Question

# The height above the ground of a rider on a Ferris wheel can be modelled by the sine function h(x) = 25

sin(x – 90°) + 27, where h(x) is the height, in metres, and x is the angle, in degrees, that the radius to the rider makes with the horizontal. Show on the table for one revolution of the Ferris wheel as follows:

Then predict and explain the values for a second revolution of the Ferris wheel.
