Our recent textbook Linear Algebra for Everyone starts with the idea of independent columns This leads to a factorization A = CR where C contains those independent columns from A

I am happy for you to see this Fifth Edition of Introduction to Linear Algebra. This is the text for my video lectures on MIT’s OpenCourseWare (ocw.mit.edu and also YouTube).

Linear combinations can fill all of space, or only a plane. We need a picture to show the crucial difference between u, v, w (the first example) and u, v, w∗ (all in the same plane).
