Question

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

*MEDAL WILL BE AWARDED*

Answer 1

what is the dot product of the two vectors?

Answer 2

<12,-12>?

Answer 3

the dot product will have you multiply the corresponding coordinates like you did just now

but you'll also add the two products to get a single number

Answer 4

so 0 which means its orthogonal? right?

Answer 5

very good

Answer 6

whenever the dot product of two vectors is 0, the two vectors are orthogonal (ie perpendicular)

Answer 7

THAN YOU!

Answer 8

thank*

Answer 9

you're welcome
