Completely agreed sir, typing mathematical equation in PPT is tough task, hats off to your dedication sir, it's up to we students who must utilize your videos 💯
Sir you helped me in all the three semesters.. Now it is the last engineering mathematics.. So I am requesting.. Sir please make videos on "optimization and calculus of variations".
Sir you explain so easily ... it feels so easy after you teach ....thank u sir...You are a very good teacher I have met in real life.. Thank u so much sir .....

Theorem 3 (a) can be done by this easy way we know aa^-1 =e a^-1=e/a let b = a^-1 bb^-1 = e b^-1=e/b b^-1=e/a^-1 b^-1=e * 1/a^-1 b^-1=e * a/e b^-1=a (b = a^-1) (a^-1)^1 = a same can be done for binary operation of addition 😀
Sir jo apne ppt pe smjaya hai algebra class me apko btana chahta hu ki me Hindi medium ka student hu ... Mere ko English nhi ati thi but apke ppt p smjane ki vjh se mere ko ab English smj me ane lg gyi hai .. ab word p bhi pakad ho rhi hai sir thanks for this cantant Again thank you so much sir ji ❤️
Yetna kharb kaise koi paara skta hai Sir aap ye casual me chizko smjhate hai aaisa lgta hai ham loog ko sab aata hai es tarh se aap explain kr rhe hai yetna short me
Anyone please clarify my doubt.........why do we write. (a*b)^(-1)={(b)^(-1)}*{(a)^(-1)}. Why don't we write (a*b)^(-1)={(a)^(-1)}*{(b)^(-1)}........i also think that each and every group is an abelian group......please clarify
Thanks very much sir. Great content, detailed explanation. these linear and abstract algebra classes can be well understood and proves quite helpful for my semester exams. Looking forward to more such amazing videos
Nice explaination.....I rarely subscribe someone channel......now I subscribe ur channel.....the way u r teaching is awesome..... But I request u to speak a Little bit slower ... specially in tough questions thanks
Sir plz tell me that ..what the relation of distributive AG groupiod with different sub clasesss of group... Exa: with semi group,monoid,medial ,paramedial,qiasigroup etc

Can you make videos on 2d geometry pls sir
Sir aap bhut acccha pdate hai aur aap ese he pdaye
Sir Heartful thanks for ur videos
Can u send that notes as pdf sir
Sir ...Group me distribution property kaha lagta hai?? Distribution ke bare me kuch nehi likha hai Aisa kyu??
Completely agreed sir, typing mathematical equation in PPT is tough task, hats off to your dedication sir, it's up to we students who must utilize your videos 💯
Good explanation of a difficult concept in an easy way. Thank you so much for your efforts
It's really true.
Sir your way of teaching is fast try to teach to the concept level.
No need for concept level do you have to do PhD or masters?
Sir you helped me in all the three semesters.. Now it is the last engineering mathematics..
So I am requesting..
Sir please make videos on "optimization and calculus of variations".
Sir please cyclic,cosets, quotient and permutations and homomorphism groups upload karie.
Haan 😢😢
It is confusing when you write * in place of multiply sign (×) because * represent the binary operator (+, -, ÷, ×) .
Bahut umda video hai sir🔥
Aane wale time mein is video se logon ko bahut help milegi✨
Gurudev ..
Aap group theory ,ring theory and linear algebra ...
RUclips pr complete pdaoge kya...
Pls sir jrur btana...
Yes but it will take time
Ok gurudev..
Aapse request🙏🙏🙏 h ki daily km se km 2 vedio upload kr do...🙏
Daily 2 Videos???
Guru Ji ko Saans toh lene doh!
Kitna Tangg karoge ap??
Thank You for free from laborer work.
Please sir group theory ka all topics upload kariye
Thank you Thank you so much sir mujhe ye college me samajh nahi aa raha tha but aap aisa batate hai ki samajh aa jata hai . Thank you so much sir
Sir per day vedio upload kreye, paper ane wale h. 🙏
Sir you explain so easily ... it feels so easy after you teach ....thank u sir...You are a very good teacher I have met in real life.. Thank u so much sir .....
Group pdhne se dr lg rha tha
Ab 3 video dekha h inshaallah puri playlist complete krungi
Thank you sir
Sir cancellation property nahi bataya apne 😢
Sir .. yahi tarika best hai padaane ka.. math ko..
Sir aapke teaching se maths bhut bhut easy lagta hai
Thanks sir
Sir your teaching style is just amazing and lucid....it's very helpful for those students who are financially weak ❤️❤️
Sir group theory k sary topic krwayen......plzzzzz
Awesome and very nice video Sir 👌👌👌👍👍👍
Sir, at 20:05 in the video :- In the question we have been given ax=b, then how can we say ax=a?
Sir Please Make Vidoes on Bsc 1st year Geometry 2d ,3d plane and straight lines
Kis University me pdte ho?
Bsc 2nd year ki koi book aati he kya jisme pura samjhaya gaya he har question koo????
sir pls make a video on special linear group and general linear group
Thank u sir.😊😊 Finally ye concepts mujhe smjh AA rhe h
Good explanation thanks sir

REALLY APPERICIABLE WORK DONE SIR JI HATS OFF TO U, U PEDAGOGICAL STYLE IS UNIQUE
Thank you sir to clear my doubts
Thank you so much 🙏🙏
sir video is great but at last it become confusing so plzz try to explain with examples or some different way but over all concept is understandable
Well explained sir
sir apko national teacher bnaa dena chahiye :p.. Thanks alot sir.. your content is helping number of students like me!!
Yeah you right
Sir please make video
property of order of elements and group.
🙏🙏🙏🙏🙏🙏🙏🙏🏼
Lots of tnk sir
Sir plx first lecture konsa h group ka
Thanks so much sir g🙏
thanks a ton sir
Amazing sir
Theorem 3
(a) can be done by this easy way
we know
aa^-1 =e
a^-1=e/a
let b = a^-1
bb^-1 = e
b^-1=e/b
b^-1=e/a^-1
b^-1=e * 1/a^-1
b^-1=e * a/e
b^-1=a (b = a^-1)
(a^-1)^1 = a
same can be done for binary operation of addition 😀
Sir permutation ki bhe videos bna do please sir
Thank you sir
🎉🎉🎉 Thanks 👍👍
Sir ek non abelian group ka video upload Kar dijie
17:42 yrrr koi simple se bat nhii hai...😂😂😂😍 Contradict....
thanks alot sir

Tq sir.🙏❣️
Sir.. in proving the uniqueness of identity theorem how can you say that e*e'=e'*e? Because given group is not necessarily abelian group..
hello, please you have a mistake in 21:34 (since e1 is right not eight ) Sorry for the inconvenience
