Vectors | Chapter 1, Essence of linear algebra

This segment introduces the concept of a vector in linear algebra by contrasting three perspectives: the physics student's view (arrows in space), the computer science student's view (ordered lists of numbers), and the mathematician's abstract view. It establishes the standard geometric representation of vectors anchored at the origin of a coordinate system. The video then defines the two fundamental operations on vectors: addition, demonstrated via the tip-to-tail method and component-wise arithmetic, and scalar multiplication, explained as scaling (stretching, shrinking, or reversing) a vector.
