Your approach of linking theory with previous year questions is really appreciable sir!!! ...very effective and helpful video for especially beginners...it gives a moral boost up...Thank u very much sir!!

[tanusreedas]

Thank u sir concept bohot easily samajh main ata hai ap jab samjhate hai to thank u very much

[Pankajkumar-ghsu]

Mene bahut se you tube channel dekeh h लेकिन आपके जैसा तरिका और कटेंट नॉलेज और पढाने का लाजवाब तरिका मेने कहीं नहीं देखा

[MathGenius]

I like your opinion and your concept .. Thank you sir . I watch your video all

[priyankabr]

One of the best youtube channel for beginners like me to prepare for csirnet it is very easy and simple to understand the concepts and the way your explaination is carried on and this helps us to solve the question on our own thank you so much sir.

[kajalghosh]

Sir, apnar explanation process khobee valo....thankyou very much sir....

[kothiyaamin]

we know that subset of a countable set is countable. Suppose f is a function with domain A and
co domain B.
By a property of one or onto functions,
If f is one one the A is subset of B and if f is onto the B is subset of A.
clearly when f is one one with A = S and B = N the S is subset of N and hence S is countable.
If f is onto with A = N and B = S the
again S is subset of N and hence S is again
so options 1 and 4 are correct and 2 and 3 are in general incorrect

Kai bat nhi sir jitna time lagta hey lagne de hume concept chahihe

[Pankajkumar-ghsu]

Sir aap bahut bahut bahut achaa kr rhee ho

[sajadparray]

Thanks sir, so nice explanation as usual ... Really helpful

[sunilrampuria]

I don't think that one should specifically study cases for countable and uncountable sets. We just need to know that the cardinality of uncountable set is greater than countable set and the following: If there exist an injection from A to B, then |A| ≤ |B|, and if there exist a surjection from A to B, then |A| ≥ |B|.

आप हर क्युसन की गहराई तक जाते है ।
आपको शायद नही पता होगा लेकिन आपके एक सवाल के पीछे बहुत से कसेंप्ट क्लियर हो जाते है

[akshaydarji]

Any infinite set is similar to at least one of it's proper subset?
How to example?
Please help sir.

[NeerajKumar-dine]

Sir appki har video concept base hoti aa 😊 u r great sir

[komalgarg]

Great sir very helpful and because of Ur explanation ...real analysis me interest aane laga h

[suryapriya]

U r explaining in a perfect way... Its very useful ...pls follow the concepts in question... Don bother about people comments who ask for only answer key

[Pankajkumar-ghsu]

आप टाइम लेते हो लेकिन उस टाइम के बदले आप इतना दे देते हो जितना हम 3 से 5 घंटे की क्लास मे नही ले पात़े

[positivevibes]

You r a great teacher sir...
Sir kya real analysis for csir net k liye apki all videos sufficient hai...bcoz there is time shortage....bcoz of ur motivational videos I started preparing net for this Nov..
So plz sir guide for real analysis

[PPSCAndFPSCMATHCENTER]

I'm agree with ur method of teaching I need it...Pls keep it up

[yogendravishwakarma]

Bahut acha concept explain Kiya sir aapne.. sir please make a video how to approach the problems of CSIR net exam.
