+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.How did we split the original determinant as this what sir has written and why is the 3rd column=0 im not getting it
Bro Maths is a thing of doing
Have u tried to solve it by own ?
If yes then I don't think so ki isme kuch doubt waala hai
Just expand through trigono and split it
Rest u will get the direction
One more advice :- Before solve jee questions of det and mat
Solve ncert first
Especially examples in det
Expand kardiya bhai par ye sawaal sir multiplication of determinants ke sath solve kr rhe hai
I udnerstood all other problems sir solved using this concept but got stuck in this one
NCERT I finished as part of school
Well as the way I said
It's how the u could prove it. I'll give a though to the way sir have tried to solve it when I'll have free time.But as Mohit sir himself solved it it can't be wrong
Uk what I get it
If u have a closure look sir have told through it that the Q is a multiplication of these 2 det and individually if u solve each of the det it's det gonna come out 0 and though the det in q is nothing but the multiplication of these 2 it's det well also be 0
Let me know if I'm right
How did you take cosPcosQ, cosPsinQ and sinPsinQ common?
Well u need to go through basics and ncert again
we good dude?
Ooh got it actually I forgot about this doubt but now I came back to it and it seemed really obvious thank you Bhai 😃
Yes!
