Dot products and duality | Chapter 9, Essence of linear algebra

Why the formula for dot products matches their geometric intuition. Help fund future projects: An equally valuable form of support is to simply share some of the videos. Home page: Dot products are a nice geometric tool for understanding projection. But now that we know about linear transformations, we can get a deeper feel for what's going on with the dot product, and the connection between its numerical computation and its geometric interpretation.
