What's this about?
Often, you want to have a vector of length one, e.g. cause it simplifies length calculations.
How to get a vector of length 1?
Simply take any vector, calculate its length and divide the vector by its length. This
new gotten vector has length 1. This technique is called norming. It is especially interesting because you only change the length
and not the direction of the vector.
Can I see an example?
Of course. Just enter your vector and it will be normed.
