Cosinus function
WebThe cosine function is a periodic function which is very important in trigonometry. The simplest way to understand the cosine function is to use the unit circle. For a given angle measure , draw a unit circle on the coordinate plane and draw the angle centered at the origin, with one side as the positive -axis. WebSep 13, 2024 · The Cos function takes an angle and returns the ratio of two sides of a right triangle. The ratio is the length of the side adjacent to the angle divided by the length of the hypotenuse.The result lies in the range -1 to 1. To convert degrees to radians, multiply degrees by pi /180. To convert radians to degrees, multiply radians by 180/pi.

Some of them are listed below: The cos x graph repeats itself after 2π, which suggests the function is periodic with a period of 2π. Cos x is an even function because cos (−x) = cos x. The domain of cosine function is all real numbers and the range is [-1,1].
