The COTH function returns the hyperbolic cotangent of a hyperbolic angle.
- This function was introduced in Excel 2013 and so is not available in earlier versions.
|number||The angle, in radians, that you want to calculate the hyperbolic cotangent of
|2||=COTH(2)||1.037||Returns the hyperbolic cotangent of 2|
|3||=COTH(RADIANS(120))||1.030796253||Returns the hyperbolic cotangent of 120 degrees|
|4||=COTH(PI()/2)||1.090331411||The PI function is used to provide the value π/2 to the COTH function|
Note: If the angle is in degrees, you need to be convert it to radians before supplying it to the COTH function. You can convert it, using the RADIANS function: =RADIANS(degrees)
Common Function Error(s)

The hyperbolic cotangent is the reciprocal of the hyperbolic tangent and is calculated as:
