N1  - Includes index; Chapter 1. First order differential equations -- Chapter 2. Linear second order differential equations -- Chapter 3. Elementary numerical methods -- Chapter 4. The laplace transform -- Chapter 5. Linear system of differential equations -- Chapter 6. Non constant coefficient second order linear equations and series solutions -- Chapter 7. Nonlinear differential equations -- Chapter 8. More on numerical methods
N2  - This text is based on a course, successfully given at the University of New Mexico for the last eight years, which is a one-semester introduction to ordinary differential equations for mathematics majors, engineering students, and majors in the physical sciences. It differs from the traditional introductory course in that numerical methods are used throughout as a tool to analyze the qualitative behavior of solutions as well as to approximate them
