This course is MAT 2680, Differential Equations, taking place in the Spring 2019 semester with Professor Reitz. Â We will be using this website in a variety of ways this semester â€“ as a central location for information about the course (assignments, review sheets, policies, and so on), a place to ask and answer questions, to post examples of our work, and to talk about Â mathematics, physics, reality and so on.
