I know this is always hard for students to understand. That's why I generally explain this in every relevant tutorial. Glad this tutorial is helpful. Pls share if you don't mind. 🙏
Thanks for your good wishes. I have spent almost a week to think and prepare to explain this derivation. The derivation given in the book or on internet is quite complex and I did not like that. So I thought of explaining this concept in the simplest possible way. I hope more students would feel it helpful. Cheers!!!
I hope you are asking about the congruence. If so, we only take the measure of the sides and angles and not the signs for congruency. Imagine 2 different sticks, each of length 3 meters, lying on a plane. We can pick any of these two and place it over the other stick completely overlapping it. Hope it's clear now.
Thnkss sir for one of the best explanation but i have 1 doubts.. During 11:10 why did u take -2 cos x cos y..?and 2 sin x sin y?...what formula to follow there?
Hello sir how are you doing Sir if you remember me i have seen your videos from starting of the channel Glad to see your channel growing sir I just wanna give you an advice sir that you can start class 11,12th applied math classes and this can help you a lot in growing
I do remember you Hardik :) Thanks for supporting me for so long. I really appreciate it. Also, I feel really happy that you have shown concerns about my channel and want it to grow more and to really great heights. I have started focusing on class 11 as of now and would like to stay focused on it for a while. I may create different videos in between but primarily class 11 be the focus. Anyway, what about you? What are you doing now? What subjects are you studying?
You are most welcome. I feel that I have put a lot of efforts in this tutorial. It will be really great if I share this video with your friends. Cheers!!!
A point ke coordinates to barabar samajh aa gye ... Pr , B ke kaise aaye.... x+y>90° hoga to vo to right triangle bnega hi nhi to usme trigo lgegi hi ni to B point ke coordinates {cos(x+y),sin(x+y)} kaise aaega
thank you so much sir✨ you helped me to get 6 marks without any doubt thanks a lot sir 🙏✨❤️🥺
My pleasure 👍 please share it 🙏

Apart, Nice Teaching I Understood 👍🏻
Punjabi hoon na ... Is liye naturally aise bolta hoon .. barabar 😎
All the best for your tomorrow's exam 😂😂😂😂

Nahi Bhai ajj hain
Tnx bhaii😅😂
Tnx bro
Tqs bro but my exam is today 😅
Thank you sir the only video where we get to understand clearly why cosx and sinx as co-ordinates

Thanks for this wonderful explanation sir ❤. In my book its not explained this easy.
Thank you so much sir for this explanation ❤❤❤😊
Suberb and concise explaination. Thank you so much sir ❤
Sir please make video for other chapters and for class 12 math🙏
Thank youu sirr i came just 1 day before my exam and u just clear my douts so easily hats off to you sirr
My pleasure. Best of luck for your exam. 👍
Thank you sirr..
Same here
Thank you so much sir for clear explanation.. ur teaching is very understandable.. helped me alot.
I am glad it helped. If you don't mind, pls share it with your classmates. I will really appreciate it. 👍

Xcordinate of B cos(x+y) or -cos(x+y) B is in 2nd quadrent
Very simple and excellent explanation.
Many Thanks sir.
Aap bahut achchhe se samajha diye hai. Thank you
Glad you liked it. It took me a lot of time to create this video. It would be great if you share it with your friends. 👍
Thank you sir,u made it complex to simple
My pleasure dear. Please share if you don't mind 👍
Thanks 😊
Tq sir very intresting and esy method teach you sir and we all request sir more videos you send sir
Thxs sir 6 marks bade aram se aagi
Very helpful video
8:10 Sir, sign se fark nhi padega kya? Magnitude/Quantity same hai sign(direction) alag hai... So x+(-y)?

thanks , very useful programme
Sir do you take math class for Karnataka state board 11 and 12 ncert.
Thnkss sir for one of the best explanation but i have 1 doubts..
During 11:10 why did u take -2 cos x cos y..?and 2 sin x sin y?...what formula to follow there?
it is the formula .. (a - b)2 = a2 + b2- 2ab

Thankyou sir
nicely explained video!
Pls share it 🙂

Thank's sir
Pls share it.
I have a dout
How -cos(-y) becomes -cosy, it should be +cos y ?????
Watch this video: th-cam.com/video/Xkyvz4knDew/w-d-xo.html
You will get it.
cos(-y) = cos y (it is given in NCERT)
then multiply both sides by -1
We've -cos(-y) = -cosy
A point ke coordinates to barabar samajh aa gye ... Pr , B ke kaise aaye.... x+y>90° hoga to vo to right triangle bnega hi nhi to usme trigo lgegi hi ni to B point ke coordinates {cos(x+y),sin(x+y)} kaise aaega
Watch this part. You will get it.

Sir do you take math class for Karnataka state board 11 and 12 ncert. Our son is in 11 th puc
I teach only on TH-cam 🙂
@@Mathemafia thank you sir
Hoping sir next time you had 1mil subscribe
Thank you sir for helping me in 10th class
Thank you and welcome. :)
Tq ssooooooo much
Most welcome. Please share it 🙃
Sir is the distance formula correct ?
what is your doubt?
Sir jii love u thanks😂
But sir the distance formula is √(x2-x1)²+(y2-y1)²
Is there any issue in the video?
🤬🤬🤬@@Mathemafia
Sir distance formula toh (x2-x1)²+ (y2-y1)² hota hai aapne (x1-x2)²+(y1-y2)² karwaya hai
(2-5)² aur (5-2)² kitna hota hai ... 🙂
Sir one is positive 3 and another is -3
❤️❤️❤️❤️❤️
👍👍🙏🙏
Sir ye proof kahan Se mila?
Mere dimaag se :)
Actually ur distance formula is wrong sir
Because distance formula is √(x2-x1)2+(y2-y1)2
How much is square of (3-2) and square of (2-3)? 😎
Cosx+y and sinx+y coordinate kis logic se bana
Can you explain your query? Also mention the time as well?
@@Mathemafia4:11 me coordinates cos(x+y),sin(x+y) kaise hua kyuki waha par koi right angle nhi ban Raha hai
Aap kiska ka reference leke coordinates nhi bata skte hai
Watch this tutorial from 3 : 30 onwards. You will get the answer you are looking for.

@@Mrdoubt-xu1ee If you still have any doubt, let me know. I will try to explain.
Distance formula is wrong
Kaise?
Yes distance formula=√(x2-x1)2+(y2-y1)2
(x2-x1)² is same thing as (x1-x2)² as (x2-x1)² = (-1(-x2+x1))²
Exponent law (ab)^m=a^m × b^m
= (-1)²(x1-x2)²
= (1)(x1-x2)²
= (x1-x2)²
Similarly for y
Thank u sir
