/ ingonometry 2. A Ferris Wheel ride can be represented by a sinusoidal function. A Ferris Wheel at Westworld Theme Park has a radius of 15 m and travels at a rate of six revolutions per minute in a clockwise rotation. Ling and Lucy board the ride at the bottom chair from a platform one metre above the ground. a) Sketch three cycles of a sinusoidal graph to represent the height Ling and Lucy are above the ground, in metres, as a function of time, in seconds. t 3 cycles seconds 1 min b) Determine the equation of the graph in the form h(t) = a cos [b(t - c)] + d. 30 sec
