2:35:32 Sir won't a.b = 0? As a = 3, b = 4, c must be 5 as they are forming a triangle. Then angle btw a & b must be 90 as c is hypotenuse. This a.b = 0. Right?
1:54:23 Sir, I used another method which goes as follows |a-b|²+|a-c|²=8 -> i let theta be the angle bw a and b and phi be the angle between a and c Then in 'i' |a|²+|b|²-2a.b+|a|²+|c|²-2a.c=8 therefore 4-2(costheta+cosphi)=8 -2(costheta+cosphi)=4 costheta+cosphi=-2 It can be inferred that this is possible only if theta=phi=pi So angle between a and b is pi i.e they are anti parallel and the same with a and c So a+2b is the same as a-2a=-a(since both are unit vectors and in opp dirn) and a+2c is also the same as a-2a=-a therefore, |a+2b|²+|a+2c|²= |-a|²+|-a|²=2 Just thought I'd share if someone else finds it helpful.

Sir won't a.b = 0? As a = 3, b = 4, c must be 5 as they are forming a triangle. Then angle btw a & b must be 90 as c is hypotenuse. This a.b = 0. Right?
Why c must be 5 ??
c can be any no. which is less than sum of a and b ( triangle inequality theorem)

how did u find mod c?

you can study but also do qs alongside from rd
2:16:02 Guys beware 2 answers exist of this question 60 and 120 degrees❤
Concept boosted bhai❤
What a way of teaching!
1:54:23
Sir, I used another method which goes as follows
|a-b|²+|a-c|²=8 -> i
let theta be the angle bw a and b and phi be the angle between a and c
Then in 'i'
|a|²+|b|²-2a.b+|a|²+|c|²-2a.c=8
therefore 4-2(costheta+cosphi)=8
-2(costheta+cosphi)=4
costheta+cosphi=-2
It can be inferred that this is possible only if theta=phi=pi
So angle between a and b is pi i.e they are anti parallel and the same with a and c
So a+2b is the same as a-2a=-a(since both are unit vectors and in opp dirn)
and a+2c is also the same as a-2a=-a
therefore,
|a+2b|²+|a+2c|²= |-a|²+|-a|²=2
Just thought I'd share if someone else finds it helpful. Thank you.
