Let's review some basic formulae for planes in 3-d. What do we do with vectors? One source of utility comes from basic vector algebra. Let's consider how to add and rescale vectors. Let's think about what the determinant means from a geometric view, starting with the What is multivariable calculus, and why do we need to begin with the linear algebra of vectors & matrices? Here's a preview of ... The cross product is a great operation on vectors in 3-d that takes two vectors to a new vector. It's a little complicated-looking at ... What have you learned in this chapter? Think about it and make sure you've got the Big Picture. If you're looking to review, you ...
As a first example of a linear system, let's recall stochiometry, or basic equation balancing, from chemistry. There's a simple ... We may understand determinants from both algebraic and geometric perspectives, but there's one more critical perspective, and ... Do inverse matrices exist? Sometimes, but not always. Let's consider a few examples in the
