How to Find the Value of Cos 180 Degrees? The value of cos 180 degrees can be calculated by constructing an angle of 180° with the x-axis, and then finding the coordinates of the corresponding point (-1, 0) on the unit circle. The value of cos 180° is equal to the x-coordinate (-1). ∴ cos 180° = -1. What is the Exact Value of cos 180 Degrees?
