Pre-cal 12 Question!
Sinusoidal functions!

A Ferris wheel ride can be represented by a sinusoidal function. A Ferris wheel has a radius of 15 m and travels at a rate of six revolutions per minute. Lucy boards the ride at the bottom char from a platform 1m above the ground.

Determine the equation of a cosine graph in the form of

h(t) = a cos [b (t - c)] + d

Please help me to find value of d.

This is what I know.

amplitude or a = radius of circle
a= 15 m

c= 0 No phase shift

p = 60sec/10 = 10 sec

I don't understand what is the value of d???

d means vertical shift or transfer.
