COSH

COSH is a DAX function that returns the hyperbolic cosine of a number.

Syntax

COSH( Number )

Argument	Properties	Description
Number		Any real number for which you want to find the hyperbolic cosine.

Return Values

The hyperbolic cosine of a number.

Remarks

• The formula for the hyperbolic cosine is:

  $$\text{COSH}(z)=\frac{e^z+e^{-z}}{2}$$

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