Microsoft® Visual Basic® Scripting Edition Tan Function | Language Reference Version 1

See Also

##### Description

> Returns the tangent of an angle.

##### Syntax

> Tan(number)

> The number 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 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.

> The following example uses the Tan function to return the tangent of an angle:

> >     Dim MyAngle, MyCotangent
> >     MyAngle = 1.3                     ' Define angle in radians.
> >     MyCotangent = 1 / Tan(MyAngle)    ' Calculate cotangent.
