Cos Function
Returns a Double specifying the cosine of an angle.
Syntax
Cos(number)
The required number argument is a Double or any valid numeric expression that expresses an angle in radians.
Remarks
The Cos function takes an angle and returns the ratio of two sides of a right triangle. The ratio is the length of the side adjacent to the angle divided by the length of the hypotenuse.
The result lies in the range -1 to 1.
To convert degrees to radians, multiply degrees by pi/180. To convert radians to degrees, multiply radians by 180/pi.
Example
This example uses the Cos function to return the cosine of an angle.
