SECH

SECH(number)

Returns the hyperbolic secant of a number.

number

The number you want the hyperbolic secant of.

REMARKS

* For an illustrated example refer to the Hyperbolic Functions page.
* The hyperbolic secant of a number is 1/COSH.
* This function does not have an inverse function.
* If Abs(number) > 2^27, then #NUM is returned.
* If "number" is not numeric, then #VALUE is returned.
* You can use the SINH function to return the hyperbolic sine.
* You can use the COTH function to return the hyperbolic cotangent.
* You can use the CSCH function to return the hyperbolic cosecant.
* This function was added in Excel 2013.
