I’ve posted the solutions to yesterday’s perfectly optional quiz. The class’s performance on this quiz overall wasn’t as high as I’d like to see, so I plan to include some Lin Alg questions on the upcoming “real” Canvas quiz as well, as a motivator. Be sure to re-read those chapters, or re-watch those videos, and to ask questions about anything you’re fuzzy on! And be sure you understand the answers to this quiz, of course.
