In unit-vector notation
WebThe standard unit vectors in three dimensions, i (green), j (blue), and k (red) are length one vectors that point parallel to the x -axis, y -axis, and z -axis respectively. Moving them with the mouse doesn't change the vectors, as they always point toward the positive direction of their respective axis. More information about applet.

Note the orientation of the x, y, and z axes.
WebThe vectors →Ax and →Ay defined by Equation 2.11 are the vector components of vector →A. The numbers Ax and Ay that define the vector components in Equation 2.11 are the scalar components of vector →A. Combining Equation 2.10 with Equation 2.11, we obtain the component form of a vector: →A = Axˆi + Ayˆj. 2.12.
