VBScript Tan Function

Returns the tangent of an angle.

Syntax: VBScript Tan Function

Tan(number)

Arguments: VBScript Tan Function

number

Any valid numeric expression that expresses an angle in radians.

Remarks: VBScript Tan Function

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.
