[@birendrakumarsingh2148]

21:10 we can also show that this is not a transitive relation by the following example . Lets say a is chacha ka ladka, b is me and c is chacha ki ladki . So a is a cousin of b and b is a cousin of c but a is not the cousin of c but a is the brother of c . Hence , it is not transitive .

[@JNVMVEDANT]

Best teacher ever and forever. Sir's smile is cute ❤️❤️❤️❤️.

[@pratisthabhattacharjeexiie6612]

1:14:09 epic style of laughter😂😂😂 (listen at 1.75x/2x or 0.25x)

[@Ria-tw6qq]

😂😂😂😂😂🤣🤣 oh my goddd😂😂😂

[@shraj340]

21:00 one more case to prove it's not transitive... When C is A 's sibling then a is not cousine of c he is his/her sibling

[@Ck-fk9fd]

Creativity 100 level at mahabharat and Ramayan part

[@arvind4424]

(A)- yes (B)- no (C) -yes (D)- no Love you and and your style of teaching❤️❤️❤️❤️❤️❤️❤️

[@shreyamishra7126]

Best faculty of MATHS ever and forever in youtube🙏🙏

[@hiiby5530]

Doubt at 34:25 By taking values of a=3, b=2 ,c=1 , transitive is possible

[@karnikasingh4166]

Aur bhi aisi values hogi jisse transitive possible hoga but disprove karne ke liye sirf ek hi counter example chahiye .....

[@SaketDubey-kp4ky]

Finally after searching a lot of videos founded a best lecture ❤❤❤❤

[@Nitukumari-pv9jj]

[@mamtamaa6994]

Function homework question (a) yes. (b) no. (c)yes. (d)no

[@khushiagrahari7947]

Sir ur smile Is sooo cute❤️❤️😘....and u explained this very easily 👍

[@VERMAJI-jf5fl]

Hello

[@banothdevsingh7680]

We cannot forget nishanth vora sir .. along as mahabharat and Ramayan is known to people@......... u watched this session

[@ashishsharma-xp9ih]

Sir if we put a=1 b=2 and C=3 then it is transsitive in 35.47 sec

[@Justme_real]

35:38 ye waale main agar a=1and b=2 and c=3 rakhe to transitive ha jayega na

[@bhumikaagarwal7159]

6:02 lecture start

[@pratikkumar2951]

Sir you are clearing all my Doughts. Thank you so much😊😊

[@armanbansal9001]

Sir in 3rd question a is divisible by b and if we take c as greater then 4 then a is not divisble by c and thus the fuction is not transative

[@ARIF_SHAIKH]

21:25 i think yess... because riste jan pehchan se ni hote riste to bnte h khud bas jan pehchan krna jaroori hote h.. Gang of wassipur se motivated hu 😀

[@Birendra887]

5:55

[@DevSharma-no1gl]

Please can any one tell that the type of question sir is doing on 34:00 how to know about numbers we have to take to check transitive🙏🙏🙏🙏

[@mahaksoni6880]

34:40 agar hum a=1 b=2 c=3 put kre to ye transtive relation ho skta h ....

[@mahaksoni6880]

@shrujai Kumar lekin ab Merko ye clear ho gaya h ... Hme saari conditions check krni pdegi agar ek condition bhi satisfy nhi hoti h to vo non transitive hoga ...

[@vinisha.7248]

[@ut6582]

32:00, sir, in the question a and b are real numbers, and the value u took for b an c, aren’t. Also, if you take 1,2,3 the transitive property is correct.

[@ut6582]

@Rishabh yadav Jee 2022 wdym “No”

[@ut6582]

@Rishabh yadav Jee 2022 ain’t no one asked for ur opinion

[@umeshgupta5526]

Sir 35 min.12sec par aapne usko transitive nahi hai aisa aapne prove kiya toh aapne transitive hone ke liye different example se prove karne ko kha hai toh kya aaise questions mein examiner jo hoga woh done ko sahi kar dega agar example waisa de

[@prabhatsati4387]

Haa

[@karnikasingh4166]

Transitive hone ke liye example se prove ni karna hai , aise to kitne sare numbers hai ......'if 'wali condition to let karna hai aur 'then' ko prove karna hai

[@vishaldhote]

Some specific input we can use that called domain

[@likhitaallada4300]

[@harshjha536]

Sir in 24 minutes homework question ka answer m reflexive nahi hoga shayad because a can zero also thus a/a equals 0/0 which is not defined thus this will not reflexive !! May I correct???

[@bikramaditya8316]
