Using the cubic model given for the new position of the coastline: Remaining area = 3442 m2, approximately 3400 m2 The loss of land is approximately 4877 – 3442 =1435 i.e 1400 m2 (to 2 sf) If you have a graphic calculator, use it to find a cubic model for the position of the coastline after 20 years. Integrate the function to estimate the remaining area and the loss of land. Compare your results with the estimates given above. Think about Simplify the integration of the two functions by combining them into a single function, containing only 4 terms. Integrate this function and evaluate it over the interval 0 to 100. Do you get the same result as that above? Try these In each case, use either Excel or a graphic calculator to find a quadratic or cubic function that best fits the data. 1 The coordinates give the position of a coastline, with offsets from the x axis, at intervals of 10 metres. a Find the area of land represented by the area between the curve and x the axis. b If the coastline recedes at an average rate of 1.8 metres per year,
