I am a student of 11th and i have not attended limit and derivative classes in my coaching and this video helped me too much for my study.Thank you so much mam.

[GulshanKumar-totd]

Normal: Watching before 11th exams
Legends: Watching after 11th exams for clarification of concepts for 12th

[NaturalNandini]

She joined 10 years ago in 2011 and is teaching till now! Hats off to the hard work

[chilagodunithyananda]

For Chemistry - Pankaj sir
For Mathematics - Dear sir
For Physics - Alakh sir
For those👆 three - *Roshni Mam*

[ashutoshmehndiratta]

Thanks alot
I'm 52 yrs old well settled Engineer.

These all points vanished away from mind. Now I could recall my golden old school days.

Very interesting. Thanks 🙏🙏

Almost every one is taking about how he didn't studied in class 11th and

Here: I am who is trying to understand in graduation. ...😂

Video is very appreciative its just covered all the important concepts in this one video
That is great

[abhishekpathak]

Mam aap hamare lie kitni mehnat karti ho. I understand esi vedio banane main kitna time lagta hai aur mehnat bhi.
Hats of to you Mam.

[sumitverma]

We r the one who has not studied a single topic of this chapter in class 11th and now coming here to clear the concepts for class 12.
Conclusion - 11th valo ache se pad lena tabhi 12th m samjh aega.
Thnku so much mam ❤️. Love youuu

[anishamalan]

All the best✊🖐️🖖🤘🤙 everyone for their final exams may 👌u all passs 🖖with 50+ 🤙Dil❤️ sa duaa h 😭🙏

Ma'am I think there is a substitution error at 1:09:18 ... while explaining the derivation of f(x) = sin(x)
in the formula sinA - sinB = 2 cos(a+b)/2 * sin(a-b)/2
You put "a+b" = x+h
But as 'a' = x+h and 'b' = x it'd be actually substituted as "a+b" = x+h+x
So the expression should be evaluated as follows...
( 2cos([x+h+x]/2) * sin([x+h-x]/2) ) / h
= 2 cos([2x+h]/2) * sin(h/2) / h
= 2 cos(x+h) * sin(h/2) / h ... (2-2 got cancled)
= cos(x+h) * sin(h/2) / (h/2) ... (As per madam's method putting the 2 of numerator at denominator
= cos(x+h) * 1
= cos(x+0)
= cosx

Please tell me if I'm doing any mistake in this.
And... Thank you for the amazingly simple made explainations madam. I'm so grateful for this to you 🙏😊

Tomorrow is my exam and today I touched the textbook for the first time, can't believe that 10th standard 93.2 % holder like me is trying to get passing marks Tomorrow 🤣😂🤣🤣🤣😭

[IA-vvuv]

by this we can realise the power of human being
we study the whole year to complete course
and the bank benchers complete it in 2 days

[ishitaagrawal]

I got 95 marks in 10thboards and only 37/80 in 11th and now i am trying to study this chapter for 12 th class😂😂

[classroom]

Nobody -
Few people on every educational video- you are the best teacher. Before this i never understood this topic 🤪😆

[kritikagaur]

Who is studying it in 12th to understand continuity ...🙋‍♀️😂
