Your explanations are the best!
I was struggling with this question a lot because of that minus sign. Finally I got my answer . Thank you sir . My words cannot adequately express my gratitude for you 💖💖💖💖
You're most welcome. I am glad that my videos are helpful.
I conducted a live session today regarding the live sessions :) that I am going to conduct on regular basis. I hope you will like to join in future. Checkout its replay here in case you have not watched it yet ua-cam.com/video/OMQ47TmOt74/v-deo.html. Send me your feedback about the new setup. I will really appreciate it.
Me to was struck in same
Same oh my god

Your presentatiom and way of teaching is really great
Thank you so much for liking my way of teaching. I need a lot of support from students to make my channel grow. Pls share it if you don't mind. 🙂
I don’t think so 😅 cause there are better ways
Watch complete chapter here: ua-cam.com/video/o1n-m0kWBGU/v-deo.html
ALL doubts Crystal Clear Sir...UR VDOS R SOO HELPFUL...🤗
If you replace 1 in numerator then you will get tan+sec and if you replace 1from denomerator then you will get 1/tan+sec
Sir why you don't teach us regular chaper wise .. i really like your explanation... the way you tech is very awesome ❤
Very nice explanation better than my tuition teacher
5:46 minus bhar nikhalna wala concept samaj ma nahi aya sir
We need (sec θ - tan θ) in both the terms for factorizations. That is why I have taken out minus. Just watch it again - I have explained in detail. Fir bhi kuch confusion ho, let me know, I will help.
Well explained with clarity… amazing work
Thanku so much sir☺️☺️
But sir (sec-tan) aur -(sec-tan) cut bhi to ho sakta he
I think there is an addition sign in between.
Also, if we cut them, we won't get the desired answer... 😊😊
I kept forgetting this ques I don't know why?
Same
2:50 "rearranging the numerator and denominator" could you provide me some more examples of this step? Is this allowed with numbers as well? Are there any conditions to it?
No ❤
@@Sammy-wh3vo Ok but this looks so backhanded 😭
@@ericj199 cz it is lmao
@@Sammy-wh3vo chill, it was a year ago; admittedly, I was dumb. No need to be mean
well explained sir
thank you
Thank youuu soo much for the wonderful explanation
Best explanation sir
I can't solve this question...my mind stuck on minus sign....
But but but
Becoz of your video i understand it in first time😃😇👌👌👌👍
Glad to know it helped. Keep watching and supporting.
6:40 I didn't understand this method but got the answer by following ur steps..still tq

Welcome
Thanks you so much sir g.
The last keep watching matsssss mafiaaaa was epic🎉
Really very good explanation sir😅so much helpful
Thank you. Please share it
6:07 i didn't understand why and how u took - minus as common
Thank you sir for your explanation
Welcome
Amazing explanation
ily sir
Thank you so much sir
Well explained thanks
Welcome. Please share it 🙏
Tq sir
Thx so much
Sir make a video on last part that you have given suggestion.
Try yourself. That will help.
9:29
❤❤❤ thanks sir really helpful ❤❤❤
Better option is to change numerator into sec^2A - tan^2A
Then you dont have to take minus common
How??
Easiest explanation I've come so far... Thanks
Great to hear!
Wow great ❤
Could you make a revision video on this chapter for standard maths?
Also your channel's an absolute gem! Discovered it after quite some while but glad I did
Very easy now
Sir first comment 👍🏻👍🏻👍🏻
👍🏻
Bro..... Thank you so much !!!
You're welcome! Pls share it.
9:27 😂
Sir aapne kaha upr niche dono trf 1 ko identity me convert kr skte h 😑 but mene jub upr liya to vo upr hu bacha h niche chaiy to niche hi lena hoga
Pls explain your query.
Jai Jai physics Wallah 🙏🏻✍🏻
Bilkul. Par main to Maths wala hoon 😎
wow@@Mathemafia 😂😂
I have watched this 5 times still didn't understand 😭
Watch it once more at slow speed and pause in between to grasp the concept. You will get it.
Thank uuuuu bhaiyaaaaa so much yaarrrr
Welcome. Pls share it.
Sir can you give a hint for a second approach, as to how to solve the rhs side ?
It is always recommended to move from more terms to lesser. On left side there are 3 terms in numerator and denominator whereas on RHS, we have only 2. So converting 2 terms into 3 will need some kind of manipulations, most of the times.
@@Mathemafia thanks sir would always keep this in mind, all the chapter are quite an easy sail for me but this trigonometric identities are quite a hustle sir. More questions i try outside ncert more comfused i am, any hints or tips sir?
And sir would you mind solving the alternate method further which you hinted in the last minute of video.
@@VishalYadav-yg9ug I explained how to remember trigonometric identities yesterday in my live session. Either you watch that video or you can ask it tomorrow in live session. I will explain if time permits.
I have clearly explained what to do next to solve it with the alternate method :) Just do that. It is almost already solved.
@@Mathemafia sir i remember all the identities, problem is comprehending the question and to understand which math functions to apply so as to get the desired result.
❤ ☺️
8:06 me common vala samajh nhi aaya
Slow pace par pause kar kar ke dekho... aa jaayega samajh.
Common Lene se pahle Tak sab samajh mein aaya but uske bad upar se gaya hai😢😢😢😢😢😢😢
sir i think this is example 15 ig
Nhi sir yaha "koi harsh nhi hain"
Kitna paper lenge sir😂
Sir muhje nahi samaj Aya 2 baar dekha phir bhi😢
Common se pahle Tak samajh as rha tha 😢😢😢😢
Slow speed pe fir se dekho... pause kar kar ke.. aa jaayega samajh.
Common galat nikala hai bhai
kya galat hai?
Thank you sir you are the best 😊
