I have this assignment and I have no idea how to even start please help!!!!
Graphing the cosine function

Answer 1

1.Using your calculator, make a table including x = 0, ten positive x-values (increments of 30 degrees) and ten negative x-values. Find the corresponding y-values.
2.Plot all 21 of these points.
3.Draw the curve.
4.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?
5.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? 1.Using your calculator, make a table including x = 0, ten positive x-values (increments of 30 degrees) and ten negative x-values. Find the corresponding y-values.
