(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Which of the below vectors are A). Orthogonal B.) in the same direction C). in opposite directions

2. Relevant equations

Vectors:

u_{1}= (1,2)u_{2}= (0,1)u_{3}= (-2,-4)u_{4}= (-2,1)u_{5}= (2,4)u_{6}= (-6,3)

3. The attempt at a solution

The text told me how to find if two vectors are orthogonal, (u*v= 0), but I don't know the procedure to use when 6 vectors are involved.

They never mentioned directions at all. :( I'm assuming it just refers to the graph running in either the same or opposite directions?

Thanks for your help!

Newb... (really!)
