**Steve**, Sunday, December 8, 2013 at 7:33amIf we consider x the angle traveled since getting on the wheel,

h = 16+12sin(x-120)

**Tom**, Sunday, December 8, 2013 at 11:25amThanks Steve, but what is the reason for minus 120 and not plus 120?

**Steve**, Sunday, December 8, 2013 at 11:38amI drew the diagram with the person boarding at -120°. As the wheel turns counter-clockwise, x starts increasing from 0°. Depending on how you set up your diagram, maybe +120° is appropriate.
