Question

Use the dot product to determine whether the vectors are parallel, orthogonal, or neither. v =SQUARE ROOT 2j, w = 4i

A. orthogonal

B. parallel

C. neither

Answer 1

If they were parallel, their dot product would be their lengths multiplied. If they were orthogonal, their dot product would be zero. These are actually quite simple to find, because they only have one component each. Because their components are in orthogonal directions, they must be orthogonal as well.

Answer 2

OH OKAY I UNDERSTAND FULLY NOW
