1.4 Intersection of two lines Two arbitrary lines in
2 may have a single point of intersection, may be parallel, or may coincide. The first two possibilities are illustrated below. Can we tell from the equations of the lines which of the three possibilities occurs?Author(s):
1.3 Parallel and perpendicular lines We often wish to know whether two lines are parallel (that is, they never meet) or perpendicular (that is, they meet at right angles). Two distinct lines, y = m1x + c1 and y = m2x + c2, are parallel if and only if they have the same gradient; that is, if and only if m1 = m2. For example, the lines y = −2x + 7 and
1.2 Lines The equation of any line in Learning outcomes By the end of this unit you should be able to: Section 1 recognise the equation of a line in the plane; determine the point of intersection of two lines in the plane, if it exists; recognise the one-one correspondence between the set of points in three-dimensional space and the set of ordered triples of real numbers; recognise the equation of a plane in three dimensions.

These work by allowing you to set up a profile once you have registered on their site, and when there are items meeting your criteria you receive an email. The good thing about alerts is that you don't have to do anything once you have set up your profile. The downside, particularly with alerts services from the search engines, is that given the extent to which internet traffic is on the increase whether new web pa Season 3 – Lesson 08 – Coffee Break Spanish In episode 8, Alba and Mark discuss smoking laws in different countries. Language points covered include the future perfect tense, eg. “I will have stopped smoking”, the use of soler, and the phrase pillar a alguien desprevenido. José’s intermedio covers two phrases which you can use to describe how well you speak Spanish. Please note that lesson 08 of Season 3 was originally known as lesson 308 of Coffee Break Spanish. We have ren 1 Wave energy The energy carried by ocean waves derives from a proportion of the wind energy transferred to the ocean surface by frictional drag. So, ultimately it stems from the proportion of incoming solar energy that drives air movement. Just how much energy is carried by a single wave depends on the wind speed and the area of ocean surface that it crosses; wave height, wavelength, and therefore wave energy, are functions of the distance or fetch over which the wind blows. Not surprisingly the ma 9.2 Lennox Castle Hospital This course looks at the history of institutions in the twentieth century, starting with a case study of Lennox Castle Hospital. It tries to make sense of the history of Lennox Castle, and of institutional life in general, through testimony of those who experienced institutions as inmates and as nurses, as well as through Erving Goffman's model of the ‘total institution’. It examines the social bases of segregation, the professionalisation of staff in asylums and institutions, and campaig 2.5.1 Homologous series Another approach to the problem is to consider what happens to the properties of a related series of compounds of increasing chain length. The simplest precedent is the sequence of properties for the saturated paraffin hydrocarbons (normal alkanes). Such a series of compounds is known as an homologous series. The lowest members are gases like methane and ethane, but as the length of the chain increases the hydrocarbons become first liquids and then waxy solids.
