I went to many institutions and invested a lot of money 💵 but no one ☝️ taught like you …..and you taught so very well 👌 without any fees thank you so much dear sir ❤
8:17 I have a doubt in selection of option c. We neglect [-1,1] because 0 belongs to it. Similarly option C also have 0. Then why we take as a correct answer?.... Please someone explain me 😢
The given option is set not interval because 1/n, n€N given .. So we need to find the function corresponding to this set and then check it continuity.... For example, for a and b option, function is given , but for c and d , function is not defined.... That's why, first defined the function and then check... Hope it help you.
Thank you sir🙏 Sir at 43:04 image of close interval under countinous function is always closed. and range of tan ^-1x is -pi/2 to pi/2 . So how option 1 is incorrect
@@Siyagupta52 ha to in this case you take A=R which is not closed But continuous function always map closed to closed Compact to compact Cauchy to cauchy So option 1 is true here

Forget wrong things only take right and good things.

@@aakashbhuse3170 absolutely 💯 right brother
@Dr.Harish garg , at 1:16:37 csir net June 2019 . Sir In this problem options (c) and (d) are also correct.
Aisa content aaj tak nhi mila you tube pe... difficult topic hai isko banane ke liye bhot thankyou sir... kindly make topicwise aptitude pyq
very helpful sir `thankyou so much sir .
Superb session.....❤
Thankuuu so much sir.your teaching style is excellent.❤❤❤❤❤❤❤kash ap hmee phle
Very helpful sir . Please upload more videos.
Really, you are teaching Real analysis, sir; thank you so much for sharing such videos.
Very helpful ❤
Bahut jyada helpful h sir ji
Tku sir
Your videos very use full sir
My prayers and wishes are always for you sir 🙏
Sir this is very helpful please upload next 2 lecture very soon please your trick very helpful in exam
Very nice lecture sir....
Very nice explanation, thanks sir
Thank you so much sir ❤
Thanks alot Sir 🙏
Thanks again ❤
Thank you for your efforts sir 🙏
Really you are great sir ❤
Thank you sir 🙏
Thanks sir...❤
Thanks you sir aap great ho
Thank you❤ sir
at 35:40 how did we have discarded the unbounded option(d) .Please provide a valid justification for the same
1/1+e^x is cts, one one and bdd.
Take tan inverse x as example
solid content sir
Very helpful 🎉🎉🎉
Thanks a lot sir jee .
How to take f(x)=1, it is not one one ..at 35:01
You are genius sir
@ dr harishgarg 41:00...a option kaise shi ho gya ...f(a ) bdd to a ko bdd kaise bol skte h ..inverse image thode hi bdd hoti h
Thanku sir❤
thanks sir
love you sir❤❤❤
Thank you sir
Thanks sir ji
Thankyou sir
sir 44 min, option D is wrong. let f:(0,1) to R given by f(x)=1/x , then A=(0,1) is bounded but f(A)=(1, inf) is unbounded
Thanku sir
37:10 how can we consider A=R in the (4) option sinceR is not compact
A={1} it is compact , f^-1({1})=R it is not compact
Thankyou

Sir at 43:04 image of close interval under countinous function is always closed. and range of tan ^-1x is -pi/2 to pi/2 . So how option 1 is incorrect
Take f(x)=e^x , A=R then f(A)=(0,oo) which is not closed
@@Siyagupta52 ha to in this case you take A=R which is not closed
But continuous function always map closed to closed
Compact to compact
Cauchy to cauchy
So option 1 is true here
@@shefalithakur4580continuous function maps compact to compact
Closed to closed is not true .
As take the same example of e^x
@@Siyagupta52
I got it dear thanks
Continuous not necessarily map closed to closed
Continuity maps Closed inteval to closed interval...but not closed set to closed ..ie ex R
sir 70min, lim x tends to zero [x] is not defined, so [x].sin(1/x) cannot be continuos at 0.
Sir please upload the vedios of linear algebra ... inner product spaces...and orthogonal...invariant subspcaes...
Linear algebra, inner product space etc already uploaded.. Explore at my youtube channel.
@@DrHarishGarg ok sir thanku
at 16:11 how opt d is correct?
Please explain in bilingual. Your lecture is very useful for me. Thanks sir
Please complete this topic with uniform continuity and all
Already uploaded.... See at my youtube channel.
37:24 can anyone tell me..why sir had not taken compact subset A...why he has taken A=R
Yes A can't take R because A is compact
34:24 you have not taking example f(x)=1 because one one function bola ha😢
@50:14 option (d) is incorrect as compact set will map to compact set.
Is this correct or not?
Can someone confirm?
Sir ode or pde bhi topicwise krwa do
sir last request..... please upload a video on pyqs of ring theory.... 🙏🙏
Please upload the next lecture,
Sir... Please... Which software you are using for screen recording this video ?
31:37 b option me continuous booa ha but greatest integer function always discontinuous at countable numbe of points how b option correct 😂
🎉❤
At 7:50, c is not correct
