Purpose
Get the hyperbolic cotangent of an angle
Return value
The hyperbolic cotangent
Syntax
=COTH(number)- number - The hyperbolic angle.
Using the COTH function
The Excel COTH function returns the hyperbolic cotangent of a hyperbolic angle. Given 1.00 as input, the function returns 1.313035285 as output.
=COTH(1) // returns 1.313035285
Explanation
The hyperbolic cotangent is the reciprocal of the TANH function.
=1/TANH(x) // equivalent to COTH(x)
The plot below shows the COTH function’s output in Excel.
Notes:
- Returns a #DIV/0! error when given zero as input.
