Returns the cosine of an angle.
Synopsis
`Cos(number)`
Arguments
The number argument can be any valid numeric expression that expresses an angle in radians.
Description
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.
Examples
The following example uses the Cos function to return the cosine of an angle:
```Dim MyAngle
MyAngle = 1.3           ' Define angle in radians.
Println Cos(MyAngle)    ' Calculate cosine.```

The following example uses the Cos function to return the secant of an angle:
```Dim MyAngle, MySecant
MyAngle = 1.3                ' Define angle in radians.
MySecant = 1 / Cos(MyAngle)  ' Calculate secant.
Println MySecant```
