Question

can someone explain to me how to determine if two unit vectors are parallel? I'm not understanding the concept

Answer 1

if they are constant multiple of one another then they are parellel

example

{1,3}

{2,6} =2* {1,3}

same idea with unit vector

Answer 2

where did 2 and 6 come from?

Answer 3

in your example

Answer 4

oh...is this like factoring so to speak?

Answer 5

oh, I just made up two vector

{1,3} and {2,6}

Answer 6

so 2 is a scaler of both vectors?

Answer 7

They are parellel because one is constant multiple of another,2

{1,3}*2 ={2,6}

Answer 8

These two would be parallel too
{1,2,4} {4,8,16}
