Elementary Methods for Ordinary Differential Equations of First Order,Whenever one seeks to analyze mathematically a problem arising in the “real” world, the first order of business is the selection of a mathematical “model” or formulation for the problem. That is, one must choose or invent some mathematical problem to represent the real problem.

The Linear Ordinary Equation of Order n,The examples in Chapters I and II have introduced special methods for finding exact solutions of some special equations. Generally speaking, the discovery of exact solutions of a differential equation (when this is possible) does depend upon the use of ad hoc methods or tricks, often requiring considerable ingenuity.

Linear Ordinary Differential Systems,The study of a system of linear differential equations (or a linear differential system) of the form . is generally simplified with the aid of matrix theory. Moreover, matrix methods can often give useful information about differential systems which are not quite linear.
