Open Disk, Closed Disk, Annulus, Neighbourhood & Deleted Neighbourhood of a point : topology part-1 

There is something beyond learning, actually I enjoyed the mathematical meaning of these concepts.Teaching is an art and your a really good artist.

I have never come across this type of lectureship skill before in my clg. Thank u sir. Very impressive.

A true teacher who doesn't just impart knowledge but makes us "feel" it👏

Sir never be Demotivate one day you are the most visited RU-vid for higher mathematics....

Sir apka bhi koi jwab nhi, Amazing Teaching Skill, Ye banda apko tah dil se salute krta h❤️❤️❤️🙏🙏🙏🙏🙏

Sir thanks my PhD mam was unable to give us concepts but u are a magician. Thank you very much

Sir, your way of teaching is very commendable and your lectures are clearing a lot of concepts.I am referring your lectures for brushing up my concepts for GATE and i have generally seen educators focusing on problem solving not on concepts. Please include keywords like "GATE" "Engineering" so that more gate aspirants can see your lectures appearing on search screen.

You are the best teacher in RU-vid for higher mathematics..... 🥰 love ❤from ofisha

I searched a lot for complex analysis for bsc engineering, but nothing seemed easy to me, this is the only video that taught the foundation of complex analysis . Thank you sir .

15:48 sir it's not deep but this is THE BEST way to teach ❤❤

Thanks for cleared my all doubts 🙏🙏🙏💯

The equation for Deleted Neighbourhood is i think a bit unsatisfactory. Because in my opinion there should come Zo instead of 0 in the equation i.e. Zo < |Z - Zo| < delta. Isn't it???

Sir Apne metric space ki videos B'nai h???

Superb 👌

Brilliant video.Thankyou.

Nice explanation sir.

really helpful. to me you are the best

Thanks for removing my confusion abuot

Sir I request you make vedio also on linear algebra please.
