This is a mathematical modelling activity under the topic of periodic functions (trigonometric functions)
The objectives are
1. To find the appropriate trigonometric function that can represent and model the relationship between two variables in a given set of data,
2. To apply the knowledge of amplitude, period and axis of the curve of trigonometric functions, and to use ICT tools, to facilitate the modeling and
mathematical problem solving.
