SOLUTION: How do I figure out the values of X when I'm given cosine of x = 1? I've looked at the unit circle and the different radians, and I know that the answer is supposed to be in radian

Question 799570: How do I figure out the values of X when I'm given cosine of x = 1? I've looked at the unit circle and the different radians, and I know that the answer is supposed to be in radians. I also know that cosine is x/ radius for a regular circle, and x/ 1 for a unit circle. The problem is I don't know how to get started.

How do I figure out the values of X when I'm given cosine of x = 1?
-----
On a unit circle, the cosine is "x" for each point (x,y) on the circle.

When does x = 1 ???
Answer: 0 radians
