In Part C you have learnt that:

• accurate law reporting allows for legal principles to be collated, identified and accessed;

• there are many sources of law reports: Year Books (1275â€“1535), private reports (1535â€“1865), modern reports (1865 to present), the Law Reports, Weekly Law Reports, All England Law Reports, legal periodicals and newspapers, European Community Reports, DVD-ROMs and legal databases available via the internet.

The data set in Table 7 (section 1.8) comprised non-numerical or categorical data. Such data often appear in newspaper reports and are usually represented as one or other of two types of graphical display, one type is called a pie chart and the other a bar chart; these are arguably the graphical displays most familiar to the general public, and are certainly ones that you will have seen before. Pie charts are discussed in section 2.2 and bar charts in section 2.4. Some problems

Another useful property to remember is that one complete turn is 360Â°. This means that when there are several angles making up a complete turn, the sum of those angles must be 360Â°.

For instance, if the angles turned by a Big Wheel at a fairground as it picks up passengers were Î±, Î², Î³ and Î´ as shown in the diagram below, then Î± + Î² + Î³ + Î´Â =Â 360Â°.

## SAQ 26

Find the distance between the numbers 2 âˆ’ i and 1Â +Â 3i.

Author(s): The Open University

The modulus function provides us with a measure of distance that turns the set of complex numbers into a metric space in much the same way as does the modulus function defined on R. From the point of view of analysis the importance of this is that we can talk of the closeness of two complex numbers. We can then define the limit of a sequence of complex numbers in a way which is almost identical to the definition of the limit of a real sequence. Another analogue of real analysis arises

Proportion is another way of expressing notions of part and whole. You might say that the proportion of village inhabitants who are children is a quarter, or that the proportion of fruit juice in the punch is two thirds, or that the proportion of sand in the concrete is three quarters.

All these examples involve the fractions Author(s): The Open University

The doâ€“talkâ€“record triad (DTR) is a description of what is likely to take place in collaborative mathematics classrooms. It is concerned with observable events, and with the learner rather than the teacher, though many teaching insights flow from it. Although the order of the triad suggests that it should be followed in a particular sequence, this is not necessarily the case. Sometimes talking comes before doing or recording before talking. It also takes time for a learner to move

## Task 10 The MÃ¶bius band

Take a long thin strip of paper (preferably squared or graph paper) about 30 cm by 3 cm. Give one end a half twist and then tape it together. This is a MÃ¶bius band as shown in Author(s): The Open University

School mathematics curricula often focus on lists of content objectives in areas like number, arithmetic, statistics, measurement, geometry, trigonometry, and algebra. A typical list of content objectives might contain over one hundred objectives to be introduced or revisited and learned each year. These can be seen as hierarchical in nature but many textbooks do not attempt to organise the objectives in ways that enable the bigger underpinning ideas to become apparent to the pupils. In addit

The so-called â€˜content/processâ€™ debate in mathematics involves discussion of the relative importance of content and process in mathematics. It originated as part of a discussion about the nature of mathematics, particularly of school mathematics, and of the purposes for which mathematics is learned. Identifying content and process in mathematics draws attention to the idea that mathematics is a human activity.

Culture and Climate Change
Every generation faces challenges that previous generations could scarcely imagine. Twenty years ago, few people were talking about climate change, now it's one of the most hotly-contested areas in politics. How do artists, writers, musicians and broadcasters respond when a new subject appears that is as large and significant as this? What kind of novels, plays, paintings, sculptures, movies and music begin to emerge?Author(s): The OpenLearn team

Future energy demand and supply
When you consider that the global annual consumption of primary energy increased more than ten-fold during the 20th Century, the importance of planning future energy supply becomes clear. Future energy demand and supply is a free course that offers an introduction to how this is being undertaken. First published on Tue, 04 Dec 2018 as
