Homework Statement
Calculate |u+v+w|, knowing that u, v, and w are vectors in space such that
|u|=√2, |v|=√3, u is perpendicular to v, w=u×v.
Homework Equations
|w|=|u×v|=|u|*|v|*sinΘ
The Attempt at a Solution
[/B]
Θ=90°
|w|=(√2)*(√3)*sin(90°)=√(6)
Then I tried to use
u={√2,0,0}
v={0,√3,0}
w={0,0,√6}
and I got that |u+v+w|=√(2+3+6)=√11
but I'm trying to find a way to do this problem where I don't assume that those are the vectors.
