1. Definition of the product of quantity of a vector: If two non-zero vectors a, b are given as OA=a, OB=b, then the angle AOB is called the angle between vector a and vector b, and is denoted as 〈a, b〉 and 0≤〈a, b〉 is defined as: the product of quantity (inner product, dot product) of two vectors is a quantity, and is denoted as a•b. If a, b are not collinear, then a...
