__**2/7/12 Amplitude and Period Tutorial**__ If you are having difficulty calculating amplitude and period for the various graphs, click on the link below to help. __**1/17/12 Unit Circle Review Questions**__ Directions: Below is a list of sample questions with answers. These questions would mirror the type of question you would see on your quiz tomorrow. You will also have to fill out the circle with degrees, radians, and (x, y) coordinates for each special angle on the circle. There MIGHT be some bonus questions about what we discussed with the sine curve so far....Also, the projector in my room will NOT turn on, so I can't film the video. Work out the problems below as practice. If you need help, you can always view the original video from 1/12/12.

1) Evaluate the cosine of 2pi/3. (Answer: -1/2)

2) Find the 6 trigonometric functions of 7pi/6. (Answer: cos = -sqrt3/2, sin = -1/2, tan = sqrt3/3, sec = -2sqrt3/3, csc = -2, cot = sqrt3)

3) Evaluate the sine of 21pi/4. (Answer: -sqrt2/2)

4) Find a positive angle coterminal with -7pi/2. (Answer: will vary, but possibility would be pi/2)

5) Find the reference angle for 13pi/6. (Answer: pi/6)

__**1/12/12 Unit Circle Assignment**__ Directions: Answer these questions on the back of the unit circle you were provided with in class today. If you need a refresher, view the video below for a quick review of the unit circle and its functions!

1) Evaluate the tangent of 7pi/4.

2) Find the sec 7pi/6.

3) Find the cosine of 21pi/4.

4) Find the sine of 13pi/3.

5) Find 2 angles coterminal with 2pi/3.
