Vectors-Algebra and Geometry
2.1 Vectors A directed line segment in space is a line segment together with a direction. Thus the directed line segment from the point P to the point Q is different from the directed line segment from Q to P. We f

Introduction to Vector Geometry
Vectors in the Plane
The 2-dimensional plane is described by a pair of axes labelled X and Y . Each point in the
plane corresponds to the ordered pair of real numbers, consisting rstly of its X -coordinate and

I.1 Points and Vectors
Each point in two dimensions may be labeled by two coordinates (a, b) which specify the position of
the point in some units with respect to some axes as in the gure on the left bel
