Question

Determine whether the vectors u and v are parallel, orthogonal, or neither.

u = <10, 0>, v = <0, -9>

Answer 1

find their dot product, if their dot product is 0, they are orthogonal

if one vector is a "multiple" of the other, then they're parallel

Answer 2

ok

Answer 3

the dot product is zero,so?

Answer 4

yeap, so they're orthogonal, perpendicular, then :)

Answer 5

yep, thanks

Answer 6
