Let U= |-1| |2 | |1 | V= |3 | |1 | |-1| Find: || [1/(||U-V||)](u-v)|| Starters? Thanks in advance

You can compute that expression without doing any numerical computations, if you use some of the properties of norms, such as || av || = |a| ||v||. Does this give you some ideas?
What can you say about the length of ?
I don't get it...please explain more Thanks
You would agree that is a scalar, right? And it's positive? So
If is a nonzero vector then That is all there is to it.
So does it end up being = 1? because you times the thing up.?
Well, I don't know what you mean by "times the thing up". You have a/a, where a is not zero. That's always 1.
Why don't you know the basic properties of the norm function? If is a scalar and is a vector then . Therefore
Because I am a high school student trying to learn University alg by using a text book that doesn't teach anything.
Technically, it's Be careful with your parentheses!
