Returns the tangent of an angle.
Synopsis
`Tan(number)`
Arguments
The number argument can be any valid numeric expression that expresses an angle in radians.
Description
Tan takes an angle and returns the ratio of two sides of a right triangle. The ratio is the length of the side opposite the angle divided by the length of the side adjacent to the angle
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 Tan function to return the tangent of an angle:
```Dim MyAngle
MyAngle = 1.3           ' Define angle in radians.
Println Tan(MyAngle)    ' Calculate tangent.
```

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