CHAPTER 3 — Vector Addition

The previous chapter discussed addition of column matrices. This is an easy, mechanical procedure. This chapter shows why it is a useful procedure by discussing how it represents the geometrical operation of vector addition.

• Addition of geometrical vectors.
• Addition of vectors using the head-to-tail rule.
• Coordinate frames.
• Representing geometrical points with column matrices.
• Representing geometrical vectors with column matrices.
• Addition of vectors using column matrices.
• Vector plus point addition.
