Description
Returns the tangent of an angle.
Syntax
Tan(number)
The number named argument can be any valid numeric expression that expresses an angle in radians.
Remarks
Tan takes an angle and returns the ratio of two sides of a right triangle. The ratio is the length of the side opposite an 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.

Example
This example uses the Tan function to return the tangent of an angle.
MyAngle = 1.3 ' Define angle in radians. MyCotangent = 1 / Tan(MyAngle) ' Calculate cotangent.
