課程概述 |
We begin studying ordinary differential equations by deriving them from physical or other problems (modeling), solving them by standard methods, and interpreting solutions and graphs in terms of a given problem. The simplest ordinary differential equations, called ODEs of the first order are to be initiated. In the second chapter we discuss linear ODEs of the second order. This chapter includes the derivation of general and particular solutions. Then we extend the concepts and methods for linear ODEs to orders more than 3. In chapter 6 we consider the Laplace transform and its application to engineering problems involving ODEs. The Laplace transform is a powerful method for solving linear ODEs and corresponding initial value problems without first determining a general a general solution.

It is expected that the students be acquainted with solid knowledge of basic principles, methods, and results, and a clear view what engineering mathematics is all about, and that it requires proficiency in all three phases of problem solving: • Modeling, that is, translating a physical or other problem into a mathematical forms, into a mathematical model; this can be an algebraic equation, a differential equation, a graph, or some other mathematical expression. • Solving the model by selecting and applying a suitable mathematical method, often requiring numeric work on a computer. • Interpreting the mathematical result in physical or other terms to see what it practically means and implies.
