Thanks to create interest in real analysis.i m also msc maths.i watch your lecture it's really good .and for other it produce zeal to understands real analysis

Thank you ma'am explaining so simple and easy everyone can understand.

[@vittuyadav840]

You are perfect teacher for mathematics ma'am

[@akashab1111]

At 7:10 I think it will be a∈R in place of a∈S because it's not necessary that limit point lies in S.

[@rhythmahuja7816]

You make things so simple :)

[@akashgomes1113]

Despite having good progress in group theory, I'm struggling to remember and prove the theorems in real analysis. How can I recover it?

Mam kya ye term structure and length of open and closed set me b use hosatkti hai.

[@parthmehta13]

What should we understand from a topology on a set? Does it have any more information for a set besides the mathematical structure for a set? Does it have a physical significance or it is an abstract concept only?

[@tripBohemia]

It has great significance in life. But not directly. As 24 carat gold can't be used directly so are these abstract concepts, they can be used in practical life by mixing some Cadmium or copper like things only.

Ma'am Set A={1,2,3,4} agar isko limit point waali definition se dekhein to ye to closed Nahi ayega because it does not contain all its limit points infact it doesn't have any limit points. Please clarify this doubt

[@tripBohemia]

A = {1,2,3,4 } Then A'= { } = ∅ = Nullset (ie. The derive set is empty) Clearly A'⊂ A (ie. The derive set of A is contained in the set A) Hence A is closed.

Mam ye theorem prove Karke do exam me jyada theorm ate hai university

[@vickeykooper2674]

Mam, closed set mey limit points hote hai, aur limit points se matlab yeh hai ki uske jitne bhi neighbourhoods hai unmey se some elements other than concerned point maujood hone chahiye. Phir {1,2,3,4,5} set kaise closed set ho gaya, haalaaki uska complement open set hai? Please e doubt clear kar dijiye.

[@tripBohemia]

Set of limit points of {1,2,3,4,5 } is an empty set. A set is closed if it contains all its limit points i.e. A set is closed if the set of all limit points of the set is a subset of the set. Here the set of limit points of {1,2, 3, 4, 5 } is null set which is a subset of every set. Thus {1, 2, 3, 4, 5 } is closed.

2. Which one of the following is true! (a) null set is an open set (c) null set is a closed set (b) null set is semi open set (d) none of these.?

Null set is a clopen set. It is both open and closed.

Aapne bataya tha ki S' subset of S then S is closed but natural no.s ke case me aisa nhi ho rha then how set of naturals is closed

[@tripBohemia]

Naturals k case me b Aisa hi h. N'= {} = Null Set And hence N' is a subset of N

[@mahimagupta5985]

Mam ,are all open interval closed set ? Bcz they contains all the limit points.please clear my doubt

[@sharndeepkaur5628]

No,open intervals are not closed sets,as explained above that for a closed set derived set S' must be a subset of S,but in case of open sets for example(2,4).no doubt it's all points are limit points ,but its derived set is[2,3] and you know [2,3] is not a subset of (2,3). I hope it will clear your doubt .I just think it will may be answer of your question........😊
