Función COS(number)
Calculates the cosine of the argument “number”.
Returns a numeric value greater than or equal to -1 and less than or equal to 1.
Accepts exactly one argument of the type number, which represents an angle
expressed in radians. The cosine is a continuos function, therefore, the
argument can take any numeric positive, negative o zero. For expample:
=COS(0) Returns 1.
=COS(2*PI()) Returns 0.
=COS(PI()) Returns -1.
