In this video, I define the concept of orthogonal projection of a vector on a line (and on more general subspaces), derive a very nice formula for it, and show why orthogonal projections are so useful. You might even see the hugging formula again. Enjoy!
This is the second part of the orthogonality-series, but can be watched independently as well. Here is the link to the first part: • Orthogonal sets
