Math and Trignometric - COTH Function
Description
The COTH function returns the hyperbolic cotangent of a hyperbolic angle.
Syntax
COTH (number)
Arguments
Argument | Description | Required/Optional |
---|---|---|
Number | The angle in radians for which you want the hyperbolic cotangent. | Required |
Notes
The following equation is used −
$$\coth \left ( N \right ) = \frac{1}{\tanh \left ( N \right )} = \frac{\cosh\left ( N \right ) }{\sinh \left ( N \right )} = \frac{e^N+e^{-N}}{e^N-e^{-N}}$$
If the angle is in degrees, convert it to radians by multiplying with by PI()/180 or use the RADIANS Function
=RADIANS (degrees)
The absolute value of Number must be less than 2^27.
If Number is outside its constraints, COTH returns the #NUM! error value.
If Number is a non-numeric value, COTH returns the #VALUE! error value.
COTH (0) returns the #DIV/0! error value.
Applicability
Excel 2013, Excel 2016
