9.3. Representing Vectors in Terms of Their Components in a Coordinate System Using the Unit Vectors i, j, and k

• Vectors can be represented in terms of their components in a coordinate system. The vector components can be defined by their directions along the X, Y, and Z axes of a coordinate system using unit vectors denoted by i, j, and k. The i, j, and k unit vectors have magnitudes of one and directions pointing parallel to the X, Y, and Z axes, respectively, in a rectangular coordinate system.
