... vectors and the skew geometry that comes from eigenvectors. One leads to singular values and the other leads to eigenvalues. Examples are amazingly powerful. I hope this family of 2 by 2 matrices fills a space between working with a specific numerical example and an arbitrary matrix. 2. The Four Sub ...

... C x = b is not always solvable. The words that express the contrast between A and C are a crucial part of the language of linear algebra: The vectors a1 , a2 , a3 are independent. The nullspace of A (solutions of Ax = 0) contains only x = 0. The equation Ax = b is solved by x = Sb. The square matrix ...
