COTH

COTH is a DAX function that returns the hyperbolic cotangent of a hyperbolic angle.

Syntax

COTH( Number )

Argument	Properties	Description
Number		Any real number.

Return Values

The hyperbolic cotangent of the given angle.

Remarks

• The hyperbolic cotangent is an analog of the ordinary (circular) cotangent.

• The absolute value of number must be less than $2^{27}$ and cannot be 0.

• If number is outside its constraints, an error is returned

• If number is a non-numeric value, an error is returned.

• The following equation is used:

  $$\text{COTH}(N)=\frac{1}{\text{TANH}(N)}=\frac{\text{COSH(N)}}{\text{SINH(N)}}=\frac{e^N+e^{-N}}{e^N-e^{-N}}$$

• This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.

The following DAX query,

EVALUATE { COTH(2) }

Returns

[Value]
1.03731472072755
