Coming up in this lesson:

In this weekâ€™s lesson, Mark and Alba talk about music. Their discussion includes talk of playing musical instruments and how listening to music is changing because of technology. In the intermedio, JosÃ© provides a couple of interesting phrases which can be used to say that you find something difficult. Language points covered include comparitives such as tan â€¦ como and tanto â€¦ como, avoiding the subjunctive and a particular use of verbs which dif

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 Î¸ measured anticlockwise from the positive x-axis, then cosÂ Î¸ is the x-coordinate of P and sinÂ Î¸ is the y-coordinate of P (

I now want to take forward the notion of a science curriculum for public understanding, identifying problems and opportunities. Our guide in what follows is the Beyond 2000 document, which emerged from a working group led by UK-based science educators, working collaboratively with science teachers, education researchers, professional scientists within unive

• 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

Look at Figure 9. Start with the map distance on the horizontal scale, move vertically up until you reach the line, then move horizontally until you reach the vertical axis. The number at that point will give you the corresponding ground distance in kilometres.

Working with dilemmas
Dilemmas are part of the fabric of organisational and individual life; these are often presented as the choice between two (or more) equally compelling propositions. In this free course, Working with dilemmas, you will focus on how to address dilemmas effectively. In particular, you will explore the extent to which dilemmas are or should be treated as choices between two extremes, and how the response to and resolution of dilemmas can move beyond binary choices to the reconciliation of opposites

1.018J Fundamentals of Ecology (MIT)
This is a basic subject in ecology that seeks to improve the understanding of the flow of energy and materials through ecosystems and the regulation of the distribution and abundance of organisms. The course covers productivity and biogeochemical cycles in ecosystems, trophic dynamics, community structure and stability, competition and predation, evolution and natural selection, population growth and physiological ecology. There is particular emphasis placed on aquatic systems.

2.003J Dynamics and Control I (MIT)
This class is an introduction to the dynamics and vibrations of lumped-parameter models of mechanical systems. Topics include kinematics; force-momentum formulation for systems of particles and rigid bodies in planar motion; work-energy concepts; virtual displacements and virtual work; Lagrange's equations for systems of particles and rigid bodies in planar motion; linearization of equations of motion; linear stability analysis of mechanical systems; free and forced vibration of linear multi-deg

We have seen in Section 2.2 that the complex number system is obtained by defining arithmetic operations on the set RÂ Ã—Â R. We also know that elements of RÂ Ã—Â R can be represented as points in a plane. It seems reasonable to ask what insight can be obtained by representing complex numbers as p

Mammals share a number of biological characteristics that mark them out as members of the class Mammalia. Many of these are adaptations to a life on land. For example:

• Mammals give birth to young at a relatively advanced stage of development and feed their young on milk.

• Most mammals have hair, or fur, covering part or all of the body.

• Mammals have a high metabolic rate and maintain a relatively high and constant body temp
