Bro what are you doing now? Which College?? Please reply...I need your guidance... please bro..❤

sir meri gf vector h ya scalar kyunki usne mujhe directionless krdiya ☠☠☠☠☠☠☠

[@pranabchowdhuryxia2325]

this is excellent....thank you sir....and sir also i think you is the best physics teacher in world......

[@bhoomikarajput4119]

Why we are using root a2 +b2instead of using a2+b2-2ab cos theta please reply

[@shrutipandey7593]

Bcoz cos 90 is zero

[@itsmeHeroSeven]

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

[@geetapathak9458]

BECAUSE cos 90 is 0

[@loveveshbhaipatel303]

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

[@alokrichhariya_]

Same Doubt!

Sir, are these lectures enough to solve materials 😢 Explanation is wonderful sir

[@MohitTyagi]

Yes, these lectures are more than enough to solve the material. Just make sure to practice consistently! -Team Competishun

[@techieindian467]

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

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

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

[@ananyasingh5409]

Anyone please help last question mein *-2cosθ* kyo use kiya hai😢😢😢😢😢😢

[@derp9327]

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

[@maheshgupta2915]

Accha ye toh samajh aa gaya lekin ye keval isi question me lagega aur ye un question me nahi lagega jinme vf-vi hoga

[@maheshgupta2915]

Aur ek aur baat ye last bale question me direction ka kya hua isse kya bhool jayenge iss question me

[@ishaanjain694]

Sir cos (pie - theta ) = -cos theta Kaise hua please bta dijiye

[@Ndiedddd]

Identity: cos(A-B) = cosAcosB + sinAsinB cosπ = -1, sinπ= 0 So -1*cos(theta) + 0*sin(theta) = -cos(theta) I hope this helps

[@snigdhasaha6797]

cos (π-θ) =cos (180°-θ) [we know that, π=180°] =cos (90x2-θ) [cos θ is negative in 2nd quadrant] = -cos θ
