Linear algebra + partial fractions review (25:45 min video),
slides (pdf),
annotated slides (pdf):
View anytime before the end of week 1
We will use several concepts that you have seen before in linear algebra. While you do not need an abstract understanding of these concepts for this course, it can be helpful (especially for future courses and out in the real world) to see how concepts that seem different can be very similar (for example, working with vectors, polynomials, or solutions to linear differential equations).

Thm 2.4.2 can sometimes be used to determine if an IVP has a unique solution, but it cannot be used to determine the domain of that solution. In this video, we first use Thm 2.4.2 to determine when $y' = 1/[(1-t)(2-y)$, y(t_0) = y_0 is guaranteed to have a uniqe solution. We then use a lot of algebra and a little bit of calculus to solve this DE and determine the domain of this solution when the initial value is the point (0, 1).
