Elementary Differential Equations, by Boyce and DiPrima,
1. Background and Goals. Differential equations are
used to describe processes that vary continuously
with respect to
time. In applications, one often knows some relationship between an
(or system of functions) and its derivatives, and
uses this relation to determine the original function.
covers the basic theory of ordinary differential equations. This
includes stability theory
and the existence and uniqueness of
solutions, and techniques of solutions for linear systems of
2. Exams. There will be a midterm in-class exam on
