Unlocking The Secrets Of Complex Analysis: Power Series & ROC

[@annuvats786]

sbse favourite. Lecture series Unlocking 🔐 Secrets 🎉 ♥️🎁♾️☘️ Thank you Sir 🙇

[@sameershaikh-k9z]

What a lecture sir 😍 kya padhate ho aap 👍 itni Acchi explanation Power series jo ki sb bolte hain chota sa topic hai usko bhi aapne ittnaaa explain kr diya❤ Power series me hmko sirf ROC hi pta thi 😢 itne concept to miss the mere tbhi questions proper solve nhi hote the Thank you so much sir 🙏❤

Ans 6). a,c are true .

[@shamita4015]

Sir lecture is nice

[@sumanchattopadhyay4042]

Sir ager kisi function open unit disk pe analytic ho and singularity 1 par ho aur ager hum z=-2 ke around power series open kare to uska Roc kya hoga....iss concept ko thoda samjha dijiye

[@SBTechMath]

distance between centre and nearest singularity to the centre

[@priyankachoudhary8911]

Sir q 6 ka first option not correct bcz hm koyi aesi seq lele jiska sup|an|^1/n wo 2 ho to radius of cgt 1/2 hoga ,,or second bhi incorrect hoga example an=1. ,3rd correct hai bcz nth Power ka Jo cofficiente wo n+1 hai to ROC wo bhi 0ne aayega

[@priyankachoudhary8911]

Sir 4th bhi ni hoga bcz non 0 finite roc ke liye boundary ke kuchh aese point bhi milte hai jahan f(z)cgt ni hoga

[@priyankachoudhary8911]

Sir 1 option kese true hoga???

[@SBTechMath]

beta sab kuch kuch example se hi kroge to phir aap questions ko nahi smjh paoge. aap bas conditions dekh kr example set kroge and it will lead you to some wrong practices.

[@dikshashukla855]

Aap an ko bounded lelo k se, then an+1/an krke dekho 1 ajayega​@@priyankachoudhary8911

Sir 42:31 sir ek function ko represent krne k liye Kai series ho skti h?

[@SBTechMath]

Definitely yes. It depends on “about which point”

@ course has been started. It’s available on app. Link- bit.ly/net2025

[@meghagupta1314]

Sir kya boundary for non isolated singularity ho sakti hai and if no,why ?

[@SBTechMath]

Yes

[@meghagupta1314]

Sir agar boundary par only non isolated singularity ho tohh hum function ki boundedness ke bare mein kya bolege domain ke andar ??

[@SBTechMath]

@meghagupta1314 boundary par singularity pole ya essential hai tab function unbounded hi hoga

[@creative_art_work]

In question no. 5 , how can we write a_n =0 when n=odd

[@SBTechMath]

open the series an check. I have taken out z. Remember this thing also.

[@komalkapoor3488]

Sir iss ques ka ans a hai only.?

[@SBTechMath]

a,c

​@@SBTechMathsir for option a) if an= 2+(-1)^n.......then it defines analytic fnx on |z|

[@SBTechMath]

@@14-nasirhusain83really? Apne an ki hi limit calculate kr li hai. But ROC ke liye Apko |an|^1/n ki limit find krni hai and that is 1. So option a is verified
