| Footage description: | Norman Gowar introduces the programme and gives several examples of functions as used in everyday life. He uses the cost of sending letters, the height of a point when rotated through an angle, and the conversion of degrees Fahrenheit to degrees Centigrade. Roger Duke expands the idea of function to include the concept of it being a process the raw materials of which are called 'domain', the end product of which is called the 'Co domain'. Roger Duke now takes a closer look at the function for temperature conversions which can be expressed as t -- 5/9 (t-32). He then shows how this function can be depicted on a graph, as can the other functions for example the sine-finction. Norman Gowar explains how functions can be seen as objects in themselves, which can be manipulated. He then shows how functions can be combined to generate composite function. Credits. |
