Summer 2020: Math 2255 (Ordinary Differential Equations)

Below are the recitation notes that I used while I was a grader for Math 2255 at the Ohio State University in the Summer of 2020. Technically, holding recitations for the students was not part of my job assignment, but I decided to do so anyways in order to practice my online teaching. For the notes that are typed, I have also separately included the source files. My latex source files use this class file.
