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

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.
