Took a break for the holidays and forgot to publish this sheet until just now - oops! But here it is, cheat sheet 9 of the series. In this one, I cover linear operators, invertibility, determinants, and the relationship between the determinant and geometry.
Next time, we’ll finally get to look at eigenvectors and eigenvalues (concepts I’ve heard referenced a lot over the past year that I haven’t been able to dig into until now).
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!
