Question

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

u = <7, 2>, v = <21, 6>

Neither
Orthogonal
Parallel
None of these

Answer 1

multiply the first vector by "3"
what do you get ?

Answer 2

How would i do that ? 3*<7,21> ?

Answer 3

Yes, simply multiply each component by "3" :

3*<7, 2>

<3*7, 3*2>

<21, 6>


which is same as the second vector, so the vectors in "same direction"

Answer 4

vectors in same direction are also called "parallel"

Answer 5

Omg thank you .. i didnt understand what parallel ment in terms of this :x it was kind of a slow moment . thank you again
