Cosine, scale in radians
Description
The cosine of an angle corresponds to the ratio of the adjacent side to the hypotenuse
\(\displaystyle cos(α) = \frac{Adjacent}{Hypotenuse } = \frac{b}{c}\)
Input
The angle is given in degrees (full circle = 360°) or radians (full circle = 2 π). The unit of measurement used is set using the Degrees or Radians menu
Result
Cos gives a result in the range from -1 to 1.
