I've decided to release some selected (previously unlisted) lecture videos from my calculus classes to the public. I don't plan on doing this for many videos. The main reason I'm doing this is to see how well these lecture videos appear on my cell phone, and to see how many views I get and where the videos show up in search results.
In this video, I discuss the component and the projection of one vector onto another nonzero vector. The definitions are derived from geometric considerations. Several examples are given, including the calculation of an orthogonal decomposition and the work done by a force applied at an angle.
