Question

Determine whether the vectors u and v are parallel, orthogonal, or neither.
u = <6, -2>, v = <8, 24>
Neither, Parallel, or Orthogonal

Answer 1

Hint: use the dot-product.

Answer 2

If two vectors have their dot product = 0, then they are orthogonal.

Answer 3

How do you know if they are equal to zero?

Answer 4

The dot product of (a,b) and (c,d) is ac+bd

Answer 5

okay let me try it

Answer 6

So it equals 0 which means its orthogonal?

Answer 7

Yes

Answer 8

Aw thanks(:

Answer 9

No problem
