Question

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

u = <6, -2>, v = <8, 24>

Answer 1

find the dot product first
<a,b> dot <c,d>
=ac+bd

Answer 2

if u dot v =0 then u and v are orthogonal .

If u dot v doesn't equal 0, find magnitudes of both and see if you have either
u dot v=|u||v| or u dot v=-|u||v|. If you have one of those two thingys I just mentioned then u and v are parallel.

Answer 3

Thank you i was confused about the whole dot but now i understand
