Question

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

Answer 1

If u and v are parallel then the cross product of u and v will b =0

Answer 2

I think their orthogonal

Answer 3

u cross v=?

Answer 4

Orthogonal=perpendicular???

Answer 5

Ya they r orthogonal

Answer 6

6(2) + -2(6)
12 + -12= 0

Answer 7

Bt hw do u know they r orthogonal?

Answer 8

Ivthink u calculated dot product

Answer 9

U got
u dot v=0

Answer 10

Right?

Answer 11

I don't understand

Answer 12

Ya

Answer 13

Really? Are u sure?

Answer 14

Openstudy website disturbing little!!

Answer 15

My answers r not in orders!!

Answer 16

I thought orthogonal meant when the final result =0

Answer 18

Anyway enjoying helping u!!!

Answer 19

Actually angle between ur given 2 vectors will b 90 degree. Its called orthogonal

Answer 20

C plz

Answer 21

u dot v=0
u*v*cos theta=0
Cos theta=0/uv=0
Theta=90degree

Answer 22

Glad to help u!!!
