Mam ap ne symmetric relation m same same values ko symmetric kha h lkn directed graph m ap ne same values ky graph ko non symmetric kha h asea koii wo graph m bii to hum inhae symmetric khe sktae hain???
Same value reflexive k leya zaruri hoti ha jesy (a,a) ya (2,2) symmetric ma same same b hota ha lakin zaruri ya ha k agr same same k elwa koi ho to phr hm usy dekhy gy is ki main property ya ha k is ma opposite hota ha jesy agr relations ma (a,b ) ha to (b,a) bhe hona cahay (2,3) ha to ( 3,2) b hona cahay agr same same ha to wo b symmetric ho ga yaha graph ma dono symmetric ha mistake hoe ha dosra wala b symmetric ha agr is ma (1,1) (2,2 )(3,3 )or (4,3 )hota to hm katy k (4,3) ha or ( 3,4) nai ha to ya not symmetric ha
Ya relations ap ko questions ma diya ho gyn ya to ap ko restrictions ki ho gi k ap aesy relations bany js ma A/B jo hm ny question b kiya ya ya ap ko kaha ho k AxB kr k relations bany to phr ap ny A k first element ko B k ak ak element k sat pair bana ha phr A k second element ko b k ak ak element k sat is thra sb ko kr k pair bana ha aya ya to ap ny Khd sy banany han koi b
Equivalence relations wo hota ha js ma reflexive b ho symmetric b ho or transitive b ho to me ma ap ny dekha ha k is ma same same ha element han agr ha to ya reflexive ha phr symmetric k leya dekha ha k agr 1,2 ha to us ka opposite b ho ( 2,1 ) agr sb k opposite ha to wo symmetric b ha phr transitive k leya ap ny dekha ha k agr (1,2) ha to phr ap ny 2 sy atrt hony waha dekha ha agr( 2,3 ) ap to milta ya ha kch b 2 sy strt hony wala milta ha to phr ap ny phly waly ka first or dosry waly ka second wala pair dekah ha jssy ya pr( 1,3 ) to agr 1,3 b ha to ya transitive b ho ga agr ya 3no ha to wo relations equivalence relations ho ga

nice mam thanks for help in our study.
you are a Gem 💎
Great Lecture😁
Excellent Mam ❤
Mam 5:54 pe
(1,3) H to 1 Ka 3 ky sath relation m 1 aii g lkn ap ne 0 lagae Diya hh
G g you are right 1 ata ha thanks for correcting is ka mtlb k ap ko sai smj i ha 👍
mam midterm syllabus kitna hota ha mth202 ka koe bolta ha 18 lec or koe bolta ha 22 lec
Mam lecture 13 my 7:28 pr ap ny set A pr jo relation banaye hn ..upr bhi bht sy question my banaye hn ...to wo khud banany hoty hn?????
Ya relations ap ko questions ma diya ho gyn ya to ap ko restrictions ki ho gi k ap aesy relations bany js ma A/B jo hm ny question b kiya ya ya ap ko kaha ho k AxB kr k relations bany to phr ap ny A k first element ko B k ak ak element k sat pair bana ha phr A k second element ko b k ak ak element k sat is thra sb ko kr k pair bana ha aya ya to ap ny Khd sy banany han koi b
Màm 13:50 pr smjh nhiii aii h??
Equivalence relations wo hota ha js ma reflexive b ho symmetric b ho or transitive b ho to me ma ap ny dekha ha k is ma same same ha element han agr ha to ya reflexive ha phr symmetric k leya dekha ha k agr 1,2 ha to us ka opposite b ho ( 2,1 ) agr sb k opposite ha to wo symmetric b ha phr transitive k leya ap ny dekha ha k agr (1,2) ha to phr ap ny 2 sy atrt hony waha dekha ha agr( 2,3 ) ap to milta ya ha kch b 2 sy strt hony wala milta ha to phr ap ny phly waly ka first or dosry waly ka second wala pair dekah ha jssy ya pr( 1,3 ) to agr 1,3 b ha to ya transitive b ho ga agr ya 3no ha to wo relations equivalence relations ho ga
