	Please answer four of the following five questions.  Good luck and have fun!

1) Graph the equation y = sin θ, for 3 cycles, with points at every 30 degrees

2) What is the principle angle for the point (3, -6)?

3) State the maximum, minimum, period, amplitude, and axis of the curve for each of the following:
a)b)

4) Solve the following (to one decimal place), and draw the unit circle for each, where θ is between 0 and 360 degrees:
a) sin θ = -0.23		b) cos θ = 0.5		c) tan θ = 1.1

5) The vertical distance in metres of a rider with respect to the horizontal diameter of a Ferris wheel is modeled by h(t) = 5 cos (18t)°, where t is the number of seconds.
a) To one decimal place, what is the rider’s vertical distance with respect to the horizontal diameter of the wheel when t = 8s? 16s? 30s?
b) When is the rider first at 4.5 m?, -3.2m?
c) When is the third time the rider is at -2.5 m?
