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.

A tried and true cartoon format, the Schoolhouse Rock songs were a favorite in the 70's and 80's. This one gets kids singing about the definition and proper use of adverbs with loads of examples. An adverb is a word that modifies a verb, adverb, or adjective.  (3:00)

In Section 3 we consider how to sketch the graphs of more complicated functions, sometimes involving trigonometric functions. We look at graphs which are sums, quotients and composites of different functions, and at those which are defined by a different rule for different values of x.

Identification of specifically European traditions, such as that of a European system of values, is no easy task. Europe arrogated the Christian faith to itself, but it was hardly in Europe that it originated and the practice of Christianity has never been restricted just to Europe. Modern Europe also identified itself with traditions of civilization, progress and a general superiority over other cultures and peoples, although European practice and the ends to which its growing power was put

3.A27 Case Studies in Forensic Metallurgy (MIT)
TV programs such as "Law and Order" show how forensic experts are called upon to give testimony that often determines the outcome of court cases. Engineers are one class of expert who can help display evidence in a new light to solve cases. In this seminar you will be part of the problem-solving process, working through both previously solved and unsolved cases. Each week we will investigate cases, from the facts that make up each side to the potential evidence we can use as engineers to expose

Many inventors have said that having the idea for an invention is the easy part. This is often demonstrated by the frequency of examples of simultaneous invention. At one exhibition of inventions I attended there were three separate portable ladders to escape from fires, two systems for using rainwater to flush toilets, two types of portable vehicle wheel clamp, and two methods of reducing red-eye in flash photography. In most cases of technological innovation only one of the competing techno

The Impact of 3D Digital Modeling on the 3D Design Aspects in Urban Design Plans
Some experts suggest that urban design plans in US cities may lack adequate coverage of the three-dimensional design aspects of the built environment. 3D digital models may help designers visualize and interact with design alternatives, large urban data sets, and 3D information more effectively, thus correcting this problem. Case studies of recent urban design plans that have used 3D digital models may indicate whether these technologies can increase the quality of the plan. This research discus

Arrangements for care and support which people manage for themselves or have organised for them privately or informally tell us something about the shifting borders between funded and non-funded care, between health and social care, and between paid and unpaid care work. They also demonstrate how the reality of the mixed economy of care is played out in the arrangements which people make for care and suipport in their own households.

As you noticed on the town plan, street names in France and other French-speaking countries often commemorate famous people and historical events. In most French towns, you will find, for instance, rue/avenue/place/boulevard du GÃ©nÃ©ral de Gaulle or de la RÃ©publique or du 14 juillet (anniversary of the storming of the Bastille, which started the French Revolution).
