The Canadian National Historic Windpower Center, at Etzikom, Alberta, has various styles of windmills on display. The tip of the blade of one windmill is at its minimum height of 8 metres above the ground at a time of 0 seconds. Its maximum height is 22 m above the ground. The tip of the blade rotates 12 times per minute. a) Write a cosine function to model the rotation of the tip of a blade in the form h = a cos[b(t t - c)] + d, where a > 0. Assume that when O the tip of the blade is at its minimum height. Show and explain how you obtained a, b, c and d. b) What is the height of the tip of the blade after 6 seconds, to the nearest hundredth of a metre? c) For how long is the tip of the blade above a height of 16 metres in the first rotation, to the nearest hundredth of a second? You may use your graphing calculator to determine this. Explain how you used your graphing calculator.
