6.5. Vector ProjectionsΒΆ

The outline of this page comes from lecture 15 of Dr. Strang’s Linear Algebra course at MIT. [STRANG99]


This topic is provides a very important application of linear algebra to engineering problems.

Normally, I like to introduce a new topic by beginning with an explanation of why it is important. In this case, the explanation of why it is important will make more sense after reviewing the simplest case. So bear with me for just a little pure math and then we will get to the application and discuss extension of the concept to more dimensions.
