Okay, if anyone is like me who is interested in Linear Algebra and not necessarily Differential Equations, but still wants to understand this lecture for the sake of completeness in this course, here is the list of all the Differential Equations theory you need for this lecture and where you can find content to learn it:1. Separable differential equations - Khan Academy - this is for v(t)=exp(Lambda t) v(0)2. 2nd order linear homogeneous equations - Khan Academy - you need this if you want to understand one calculation in the next item on this list (quick to learn anyways)3. Systems of differential equations - MIT OCW 18.03, lectures 24 and 25 - basically does the first example in this lecture, but actually goes through the steps of explaining what is happening, highly recommended to watch both videosAs someone who is unlikely to apply a whole lot of differential equations in the future, I still found this lecture useful to reinforce the properties of Eigenstuff from the previous lecture, also the very last bit of the lecture is very cool####[]
