Cosine, written as cos⁡ (θ), is one of the six fundamental trigonometric functions. There are two main ways in which trigonometric functions are typically discussed: in terms of right triangles …

Illustrated definition of Cosine: In a right angled triangle, the cosine of an angle is: The length of the adjacent sidedivided by the length...

The cosine can be defined as the ratio of the length of the base to the length of the hypotenuse in a right-angled triangle. It gives the value of the cosine function for angle x, denoted by cos x.

The cosine function (or cos function) in a triangle is the ratio of the adjacent side to that of the hypotenuse. The cosine function is one of the three main primary trigonometric functions and it …
