Question

I really need help! Determine whether the vectors u and v are parallel, orthogonal, or neither. u = <7, 2>, v = <21, 6>

tkhunny · Answer

What is v / 3?

anonymous · Answer

What?

anonymous · Answer

Oh, and I know it's not neither. Someone told me that, and I got it wrong the first time.

tkhunny · Answer

You didn't answer the question.  You are given u and v.  What is v/3?

Show me.  It is a vector divided by a constant (scalar).  What is the result?

anonymous · Answer

Uhmm.. 
Ohhh.. Well, geez. Why could no one else make it that simple? 7, 2. So they are parallel?

tkhunny · Answer

That's it!!! I presume you managed v/3 = <21,6>/3 = <7,2> = u?

Yes! Thank you! You're fantastic. :DDD God bless you!
