Question

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

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

Answer 1

if u.v = 0 then it is orthogonal, can you determine the value of u.v ? would it be equal 0 ?

Answer 2

It depends, after I obtain 48 and -48, do I subtract or add? If I add yes it is orthogonal.

Answer 3

if u = <x1,x2> and v = <x2,y2> then u.v = x1x2 + y1y2
so, use addition operation

Answer 4

you are right, it is orthogonal

Answer 5

Thank You !! :)
