Question

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

u = <3, 0>, v = <0, -6>

Answer 1

From the previous question, you know how to find dot product of 2 vectors, right?

Answer 2

Yes, I believe so.

Answer 3

then, do it again, if u dot v =0 , then u and v are orthogonal

Answer 4

0,0 Does this mean it is orthogonal?

Answer 5

hey, dot product is a NUMBER, not a vector, hence the result is 0, not (0,0)
and you are right. they are orthogonal

Answer 6

Review the previous post. You get -41, it is a NUMBER,right??

Answer 7

Yes? No? your sister want to go to bed but I don't want to leave before making it clear.

Answer 8

So it is orthogonal then.

Answer 9

ok

Answer 10

what was that about his sister?
