Question

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

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

Answer 1

orthogonal means U dot V =0
parallel means U = Vt, for some t
If vectors are not either parallel or orthogonal, they do not satisfy either of these criterions (and means they intersect in R^2)

Answer 2

here you see that u dot v = 12-12=0

Answer 3

so they are orthogonal

Answer 4

Yes i remember that, I'm just unsure how to solve it

Answer 5

Oh! duh! Thank you i get it
