Vector Notation and Operations

This video tutorial introduces the concept of vectors, starting with basic ideas and notation. It explains 3D coordinates and how to plot points in space, using examples of points A and B. The tutorial covers how to define vectors from the origin to these points and how to calculate vectors between them. Different vector notations are also discussed, providing a comprehensive understanding of vector representation.
