The cosine function, denoted as cos(x), is a trigonometric function that represents the ratio of the adjacent side to the hypotenuse in a right triangle. In simpler terms, it gives the value of the cosine of an angle x in a right-angled triangle. The cosine function has a range of -1 to 1, and its value varies depending on the angle x. It is an important function in trigonometry and is used in various mathematical and scientific applications.
