Introduction to differentiation
This free course is an introduction to differentiation. Section 1 looks at gradients of graphs and introduces differentiation from first principles. Section 2 looks at finding derivatives of simple functions. Section 3 introduces rates of change by looking at real life situations. Section 4 looks at using the derivative of a function to deduce useful facts for sketching its graph. Section 5 covers the second derivative test, used to determine the nature of stationary points and ends by looking a

Introduction

Many people have the impression that underground water occupies vast caverns, such as those in the Derbyshire Peak District, flowing from one cavern to another along underground rivers. This is a common misconception: underground caverns are fairly rare, but huge quantities of water exist underground, within rocks. This is because many rocks contain pores, spaces that come in all shapes and sizes. In sediments, and consequently sedimentary rocks, there are often pores between grains which can

1.2.2 Summary

  • The results of successive editions of the Eurobarometer show that in most EU countries only a very small percentage of people, around 5 per cent, declare having an exclusive European identity, while up to 50 per cent do not have any sense of European identity.

  • European political identity is weak and there is a great variation across states.

5.7.2 Elimination of pathogens through solar disinfection

The lack of safe drinking water in many developing countries has prompted research into simple methods of disinfecting small quantities of water. One such investigation at the University of Beirut in the Lebanon revealed that 99.9% of total bacteria in a water sample could be destroyed by 300 minutes exposure to direct sunlight. In effect this means that if you left a sample of water in a translucent container, a lot of the bacteria in it would be killed.

Research to date has concentrat

5.1 Managing relationships

You should now understand that markets and the customers within them are the responsibility of all managers within an organisation. An organisation needs to identify what will create extra value for its customers, and design a value-driven operating system that will concentrate all its efforts on producing it. This process of going to market involves the organisation in managing the relationships between itself and its customers and competitors, and also in the co-ordination of the organisati

1.2.4 Stage 2: Find a way in

It's easy to be distracted by the surface appearance of a diagram, but we are really interested in the underlying message. This is rather like the distinction made between the content and context reading of photographs. Once you are sure that you know what the main heading means, focus on a particular element and think it through. If it is a bar chart, for instance, pick on one of the bars and tell yourself what it represents, what it is telling you. Is it showing a percentage or a total? Wha

10 Course summary

The course began by considering what factors contribute to individual differences. The case was made, with the spiders, and later with genetic diseases, that the genome was very important. Subsequent sections revealed that the external environment (e.g. maternal care, the presence of light) and the internal environment (e.g. hormones and drugs) were very important and that they can both shape and determine the development of the organism. Environmental factors, in the form of hormones and dru
