Description
Cos returns a Number specifying the cosine of an angle given in radians.
Arguments
Number value which is an angle in number of radians.
Returns
Number value between –1 and 1
Action
Cos returns a Number specifying the cosine of an angle given in radians. It takes a right-angle triangle, and returns the length of the side adjacent to the specified angle divided by the length of the hypotenuse.
Examples
Cos (1)
Returns 0.5403 (rounded to 4 decimals). This is the cosine of 1 radian.
Cos (60 * crPi / 180)
Returns 0.5. This is the cosine of 60 degrees. Before taking the cosine, the angle is converted to radians by multiplying by crPi / 180.
Comments
The range of values returned by Cos is between -1 and 1.
