How do I do part A?

5. (6 pts.) A Ferris wheel with a radius of 50 feet, with a center that sits 60 feet above the ground, turns at a rate of 2 revolutions per minute. That means it completes one full turn in = of a minute, so its period is = minute. One formula for the height above ground 2 of a rider on this Ferris wheel is: H(t) = -50 cos(4nt) + 60. H(0) (a) Write a formula for H(t) using a sine function instead of a cosine function. (Note: The rider should still start at the lowest point on the ride at time ( = 0.) 60 0.25 0.5 0.75 1 1.25
