First-order differential equations

This unit introduces the topic of differential equations. The subject is developed without assuming that you have come across it before, but it is taken for granted that you have a basic grounding in calculus. In particular, you will need to have a good grasp of the basic rules for differentiation and integration.

This study unit is an adapted extract from the Open University course MST209 Mathematical methods and models, which is no longer taught by the University. If you want t

La médecine et la négation de la mort (video)

Didier Sicard évoque les différents aspects de la mort, comme la mort évacuée, celle des autres. La mort est absente du cursus universitaire, elle fait d'ailleurs fuir les étudiants. La mort est un tabou et l'hôpital est un lieu où la mort est escamotée. Les soins palliatifs qui sont en régression en 2005 posent aussi parfois le problème du respect de l'intimité du patient avec la mort.

5.2 The equations of uniformly accelerated motion

Equations 22, 23 and 24 provide a complete description of uniformly accelerated motion. By combining them appropriately, it is possible to solve a wide class of problems concerning the kinematics of uniformly accelerated motion. Nonetheless, those particular equations are not always the best starting point for the most common problems. For example, it is often the case that we want to know the displacement from the initial position after some specified period of constant acceleration, rather

Introduction

Social scientists collect evidence to support their claims and theories in different ways. Such evidence is crucial to the practice of social science and to the production of social scientific knowledge.

You may be aware of the idea of active reading, which is about reading with the aim of understanding and grasping something: a definition, an argument, a piece of evidence. What that suggests is that active reading is about reading and thinking at the same time. In

2.1.1 Ron revisited

In Case Report 1 you met Ron. Ron is 59 years old, has a BMI of 31 and a central obesity ratio of 0.96, indicating that he is moderately obese, with the fat concentrated in his abdomen, rather than his hips. Clearly a number of factors, some environmental, others relating to Ron's age and all interacting with Ron's genetic constitution, may help to provide an explanation. Let's look at some of these factors in a little more detail. It is clear that Ron enjoys a comfortable lifestyle with litt

3.4 What has any of this to do with computers?

Human beings invented computers because we have a compelling interest in data. We seek to turn our perceptions of sensations into symbols, and then to store, analyse, process, and turn these symbols into something else: information. Modern computers, with their enormous storage capacity and incredible processing power, are an ideal tool for doing this. They allow us to acquire data, code it in terms of signs, store, retrieve, or combine it with other data. Sophisticated o
