Description of the extract

The following extract is Section 5, Vectors, of Unit 5, Coordinate geometry and vectors, which has seven sections in total and is scheduled to be started after about two months' work on the module – see the study schedule for details. This section is expected to take about four hours to study, plus additional time on the corresponding assignment questions. The whole of Unit 5 is scheduled to take about 16 hours to study, spread over two weeks.

This extract, which considers how quantities that have both a size and a direction can be represented, is relatively self-contained and should be reasonably easy to understand for someone who has not studied any of the previous texts in the module. A few techniques and definitions taught earlier in the module are present in the extract without explanation. However the extract isn't entirely representative of the module materials because there are no explicit references to some module components, such as software. In this extract some illustrations have been removed due to copyright restrictions.

The extract is a small part (probably around 1%) of a large module that is studied over about eight months and so can give only an approximate indication of the level and content of the module.

The first document below contains the main extract which is on pages numbered 34 to 54. The second document contains solutions to the activities and exercises in the extract. (Solutions to activities and exercises are provided at the back of each printed MST124 unit.)
