The aim of 16-19 Mathematics has been to produce a course which, while challenging, is accessible and enjoyable to all students. The course develops ability and confidence in mathematics and its applications, together with an appreciation of how mathematical ideas help in the understanding of the world and society in which we live. This unit develops: * an appreciation of possible errors which may arise from computer calculations and the need for more subtle methods to improve accuracy; * a critical faculty in considering numerical calculations and interpreting results; * an awareness of the use of the computer and/or graphical calculators in carrying out numerical algorithms and helping in the visualisation of the process; * an ability to use appropriate technology to solve problems numerically.
