WebA unit vector in the positive direction of a coordinate axis is called a standard unit vector. There are two standard unit vectors in R2. The vector i =[1 0] is parallel the x -axis, and the vector j = [0 1] is parallel the y -axis. Vector names i and j are reserved for standard unit vectors in the direction of x and y axes, respectively.
