TANH DAX Function (Math and Trig)
Returns the hyperbolic tangent of a number.
Syntax
Parameter | Attributes | Description |
---|---|---|
Number |
Any real number. |
Return values
Returns the hyperbolic tangent of a number.
Remarks
The formula for the hyperbolic tangent is:
TANH ( z ) = SINH ( z ) / COSH ( z )
Examples
-- SINH, COSH, ASINH, ACOSH, TANH, ATANH, COTH, ACOTH -- are the standard hyperbolic trigonometrical functions. -- -- Where required, the arguments are specified in radians.
