Sir you are very talented you explain deeply and i am very attentive in this video 48:30 thank you so much sir.

[Edu-Fusion]

You really explain very cleary sir but I want to explain those of friends who is watching this video.... so when you see video first listen what sir is explaining then stop the video after half explanation where u think to stop and then go through the book....read from beginning of the chapter and then u realize and remember whatever sir teaches makes easy to understand the chapter and than again do the definitely you will understand all the thnku ☺

[aaa]

Thank you thank you thank you so much 🥳🥳🎉🎉 looking for this type of video only explain very clearly 👍👍

[hopeworldbts]

*I hope you will read this sir although it is pretty lengthy 😅*
19:04 here in Q3. what I did was for finding the side DC I first assumed the whole triangle abc where one side is 12 and other 5. So using Pythagoras triplets I took the base AC as 13 (5, 12, 13..) and then saw that AD which was the half of AC was already given as 3 so for finding the other half I thought of subtracting 13-3 which is 10. And put the value of DC as 10 and proceeded to solve subpart 5, 6. After seeing my answers coming wrong I referred to your video and literally now am totally confused 😐.

On monday my maths exam is there for 80 marks thank u sir for teaching me these maths chapters i I following your videos from past 2 months
THANK U SO MUCH SIR

[harveersinghyadav]

How Many Students Have Exam On Monday😂😂😂😂😂

[artandcraftwithjiya]

7:07 Pakistan bhukha pyasa Hindustan hara bhara 🤣🤣🤣 best way to learn, nice video sir....

If your can't use any board -marker, atleast use a dark pen so that it is visible properly 🙏🏻

[ramitha.v]

[sahibjotsinghdhaliwal]

I like your explanation sir coz u explains very clearly and deeply a concern of every topic given keep it up #gbu👍🏻👍🏻

[killermutant]

Thank you sir for explaining trigonometry so easily 😊. We really appreciate it.

[debarjunsaha]

Today i m having exam and I don't know anything about trigonometry thanks sir for helping mee

[ichigouzamaki]

18:20 or something u should have done cosec directly from the start cuz 1/sin is cosec and when u did 1/sin it become h/p and h/p is for cosec

[mohammedomarkhanmiya]

This is the video I was searching explaind very well sir ❤ thanks

[ShilpaShilpa-ojuh]

One suggestion....Use Little dark coloured pen. Sir..

[jinovijigeorge]

in ex (22A) iii or vi
If it was asked in an exam ....should I write the steps or can I write the answer directly ?

[shikhaverma]

Dude use dark and thik pen for solving the question so that we can see solution clearly
