Hi

A ferris wehel of a radius is 18metres one metre off the ground , it takes 120 seconds for the wheel to complete 1 revolution , the height above ground level of aq person taking a ride on the ferris whell follows a periodic function of the form

H=asin(bt+c)+d

Where H is the Height above ground level in metres and t is the time in seconds since the person got on the Ferris wheel

I know a = the amplitude

d= Vertical shift

2pi/b= the period

c/b = the phase shift

I have to fill in a table with that formula for the
t @ 0 30 60 90 120 sec

i know at 0 and 120 it would be 1 and 60 it would 37

But working with that formula i cant get anything close could someone show me the error of my ways

Thanks
