ✌️✌️🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
Do u mean dms?

My brain is not braining

i haven't understand which you have explained its not clearly explain
Let me explain you,
Antisymmetric = { (1,1) , (1,2) , (2,3) }
Here if 1,2 ( say a,b ) exists then 2,1 ( that is b,a ) is not allowed , however if 1,1 ( say a,a ) exists then 1,1 ( agai a,a ) is allowed
Assymetric = { (1,2) , (2,3) , (3,1) }
Here if (a,b) exists then (b,a) is not allowed, also (a,a) is not allowed
Consider a relation
R = { (1,1) , (1,2) , (3,1) , (1,3) }
Here R is not symmetric because ,R is symmetric if there exists a,b then there should be b,a since R contains 1,2 but not 2,1 R is not symmetric
However , R is also not Antisymmetric because , R is Antisymmetric if it contains a,b but not b,a ( note : it can have a,a as an ordered pair ) since in our example there exists 3,1 as well 1,3 which is not allowed in antisymmetric relation and
Hence,
Antisymmetric is not always equal to (not symmetric)
I hope you got it!
if a relation is not irreflective .is reflective????
Not necessary, if some elements in a set are {a,a} and some are {a,b}, then its not reflective as {a,b} exists but it isn't irreflective either since {a,a} exists. It has to be all elements following the requirement.
When will part 2 be released?
Dbms and ds pls
DBMS
👍👍👍👍
So fast
“Let me tell you”❤
Please start teaching CO SUBJECT as soon as possible
Antisymmetric?
never heard of that when i was studying PU i thought the last one was Transitive relations
Let me explain you,
Antisymmetric = { (1,1) , (1,2) , (2,3) }
Here if 1,2 ( say a,b ) exists then 2,1 ( that is b,a ) is not allowed , however if 1,1 ( say a,a ) exists then 1,1 ( agai a,a ) is allowed
Assymetric = { (1,2) , (2,3) , (3,1) }
Here if (a,b) exists then (b,a) is not allowed, also (a,a) for a
Bhai hindi me smjhi diya kro yl
Sir PLz...thora jldi videos Upload kia krein
hmara uni waly sir achy nhi hain.....ham aap se idhr hi parhaty hain..
Tomorrow is the test and I'm studying tonight ,🤫🤫🤫🤫
Yesterday was my test I'm studying today 🤫🤫🤫🤫
This explanation is illogical. How is something irreflexive because the numbers are not in the set when they are clearly in the set?
Same here plzz complete data structure playlist....🙏🙏🙏🙏
Arigato gozaimasu sensei
Bro said ir🔫🔫🔫reflexive
it is super fast for me 😭😭
Sir hindi me asani hoti😢😢
Lekhin Hindi asan nahi hoti 😅
خخخخخخخخخ انت بتقول اي
anti symmetric is not clearly explained makes no sense or logic
Let me explain you,
Antisymmetric = { (1,1) , (1,2) , (2,3) }
Here if 1,2 ( say a,b ) exists then 2,1 ( that is b,a ) is not allowed , however if 1,1 ( say a,a ) exists then 1,1 ( agai a,a ) is allowed
Assymetric = { (1,2) , (2,3) , (3,1) }
Here if (a,b) exists then (b,a) is not allowed, also (a,a) is not allowed
Consider a relation
R = { (1,1) , (1,2) , (3,1) , (1,3) }
Here R is not symmetric because ,R is symmetric if there exists a,b then there should be b,a since R contains 1,2 but not 2,1 R is not symmetric
However , R is also not Antisymmetric because , R is Antisymmetric if it contains a,b but not b,a ( note : it can have a,a as an ordered pair ) since in our example there exists 3,1 as well 1,3 which is not allowed in antisymmetric relation and
Hence,
Antisymmetric is not always equal to (not symmetric)
I hope you got it!
you shouldve had images to represent the relations in this video. all the formal notation is brain melting. no thanks
You talk too fast
Character In the video It's great, I like it a lot $$
So a=b means it is not symmetric but anti symmetric?
No you cannot because ,
Consider a relation
R = { (1,1) , (1,2) , (3,1) , (1,3) }
Here R is not symmetric because ,R is symmetric if there exists a,b then there should be b,a since R contains 1,2 but not 2,1 R is not symmetric
However , R is also not Antisymmetric because , R is Antisymmetric if it contains a,b but not b,a ( note : it can have a,a as an ordered pair ) since in our example there exists 3,1 as well 1,3 which is not allowed in antisymmetric relation and
