Ordinary Differential Equations

In applications, we are often faced with the problem of determining a function f given information on some of its derivatives. A typical example would be to find the position of a particle as a function of time, given its velocity as a function of time and position. Such a formulation of a problem is called a differential equation. The general form is an equation which involves f and some of its derivatives. The study of such equations is a major area of mathematics and it is not always possible to obtain an exact solution. Here we consider only a few simple types where we can obtain a solution using the techniques on integration developed in Chapters 14 to 16. Our results give a flavour of the subject, ...
