The Reverse Triangle Inequality

WebIn multidimensional spaces whose elements are vectors, one often defines what is known as the scalar product and then also an angle between two vectors. Say, for two vectors a and b, if the scalar product is denoted a·b, then the angle γ between the two is defined via the cosine function as in: Web4 Vector Geometry 4.1 Vectors and Lines. In this chapter we study the geometry of 3-dimensional space. We view a point in 3-space as an arrow from the origin to that point. Doing so provides a “picture” of the point that is truly worth a thousand words. Vectors in . Introduce a coordinate system in 3-dimensional space in the usual way.
