I. Course Description

An introduction to ordinary differential equations and their applications. Topics
include first- order equations , second- and higher- order linear equations,
vibrational motion, electrical circuits, power series solutions, Laplace transforms,
systems of equations , numerical methods, and matrix methods for systems of

II. Prerequisites

Math 173-174 (Calculus with Analytic Geometry I-II) or equivalent.

III. Introduction

This course is an introduction to ordinary differential equations and their
applications. In this course, it is expected that the student will not only become
proficient in solving many classes of differential equations by hand calculations, but
will become familiar with how to solve differential equations using symbolic
manipulation software available for computers today. Additionally , the student
should acquire an ability to model real world situations in terms of differential

V. Disability Services Policy:

Reasonable accommodations will be made for students with disabilities provided
those students have registered with the Office of Disability Services. Present your
with the documentation.


In the event of a bomb threat, tornado, or fire, students and staff may be asked to
evacuate the building or move to a secure location within the building. Evacuation
routes for movement to an external location or to a shelter within the building are
posted at the front of the room. Students should review the maps and make sure
that the exit route and assembly location for the building are clearly understood. If
you have a disability that may require assistance during an evacuation, please let
your faculty know at the end of the first class.
