Mam Dn is group of symmtry on regular polygon. D2 two side ke regular polygon per symmtry ka group But 2 side ka regular polygon hota to nhi? To hm kaise bol payenge ki D2 is isomorphic with K4
I think you cannot say no. of elements of order d where d|n = phi(d) for non cyclic group. But eventually Z(n/2) is isomorphic to a subgroup Dn (Rotation). And Z(n/2) is cyclic so your claim could work.
Mam...first you told that all Dn is cyclic and then later u told that D3 is noncyclic ... vut in accord to me when we apply rotation and then reflection i.e rf in D3 generate the whole group so it is cyclic ..make me clear if i m wrong
Try to find Inverse of elements....those elements which are self invertible those are of order 2 Secondly see If we operate any elements 2 times and we get identity...then order of that element is 2
Very nice elaboration ma'am ,Thanks a lot
majja aa gaya lecture mein.
Very well explained... Thanks a lot... but at 21:40 you mentioned D_n is cyclic. I think its only when n
Very nice mam
Bahut achhe se samjh aaya ma'am

Nice miss....basic khup chan sangata madam... confidence vadato ..all basic sangata .. thank you....

Many thanks 🙏
Mam bahut acha class tha ❤️❤️❤️
Just wow
Awesome Mam .
plz Keep it up.and plz Upload more videos about Rings and Vector spaces .
👍👍👍👍👍👍👍
Mam so nice
Thank you madam..

Very very very very very thanku mam....
Thank you 😊🙏
Mam Dn is group of symmtry on regular polygon.
D2 two side ke regular polygon per symmtry ka group
But 2 side ka regular polygon hota to nhi?
To hm kaise bol payenge ki D2 is isomorphic with K4
Ma'am please upload a video of no elements of order in D10 group
Maim aap bahut accha padhati ho..☺️
🙏
Thank u mam.❤
Keep watching
Dn group is exists for all n≥3, but how you get D2 ????
Super Class
Thank you very much madam

Apka aur viedo nhi mil rha h
Mera viva h plz duwa kryee ga .......i am from Pakistan
All the best ☺️

Dn is not cyclic
Pls mam I can't understand no.of elements of order 2
Try to find Inverse of elements....those elements which are self invertible those are of order 2
Secondly see
If we operate any elements 2 times and we get identity...then order of that element is 2

Mam D16 mai 16 order ka element hoga ?
If D16~Dn
