Definition of Open set
infinite intersection of open sets need not to be open
Union of two NBDS is NBD
Intersection of NBDS is NBD
Superset of a NBD is also a NBD
Every Open interval (a,b) is neighbourhood of each of its points.
Closed interval is neighbourhood of each point except end points.
real numbers is NBD of each real number
Rational numbers set is not the neighbourhood of any of its points.

Ma'am aapka channel future me Jake bohot bodha channel bon jayaga bohot atse se samjhate ho ap thanks ma'am ❣️
Thanks for appreciation…. Please write your valuable reviews at g.page/r/CRP90Pt3uFhFEAg/review
please like,share and subscribe.
had one doubt, mam pls explain why u took the difference between Xn and point l (which is the limit point ) or Xm and l €/2 instead of just €
Mam u have amazing explanation skill 😊
Thank you 🙏
Please share the link of every cauchy sequence is always convergent
Mem agar puche real convergent sequence is cauchys sequence than is me kya changes karna honge
Thanku mam for this amazing lecture

Thank mam
😊
Thnx ma'am ji
show that every convergent sequence in a normal linear space is a cauchy sequence pleas explain
Mam is theorems converse is not true? Aur koi counter example?
Mam cauch sequence main hm [Sn] la sakta Hain ya ni
Nicely explained Thank you so much mam but your videoes are not organised.
Thanks for my all confused loss madam
It's my pleasure 😊

Ma'am caughy convergence criterion theorem ka link share kr den
Mam m⁰ kya he
Thank you mem 💝

नमस्ते mam 🙏 , मुझे n०€N me n० क्या है वो पता नही चला ठीक से
Nice
Thanks 😊
€\2 q Lia jb k hm sirf sequence mn € lety h
€/2 liya because hame last mein € Chahiye jab hum add karte hai to € value mil jati hai you can take € then you will get 2€ at the end you can say 2€=€^’ that will also right
Mam g xm big h ya xn
Xn and Xm mein se koi bhi big ho sakti hai because we are using modulus and the value will be positive.
