Dual Space

Dual spaces and linear functionals
In this video, I introduce the concept of a dual space, which is the analog of a "shadow world" version, but for vector spaces. I also give some examples of linear and non-linear functionals. This seems like an innocent topic, but it has a huge number of applications, which you'll see in subsequent videos (or check out the playlist below)
