A differential equation involving derivatives of the dependent variable with respect to only one independent variable is called an ordinary differential equation, e.g., 2 3 2 2 d y dy dx dx + = 0 is an ordinary differential equation .... (5) Of course, there are differential equations involving derivatives with respect to

SAMPLE APPLICATION OF DIFFERENTIAL EQUATIONS 3 Sometimes in attempting to solve a de, we might perform an irreversible step. This might introduce extra solutions. If we can get a short list which contains all solutions, we can then test out each one and throw out the invalid ones.

Introduction to Differential Equations (For smart kids) Andrew D. Lewis This version: 2017/07/17. 2. i Preface This book is intended to be suggest a revision of the way in which the first course in di erential equations is delivered to students, normally in their second yearofuniversity.

and differential equations are one of the most important parts of this language as far as science and engineering are concerned.

A differential equation (de) is an equation involving a function and its deriva-tives. Differential equations are called partial differential equations (pde) or or-dinary differential equations (ode) according to whether or not they contain partial derivatives. The order of a differential equation is the highest order derivative occurring.

What follows are my lecture notes for a first course in differential equations, taught at the Hong Kong University of Science and Technology.

Course in Differential Equations with Modeling Applications, Ninth Edition. In that text the word equation and the abbreviation DE refer only to ODEs. Partial differential equations or PDEs are considered in the expanded volume Differential Equations with Boundary-Value Problems, Seventh Edition.

This concept will enable us to classify these equations still further. DEFINITION. A linear ordinary differential equation of order n, in the dependent variable ...
