Please help me. To prove lim(sinx/x), we need to prove it through sine series which is dependent on Maclaurin Series which is dependent on derivative of sin x which is dependent on lim(sinx/x). Then it's a cyclic way. Which is the fundamental theorem and how to prove it without depending on daughter theorems.

Example: (1,2),[2,3),[3,5] Sets are together Cover of a set S=(2,4) Because union of those 3 sets contains all points of S.

One of the best teacher I've ever seen! He's so fast, but he makes every topic so easy! Thank you so much sir! (From Bangladesh)
🙏धन्यवाद सर आपकी क्लास लगातार दो साल से ले रहा हूँ।आप बहुत अच्छा पढाते है।🙏
Not understandable just reading what's written
Super sir you are role model for young Mathematics students sir 🙏
Best teaching ... Sir thank you so much
Sir your videos are genuinely helpful for us. They clearly explain everything in a short period.👍 thumbs up sir
Sir thank you so much... Best real analysis class
Ye bahut useful hai sir
Full of knowledgeable video sir....🙏🙏🙏
Thanku very much sir for providing us that much quality education 👌
Million Of thanks sir
Great sir ji 🙏🙏
THANKU so much 😍 Sir🙏
M 1to Msc final tk k study m apke jaise sir mujhe mil nhi isliye m bhut dukh ho rh h nhi to aj m aur achha hot love you sir
Thanks a lot sir❤❤❤
Sir very good teaching
Thnx soo much sir really you make it soo easy sir 🙏🙏🙏🙏
no deep explanation, easily pass the goal !!!
Means?
Sir ....can you please upload the videos of vector calculus.
sir jo ye aap pdha rhe ho inka pdf mil jaye to bhut benifit hoga..plzz sir if you can provide then do it sir ....its a humble request.
Clear hai
thanks alot sir
Thank you sir
Riemann integration per video uploaded Keejiye
Thanks sir🙏
Sir real Analysis pr aur video bnaiye
Sir sets ka real life practical me kya use hai????
Thanks sir😍
Sir plz continuity and diffrantibility aur rimen integral pr b classes lao
Sir ye topology kalian b same hain?
Sir Mertens theorem ka vedio upload kar da
Nice👍
Sir Heine borel theorem meto aapke conversely bhi proof krna tha... Yeto aadhi hui bs.... Compact lekr closed nd bounded bhito proof krna tha... If I'm not wrong????
👌👌👌😊
What about interval I1.
Thanks

then prove it by first principle.
Use squeeze theorem to prove it.
As -1 1
Divide by x
-1/x 1/x
As lim -1/x = lim 1/x = 0
This implies lim sinx/x=0
You can prove geometrically
Sir please reduce the price of unacademy subscription. I want to join
Sir namaste I am student of master level i need your suport in mathmatical analysis in med level please upload the vedios related topic
Thanks sir
Thank you sir
Sir[a,b] hi kyo maan ke chale h reason to bataye. 😊
Sir phle aap likh k padate the tb jyada achha smj aata tha 😔😔
Pichli videos sari samajh aayi but ye hein borel theorem samajh nhi aayi 🤒
Hai na.. 😁 😁 😁
💯💯
Kya koi bta skta h sir open cover or sub cover kisko bol rhe h

There are so many wrong explanation in the proof.
SMJHAYA CLEARLY NAHI HAI

The worst teacher even just translations what written in english to hindi lmao all these bot comments are praising him
Than pay coaching fee why you here??
