Please help. I have no idea what to do with this trig problem.
~~~
Sandra is riding the Ferris wheel, and her height can be modeled by the equation H(t) = 25 cos(pi/14 * t) + 31, where H represents the height of the person above the ground in feet at t seconds.
Part 1: How far above the ground is Sandra before the ride begins?
Part 2: How long does the Ferris wheel take to make one complete revolution?
Part 3: Assuming Sandra begins the ride at the top, how far from the ground is the edge of the Ferris wheel when Sandra's height above the ground reaches a minimum?

what is the value when t=0?

cos has a normal period of 2pi
so when does pi/14 * t = 2pi?

I know that a full revolution around the unit circle is equal to 2pi
