You are watching your friend ride a Ferris wheel whose radius is 40 feet and center at (0,43). When you start watching your friend at t=0, they are at the highest point of the Ferris wheel. You notice the wheel is spinning clockwise at a rate of 120 seconds per revolution. Create a parametric equation that represents your friend's position at t seconds. DO NOT USE A CALCUATOR.
