This is the playlist for Math 334 of Summer 2017 at Liberty University. I'm using Nagle, Saff and Snider's "Fundamentals of Differential Equations and Boundary Value Problems" 4th edition and my notes. The course website is: http://www.supermath.info/DEqns.html where I have many resources posted. Naturally, I'll use Blackboard, wait, I should say unnaturally but out of habit to be more honest, to post the actual syllabus etc. I hope to have the Lectures posted the same day if all goes as planned.
