I'm not sure if I should have opened an issue on the main course page, but since these are specific to A1, I'll leave them here:
Chapter 8 from Elementary Differential Equations by Boyce. (Chapter 7 is nice to review as well)
Chapter 6 from Classical Mechanics by Taylor (Calculus of variations)
Both books are used at UofT. I have not taken any physics courses nor numerical methods courses, so I found these resources particularly helpful in understanding the first lecture recording and for A1.
