This is an introductory course about basic ideas and methods
for ordinary differential equations and their applications.
We are particularly interested in developing skills to 
read and study  the
textbook.  Not all material will be presented in class.  
We will expect you to
acquire some of the material.  Our responsibility is to 
point out where you
should concentrate your study and to help pace your 
progress through the course.  


We will also use the software package Maple to explore 
solutions of differential equations.
