NEED HELP EXTREMELY!!!!
Travis is riding the Ferris wheel at the amusement park. His height can be modeled by the equation H(t) = 22 cos (pi/13t)+ 28, where H represents the height of the person above the ground in feet at t seconds.

Part 1: How far above the ground is Travis before the ride begins?

Part 2: How long does the Ferris wheel take to make one complete revolution?

Part 3: Assuming Travis begins the ride at the top, how far from the ground is the edge of the Ferris wheel, when Travis' height above the ground reaches a minimum?
