In this video I go over unit vectors, which are vectors of length 1. Any vector "a" can be expressed as a unit vector "u" pointing in the direction of "a" by dividing the vector "a" by the length |a|. This produces an unit vector with length 1, which I also go over a simple proof that this is indeed the case. I also go over an example in calculating the unit vector of a given vector.
