Sir can you please tell me , how can I get your dpp sheet or module or whatever you have for practice regarding this video I am a 10 th grader your videos are so amazing 🤗🤗, I am able to understand each and every concept , but please tell me how can I access you dpp
It's about perspective think with the pov of car or diagram.Imagine yourself standing near sir and facing camera then your south will be done and left will be east.
Sir , I cannot afford praveen batch. If I purchased it, exectations of my parents for my selection will increase, as they can't afford and there will be huge pressure on me. Its a humble request to provide test series only at affordable price with installments.
Dekho yaar, jab bhi baat change ki hoti hai tab subtraction hota hai.. Toh usi karan Vi - Vf hoga.. arthat yeh hoga Vi + (-Vf) Ek aur baat boldeta hu ki jab Vi + Vf ki baat hoti hai toh Vi aur Vf ke beech ka angle hota hai θ aur jab Vi aur (-Vf) ke beech ka angle hota hai (180 - θ) Aur Cos(180 - θ) ka value -Cosθ hota hai Isi karan, last question me *-2cosθ* hoga
Sir your are the best physics teacher I have ever seen.
Truee
jee nikla bhai?
Bro what are you doing now? Which College?? Please reply...I need your guidance... please bro..❤
Thanks alot to whole team of competishun for giving quality content🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
Sir online me offline ki feeling aa rahi h
Superb sir
Bro jee nikla❤️
Sir please cover also electrostatics and magnetism portion it's a huge request.... By the way sir aapka explanation bahut sahi hai...
Thank you sir for Free Quality lectures 😇
this is excellent....thank you sir....and sir also i think you is the best physics teacher in world......
sir meri gf vector h ya scalar kyunki usne mujhe directionless krdiya ☠☠☠☠☠☠☠
Bhai kya kar raha ha ye sab padhle😂
GF ka pata nhi but You are scalar now
Ek thappad padega sab samjh me aajayega chuzzs
Null vector 💀💀
😂😂
"Mera Sir" I follow you ❤️🥰
Thanx sir.. 😄
Sir khub bhlo 😇😇😇😇😊porai
Best teacher 🙂
Best teacher jee mains teacher
Thank you SIR!!!
Sir, are these lectures enough to solve materials 😢
Explanation is wonderful sir
Yes, these lectures are more than enough to solve the material. Just make sure to practice consistently!

Gods you all are. Thank you sir. Because of you teachers people like me who can't afford could study
Sir 21:00 ke aas pass tan thera hi kyu liya,,,
Kia baar ap sin theta cos theta lete ho,,,. Ye kaise pta lga ye,, koi madad krdu
hai please batao agar tumhe pata laga toh
@@pratikstudieslearnsandgrow-n5g kuchh bhi lo thetha find karne se matlab hai
Why we are using root a2 +b2instead of using a2+b2-2ab cos theta please reply
Bcoz cos 90 is zero
according to parallelogram law of vector addition their are 3 special case this is one of them. it's given in lecture no 31 at 20:08
BECAUSE cos 90 is 0
bhai shayad tumhai ab tak pata hogaya hoga par tabhi bataraha theta is 90 degree special case hai tabhi orthogonal hai toh 2ab cos 90 = 0 tabhi a2+b2 karte
Same Doubt!
Thank you sr

You can solve mathematical tool sheet of resonance if you see all these videos you can solve that sheet of resonance

Sir yee last question main ye jo add ki sir - 2abcos kyun likhe + kiyun nahni hue
Kyuki yahan ham vectors minus kar rahe hai. Dusre questions me sir ne a+(-b) karke diya tha but yaha direct a-b kardiya. Bujhe?
Thank you very much sir
Sir last question me direction ka kya hua???
Sir when will you start unit and dimensions?????
Thank you ❤️ so much sir
Sir plzz.... Tell me are offering new maths video
Sir left me west ki taraf mudega na?
nhi mene bhi yhi socha par north de south jayege aur left lene to east jayega
Sir aapne 3.10 sec par dono ki tail join Kar di hai fir add Kiya h par ye to wrong hoga sir

Why did sir has choosen π-theta 2:37
Brother remember π as 180°
Now line of -b vector and b vector forms a straight line, then it will be π-theta

Can someone answer left east ki trf kyun hoga??

Dpp kaise milega sir
I have it.. pls tell me a way where we can connect .
It's not a scam
Hello tan-¹ ka value nikalna konse lecture me sikhaya tha
@anikisplaywithmcpe2659 issi ke pichle lecture mein. Lec number 31 aur waise bhi formula hai bsin(theta)/ a+ bcostheta. Smjhe hamalkhor
Where is dpp
17:56 why is east left??????
lol
Same que🤔
Because if someone is moving in the south he is facing south try to visualise it
Because it is with respect to the car driver
Just visualize you are driving the from north to south direction and u want to take left

Watching on 4 April 2023
Sir cos (pie - theta ) = -cos theta
Kaise hua please bta dijiye
Identity: cos(A-B) = cosAcosB + sinAsinB
cosπ = -1, sinπ= 0
So -1*cos(theta) + 0*sin(theta) = -cos(theta)
I hope this helps
cos (π-θ)
=cos (180°-θ) [we know that, π=180°]
=cos (90x2-θ) [cos θ is negative in 2nd quadrant]
= -cos θ

Anyone please help last question mein
*-2cosθ* kyo use kiya hai😢😢😢😢😢😢
Dekho yaar, jab bhi baat change ki hoti hai tab subtraction hota hai..
Toh usi karan Vi - Vf hoga.. arthat yeh hoga Vi + (-Vf)
Ek aur baat boldeta hu ki jab Vi + Vf ki baat hoti hai toh Vi aur Vf ke beech ka angle hota hai θ aur jab Vi aur (-Vf) ke beech ka angle hota hai (180 - θ)
Aur Cos(180 - θ) ka value -Cosθ hota hai
Isi karan, last question me *-2cosθ* hoga
Accha ye toh samajh aa gaya lekin ye keval isi question me lagega aur ye un question me nahi lagega jinme vf-vi hoga
Aur ek aur baat ye last bale question me direction ka kya hua isse kya bhool jayenge iss question me
