Cheat sheet 11! Super exciting because we finally get to start talking about eigenvectors and eigenvalues and “eigenstuff”. These are terms you’ll see if you start reading about Hermitian operators, which come up a lot when you’re talking about quantum mechanics. This sheet will also talk about how to construct matrices using eigenstuff as well as what diagonal matrices are and why they’re convenient.
UPDATE 08.31.2022: Since these sheets are now complete, styled, reviewed, edited, and published, you can pick up the whole pack of 15 in my shop here!
