Cosine 180 Degree Functions | Cos 180 Degree

Cos 180 Degree. The cosine function, denoted as cos(θ), is one of the six fundamental trigonometric functions used to relate the angles of a right triangle to the ratios of its sides.

In a right-angled triangle, the cosine of an angle is defined as the ratio of the length of the adjacent side to the length of the hypotenuse. The cosine function is periodic, oscillating between values of -1 and 1 as the angle varies. It is an essential concept in trigonometry, used extensively in mathematics, physics, engineering, and various other fields.


Understanding Cosine of 180 Degrees

When we talk about cos 180, we’re referring to evaluating the cosine function at an angle of 180 degrees. The value of cos(180°) is -1. This means that in a right triangle with a 180-degree angle, the adjacent side’s length is negative relative to the hypotenuse.
