Question

What is the period for the graph of y=cos(0)? (Sketch a graph to help determine the answer.)

a.180
b.90
c.360
d.270

Answer 1

c. 360 degrees

Explanation:

Answer 2

We have the following equation:
y = cos (0)
The first thing you should know is that the period of a function is that value for which the function repeats itself.
We have then:
y = cos (0) = 1
y = cos (360) = 1
Therefore, the period is 360.
Answer:
the period for the graph of y = cos (0) is:
c.360
