- 4.2: Vectors
- This page introduces the concept of vectors in linear algebra as one-dimensional arrays of real numbers, typically arranged in a column. The text explains how to represent vectors and scalars using mathematical notation and describes vector operations, such as addition, subtraction, and scalar multiplication. It points out the geometric representation of vectors in n-dimensional space and how vectors can be visualized, even in dimensions higher than three, to gain geometrical insights.
