CHAPTER 5 — Vector Direction
This chapter discusses a second important vector property:
The previous chapter discussed the length of a vector.
These are the two properties that define a vector.
- Orientation of 2D vectors (represented in a particular coordinate frame).
- Ambiguity when using arc tan to calculate angle.
- Converting length and orientation into components of a column matrix.
- Radians and degrees.
- C and Java programing with arc tangent.
What do you suppose is the direction of the vector represented by:
