4.1.1 Getting off to a good start You may find it useful to plan the way you will start your exam. Having a routine can be calming when under pressure. This is from a student who recommends a checklist:
I have a mental checklist of what I need to do once I've turned over the paper. I do this because I used to rush in and answer the fir 1.1: Converting to component form In some applications of vectors there is a need to move
backwards and forwards between geometric form and component form; we
deal here with how to achieve this. To start with, we recall definitions of cosine and sine. If
P is a point on the unit circle, and the line segment
OP makes an angle θ measured anticlockwise
from the positive x-axis, then
cos θ is the x-coordinate of
P and sin θ is the
y-coordinate of P ( Westward Expansion Overview 1.2.7 Summary What we must do to understand numbers as they are used as evidence in social science is to practise and so become familiar with them, and to understand the conventions which determine how they are used. Sets of numerical data can be presented in many ways, as tables, bar charts, pie charts or line graphs. These are just different ways of trying to represent or make a picture of numbers. Which is used is largely a matter of which best shows 2.2 Tables and percentages Tables often give information in percentages. The table below indicates how the size of households in Great Britain changed over a period of nearly 30 years. 3.6.1 Saying thank you and acknowledging current contribution Probably the single most important way of retaining people's support and goodwill is to say thank you promptly and to demonstrate that you have noted and valued whatever it is they have contributed. If you do not have the systems to guarantee that supporters are thanked appropriately, then you cannot seriously expect to move anyone anywhere – be it up a pyramid, into a kite or round a matrix. 18.024 Multivariable Calculus with Theory (MIT) 1.5 Models of health care delivery In the quest to understand health and illness behaviour, social and medical researchers have developed various models to explain the different forms of health care delivery. These models emerged because, in the mid-20th century, social researchers began to question not only the position of professions in western countries but also the relationship between professionals and users. Early explorations of the patient's role in health care suggested that it was fairly prescribed (Parsons, 1951), a How a Rainbow Works L'Esthétique et l'art du point de vue d'une anthropologie complexe (2/3) (audio) Cycle de conférences Edgar Morin : Globalité et complexité (2/3) Organisé par le Collège d'études mondiales et la Fondation Calouste Gulbenkian.

This unit will help you to analyse the relationship that exists between developed and developing countries under the World Trade Organization regime of Development Round negotiations. The current world trade regime has a very mixed record in promoting growth and reducing poverty. This material is from our archive and is an adapted extract from Making the international: Viewpoints, concepts, and models in international politics and economics (DU321) which 3.5 Meaning and language-based methods In recent years many psychologists have become interested in language as an important human ‘product’ (the symbolic data described in Section 2.3 above). There are various ways in which psychologists analyse conversations, data from interviews and written texts. One of the most popular methods is content analysis 1.1 Policy delivery The question of policy delivery seems to be growing in importance. So, for example, the Blair governments in the UK were, from the outset, preoccupied with ‘delivery, delivery, delivery’ as ministers and prime minister grew increasingly frustrated with what was often viewed as the intransigence of public service professionals. The constant cycle of change, in which new policies and initiatives were introduced in rapid succession, producing what critics described as ‘policy overload’ o Toxic Inequality in the United States: economic inequality and racial injustice driving ugly politic 5.1 The interview as a selection method: pros and cons Traditionally, the interview has been the main means of assessing the suitability of candidates for a job. Almost all organisations use the interview at some stage in their selection process. Similarly, most applicants expect to be interviewed. Interviews are useful for assessing such personal characteristics as practical intelligence and interpersonal and communication skills. The interview can be used for answering applicants’ questions, selling the organisation and negotiating terms and 3 The water table The water table is a fundamental reference surface in the study of groundwater. It tends to follow the ground surface, rising under hills and falling at valleys, but the gradient of the water table is usually much less than that of the ground surface (Figure 4). Under hills the water table is usually at greater depths below the surf Introduction The versatility of mammals is a central theme of the 'Studying mammals' series of units, but surely no environment has tested that versatility as much as the rivers and oceans of the world. Mammals are essentially a terrestrial group of animals, but three major groups have independently adopted an aquatic way of life. In moving to the water, aquatic mammals have had to survive, feed and reproduce using a set of biological characteristics that evolved in association with life on land. This cou

This course is a continuation of 18.014. It covers the same material as 18.02 (Multivariable Calculus), but at a deeper level, emphasizing careful reasoning and understanding of proofs. There is considerable emphasis on linear algebra and vector integral calculus.
This video shows how sunlight goes through raindrops and is separated into the colors we see in the rainbow. Good explanation on how the eye sees the rainbow. (03:17)
In the video, the instructor explores the proof of the trig identity sin(a+b) = (cos a)(sin b) + (sin a)(cos b). In an easy conversational tone, the instructor uses the computer screen as his 'blackboard' and different colors to emphasis his points. For high school students.

Before the Industrial Revolution everything was produced by hand. Beginning in the 19th century, advances in manufacturing revolutionize the American way of life. A man named Samuel Slater memorized the plans for factories and brought them over to America. This started up the Industrial Revolution in America. Americans began moving into cities to work in factories. Assembly lines started appearing in factories which led to unskilled workers like women and children working. (2:31)
