This course is a study of ordinary differential equations with applications in the physical and social sciences. Topics include: Definitions and Terminology, Solutions, Implicit Solutions, Families of Solutions and Systems of Differential Equations. This course contains a series of video tutorials that are broken up into various levels. Each video builds upon the previous one. Level I videos lay out the theoretical frame work to successfully tackle on problems covered in the next videos. These videos can be used as a stand along course or as a supplement to your current differential equations class. This course is consistently being populated with new videos. This course is for anyone who wants to fortify their understanding of differential equations or anyone that wishes to learn differential equations can benefit from this course. This course is consistently monitored ready to reply to any questions that may arise.
