This unit explores reasons for studying mathematics, practical applications of mathematical ideas and aims to help you to recognize mathematics when you come across it. It introduces the you to the graphics calculator, and takes you through a series of exercises from the Calculator Book, Tapping into Mathematics With the TI-83 Graphics Calculator. The unit ends by asking you to reflect on the process of studying mathematics.

10 Summing up

In this course, you have looked at a variety of problems all of which involved using patterns or formulas and you have also extended some of your strategies for solving problems. One of the first steps in tackling any problem is to check that you understand both the problem and the information you have been given. This step can concentrate on what the question means. However, this can also involve looking up or checking on mathematical terms, notation or definitions as in Goldbach's conjectur

4.2 The use of systems analysis in public policy

The application of mathematical techniques to military operations was pioneered in Britain during the Second World War (see Box 7) and became known by a variety of names (Hoos, 1972, p. 42). At the end of the war, the United States Air Force sponsored the application of those techniques and methods to problems of US national security. Funds to investigate the effects of new weapons systems and for the exploration of defence policy issues were allocated to defence contractors. From one of thes

1.7.4: Is a picture worth a thousand words?

This final subsection is an overview of the various modes of mathematical communication used so far, like words, tables and graphs, and diagrams. You may have a preference for one over the others as a way of presenting ideas and of receiving information. However, they can all aid your understanding and communication of different mathematical ideas. So you need to develop your skills in using and interpreting all of them.

11.2 Note taking

Different ways of note taking include:

1. Re-writing:

Here, the rewording of main parts in a course or article is undertaken. The advantage of this method is that you have thought about course concepts and ideas, and put them into your own words. Here you are summarising points and trying to do this concisely. This does not mean copying directly from the text (unless it is a short quotation you have referenced and chosen to illustrate a point).

1.7 Homologies

If homologies could be recognised as such, then the relationships between species could be inferred from their shared homologies. Unfortunately, however, homologies and analogies cannot always be unambiguously distinguished in practice. The risk of confusion is especially great when closely related species are compared, because similarities in their morphology and ecology make the parallel evolution of analogous features in separate lineages quite likely. As with other statements concerning h

Authentic Assessment in the era of Social Media: ideas and applications from Internet Communications
The emergence of Web 2.0-enabled social media online provides a new opportunity to develop assessments that match with, and draw upon students' engagement with online knowledge networking, creating new possibilities for 'authenticity' in assessment. Authentic assessment refers both to the alignment of assessment with the actual outcomes of students' learning, and to the utilisation in assessment of approximations of real-world situations within which knowledgeable activity might take place.

Berger and Luckmann (1967) is a classic text in the development of the social constructionist perspective within the sociological tradition. Burr (1995) offers a very thorough review of the social constructionist perspective, clearly outlining the methods of discourse analysis. Although the book draws significantly on debates within social psychology, it is of wide relevance to the social sciences more generally.

A fundamental requirement for successful innovation is that the invention must work. It mustn't violate any scientific laws and it must be capable of being transformed into a working prototype. In addition to getting the technology to work it must be designed to be easy to use and reliable, attractive, safe and environmentally friendly. It must also be designed so it's capable of being manufactured on a scale that makes it economic to produce and to buy.

Sometimes an idea for an inventi

The basic function of the ATM adaptation layer is to convert the user data supplied by higher layers into 48-byte blocks of data. The ATM adaptation layer is divided into two sub-layers â€“ the convergence sub-layer, and the segmentation and re-assembly sub-layer. The convergence sub-layer provides services to higher layers through a set of protocols, but I do not need to describe these here. The segmentation and re-assembly sub-layer separates the messages from the conve

Here, the conflict is largely between developing country exporters and developed countries that were reluctant to expose their textile producers to cheaper imports. Here too the UR agreement had a proviso to soften its immediate impact, and a loophole that developing countries seem not to have anticipated. In order to enable textile producers in developed countries to adjust gradually to increased import competition, quantitative restrictions were to be phased out over ten years, starting in
