Geometry Written Assignment: Graphing the Cosine Function Total Points = 50

In this assignment you be generating the graph of the cosine curve. To this, you should go through the same process we used to generate the sine and the tangent curves.

1. Using your calculator, complete the table below for the function y = cos x. Find the corresponding y- values rounded to the nearest thousandth.

X = (0)- (30)- (60)- (90)- (120)- (150)- (180)- (210)- (240)- (270)- (300)- (330)- (360)-

Y=

X = (0)- (-30)- (-60)- (-90)- (-120)- (-150)- (-180)- (-210)- (-240)- (-270)- (-300)- (-330)- (-360)-

Y=

2. Plot all the points from the table on the graph below. Draw the curve.

3. Answer the following questions:

a. What is the domain?

b. What is the range?

c. What is the y-intercept?

d. What are the x-intercepts?

4. Also, answer the following questions as you compare the sine and cosine curves.

a. How are the sine and cosine curves similar?

b. How are the sine and cosine curves different?

**Although it is expected that you use a calculator to generate the values, your graph should NOT be done with a graphing utility. Be sure to show all points generated and the curve that connects them.

Can someone please help I don't understand this at all and I need it in by the morning help would be highly appreciated please forgive me for asking you to do it rather than study it. It's a big emergency.
