1.  You have all of class to work on your trigonometric function graphs.  Begin working immediately.  Stay in your assigned seat until after Mr. Szwast has checked your homework.  You can use the Table feature on your TI-83 to help you fill out the table on the back.

2.  A man is standing at the top of a cliff, 25 meters above the water below. He is looking out at a boat in the distance. The angle of depression is 30˚. 1) How far away from the bottom of the cliff is the boat? 2) How far away is the boat from the man?

4.  No calculators  No notes  No talking. If you appear to be talking while any quiz is out, you will receive a zero.

5. Section 4.4

6.  We are no longer restricting ourselves to points on the unit circle.  Points can now be any distance “r” away from the origin  Points are still always on the terminal side of θ. Initial side is still the positive x-axis.

20.  Given that and find the value of the rest of the trigonometric functions

22.  We like dealing with acute angles (0˚<θ<90˚).  We can often find trig functions of non-acute angles by using an acute reference angle  Let θ be a non-acute angle in standard position that lies in a quadrant (not on an axis)  Its reference angle is the positive acute angle θ’ formed by the terminal side of θ and the x-axis

25.  Quadrant I:  Quadrant II:  Quadrant III:  Quadrant IV:

26.  Find the reference angle θ’ for each of the following angles:

29. 1) Find the associated reference angle, θ’ 2) Find the trig function value of θ’ 3) Use the quadrant which θ lies in to choose the appropriate sign to the value found in step 2
