Passengers on a ferris wheel ride access their seats from a platform 5 m above the ground.
As each seat is filled the ferris wheel moves around so that the next seat can be filled. Once
all seats are filled the ride begins and lasts for 6 minutes. The height h m of Isobel’s seat
above the ground t seconds after the ride has begun is given by the equation
h = 15 sin (10t − 45)◦ + 16.5
a) Use a calculator to sketch the graph of the equation for the first 2 minutes of the ride.

i cant seem to graph it on the tinspire CAS calc, what windows settings should i change it to?
