vector, and (x2,y2) is (1,1), because that is the ending point. Unit Vectors: The term unit vector is used to define a vector that has unit length; i.e length=1. Figure 6: Defining a new vector of length 2.12 If we have a vector, for example (1.5, 1.5), and we calcluate its length using the formula
