Melchior1905 0 Report post Posted October 3 Hello, I've just begun writing my standard level mathematics internal assessment. My topic is about waves and tides, where what I will be doing is gathering tides data from different locations in Hong Kong and then try to find the best sine/cosine function that will fit this gathered data. With this I will be able to predict tide hours and height but I am not sure this is a good enough topic to pursue in terms of the mathematics, does anyone have any idea how to make this a more difficult IA or add depth to the subject? help would be very much appreciated...
