6.1 Defining amplitude

Another important property of a sine wave we need to be able to specify is its amplitude. In essence, the amplitude of a sine wave is its size. Unfortunately there are various ways of defining what is meant by the size of a sine wave, and you are likely to come across many of them in material you look at outside this unit. Before I explain what our definition is, it will help matters if we look at what is meant by the average value of a sine wave.

1.6.1 The example

Suppose that a couple who have children are thinking about the next family holiday. They list five options, including staying at home. They also list four criteria and they give each an importance weighting on a scale of 1 to 5, where 5 is the most important and 1 is the least important.

3.5 Distinctions about systems practice

A tension has existed throughout the history of Western thought around whether to focus on parts or the whole. The practice that springs from this history carries the same tension. This tension has been particularly visible within science and philosophy for a long time and it gives rise to different approaches. I will be addressing these tensions in Author(s): The Open University

1.5.3 Angular magnification

You may be familiar with the scales that appear on terrestrial maps or images obtained with microscopes, possibly stated as 1 : 100 000 or 1 mm corresponds to 1 μm. Scales such as these indicate how the size of the reproduction compares to the real thing. Image scales are no less important in astronomy, though they are usually stated in a different form, as we now explain. Imagine for a moment that you have the use of a telescope that allows you to observe Saturn and its ring system. It must

Introduction

People have always communicated with each other – initially by face-to-face communication through gestures and sounds, then over a distance through written messages and signals in the form of fires, lights or flags. Technology, for instance in the form of electrical signals, has reduced many of the limitations of distance. Communication networks have become very important, and modern society depends on them for the smooth operation of economic and social activities. In this unit we regard a

The Revolution in the Cotton Industry
This video is accompanied by text. "In the late eighteenth century, a recent Yale graduate named Eli Whitney had aspirations of practicing law. However, like many modern college graduates, Whitney had a debt to repay for his education. To that end, Whitney left his home in Massachusetts to take a tutoring position on a Georgia plantation.
Whitney found himself in the midst of an active agricultural economy. Tobacco, rice, and sugar were vital crops, and cotton cultivation was showing great

5.4.2 The main body of the interview

Your main objective is to gather information. A practical target is to expect the candidate to talk for 70 per cent of the time. Example 2 describes the kind of conduct to avoid when interviewing.

3.19 Practical examples of negative numbers

Negative numbers occur in financial matters, in temperature or height measurements and many other practical situations.

3.4 Monitoring progress

Monitoring progress is about keeping track of what you are doing and how well you are doing it as you work towards your targets. It is about being able to make an assessment about yourself and being ‘self aware’ about your own capabilities, how you learn best, things that have helped you and so on. One problem in becoming more aware of yourself and making a self-assessment is that you may not know enough terms to describe yourself. Think of the first time you were asked to describe a pain

4.3.4 Monitor and critically reflect on your use of communication skills

You need to know how to track and record your progress on your use of communication skills. Try to assess the overall quality of your written and oral work and the way you produced the work. Checklists and criteria provided as part of the project or assignment and those set out in the Bookmark can be very useful tools in helping you to assess for yourself precisely what you are doing and how well you are doing it. Unless you know what you are doing wrong, it is very difficult to improve.

2.5 The emperor

With Napoleon's coronation as emperor in 1804, a new type of official image was once again required. Portraits of the emperor in his ceremonial robes were commissioned from several established artists; these all revived a traditional type of royal portraiture from the eighteenth century. The example shown in Plate 10 is by a former David student, Francois Gérard (1770–1837), by now a fashionable portrait painter (see Author(s): The Open University

2.2 Language and shopping

The concept of self-service has reduced the use of spoken language dramatically, and nowadays shopping transactions may involve no more than the exchange of a few words. However, uses of literacy in shopping are probably increasing, as the next Activity shows.

3.8 Evaluating strategy and presenting outcomes

By now you will have found out about and sampled different resources for learning and used different ways to learn. But the structured approach used in this section is one of the main resources for developing and improving your other key skills.

So how do you know if you have learned? How do you know if you have improved? How do you know if you are meeting the standard for improving your own learning and performance expected of someone doing a course in higher education or using higher

1.4.3 It's all down to connections

For Iris Marion Young, the responsibility of those in North America and Europe towards distant others does indeed rest with their connections to injustices elsewhere, but it would be a mistake to stretch this line of reasoning too far. Although these connections, whether as a consumer, boardroom executive or shop manager, can establish a line of responsibility, as was claimed in Section 3.1, for Young this is only the starting point and not the end point of our involvement.
