15. Constant coefficient second order linear ODEs, part 2 (Notes on Diffy Qs, 2.2)

An undergraduate course on differential equations aimed at engineers and other STEM fields. In this lecture, we continue looking at how to solve constant coefficient second order linear ODEs. We will solve such equations when the characteristic equation has complex roots. The book for this course is at https://www.jirka.org/diffyqs/ The book is free to download as PDF, or browsable as webpages, or you can buy an inexpensive paperback version (best way to support this project).
