Publisher's Synopsis
We often need to represent physical quantities such as mass, force, velocity, acceleration, time, etc., mathematically. Most of the physical quantities that we need can be classified into two types: scalars and vectors.Section 1 defines a vector and discusses ways of representing vectors in two dimensions. Section 3 discusses another way of representing vectors, one that easily generalizes from two to three (or more) dimensions. Sections 2 and 4 consider ways of operating on and combining vectors - that is, they provide the fundamentals of vector algebra.
