Cos Function

Returns the cosine of a numeric expression.

Syntax
Cos (number)

Parameters

number

Specify the angle as a number (radian).

Return Values
Numeric value in radians representing the cosine of the numeric expression number.

Description
Cos returns the cosine of the numeric expression. The numeric expression (number) must be in radian units. The value returned by the Cos function will range from -1 to 1

To convert from degrees to radians, use the DegToRad function.
