COS

 

Syntax: @COS(X)

X = a numeric value expressed in radians.

@COS returns the cosine of angle X. The result is between -1 and 1. (To convert the argument from degrees to radians, use the @RADIANS function.)

Examples:

@COS(-45) = 0.52532199

@COS(K24) = 0.5403023, where K24 = 1

@COS(@RADIANS(30)) = 0.866025
