Math and Trignometric - COTH Function

Description

The COTH function returns the hyperbolic cotangent of a hyperbolic angle.

Syntax

COTH (number)

Arguments

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
