Hi guys, in my college we have this "Independent Study" component for the Intro Linear Algebra class. Basically, I have to solve 4 questions that go beyond what was covered in class. Sadly, being the procrastinator I am, I haven't looked at it until now and the assignment is due Friday. The questions look simple and non-conceptual. So far, I have a very strong understanding of: Gaussian Elimination Inverses using adjoints Finding determinants Orthogonality Cross Product Was taught a little bit of: Subspaces Linear Independence Basis I've also already taken single variable, differential and integral calculus courses. So now in the next 24 hours I have, what resources (online) would help me the most to just be able to solve these 4 questions. Normally, I like to learn something thoroughly but this time it's an exception. I have the Howard Anton "Elementary Linear Algebra 10th Ed. Abridged" Textbook but it doesn't contain these topics. Thanks.
