A X B =|A||B|sinθ
where
θ=angle between A and B vector
and
|A|=magnitude of A
|B|=magnitude of B
Arpit1012:
the correct answer is (a × b)^2 = a^2b^2-(a.b)^2
but I don't know the correct method to solve it...
but u asked a X b
not a X B square
original question is same....
I write it correctly....
ohk
so what about your answer
you have another method to solve this???
