## Main Question or Discussion Point

I took diffeq 2 last semester and the book we used wasn't so great at explaining a lot of things. I was wondering if anyone knew of a video lecture series that parallels my book (Differential Equations 4th Ed. by Blanchard, Devaney, and Hall). Specifically I am having trouble with how to use series and linear algebra to find solutions for systems with complex eigenvalues and how those solutions behave graphically. Also, there is a bit about Frobenius' Method and a power series method for finding non-constant coefficients that I am having issues with.
