What are the properties of vector inner product

The vector outer product is defined as: a × B = | a | ·| B | · sin. The geometric proof method of distribution law is very complicated, and the main idea is to use the method of drawing to verify. If you are interested, please refer to the proof in the reference. The algebraic method is given below. We assume that we already know: 1) the antisymmetry of outer product: a × B = -

1. The inner product of a vector is the scalar product of a vector. Definition: the angle between two non-zero vectors is denoted as 〈 a, B 〉, and 〈 a, B 〉 ∈ [0, π]. Definition: the scalar product (inner product, dot product) of two vectors is a quantity, denoted as a · B. If a and B are not collinear, then a · B = | a | ·| B | · cos 〈 a, B 〉; if a and B are collinear, then a · B =
