Version: 1 | Requires: ColdFusion 5 | Library: MathLib

Rated 0 time(s). Average Rating: 0

Description:
Returns the hyperbolic cosecant of an angle. If angle is 0, returns "undefined". All angles are expressed in radians.

Return Values:
Returns a numeric value or string.

Example:

view plain print about

<CFSET x=(Pi()/2)>
<CFOUTPUT>
Given x=#x#<BR>
The Csch of #x# radians is: #Csch(x)#
</CFOUTPUT>

<CFSET x=(Pi()/2)>
<CFOUTPUT>
Given x=#x#<BR>
The Csch of #x# radians is: #Csch(x)#
</CFOUTPUT>

Parameters:

Name	Description	Required
x	Any angle expressed in radians.	Yes
