Worldwide Differential Equations with Linear Algebra by Robert McOwen??ISBN 9780984207121Publisher : Worldwide Center of Mathematics, LLC; 1st Edition (January 1, 2012)This textbook is designed for a one-semester undergraduate course in ordinary di erentialequations and linear algebra. We have had such a course at Northeastern Universitysince our conversion from the quarter to semester system required us to o er one courseinstead of two. Many other institutions have a similarly combined course, perhaps for asimilar reason; consequently, there are many other textbooks available that cover bothdi erential equations and linear algebra. Let me describe some of the features of mybook and draw some contrasts with the other texts on this subject.Because many students taking the course at Northeastern are electrical engineeringmajors who concurrently take a course in circuits, we always include the Laplace transformin the rst half of the course. For this reason, in my textbook I cover rst andsecond-order di erential equations as well as the Laplace transform in the rst threechapters, then I turn to linear algebra in Chapters 4-6, and nally draw on both in theanalysis of systems of di erential equations in Chapter 7. This ordering of material isunusual (perhaps unique) amongst other textbooks for this course, which generally alternatemore between di erential equations and linear algebra, and put Laplace transformnear the end of the book.
