The Excel Sech function calculates the hyperbolic secant (sech) of a supplied angle.
Note: the Sech function was only introduced in Excel 2013 and so is not available in earlier versions of Excel.
The syntax of the function is:
Where the number argument is the angle (in radians) that you want to calculate the hyperbolic secant of. This must be between -2^27 and +2^27.
Converting from Degrees to RadiansAn example of this is provided below.
In the following spreadsheet, the Excel Sech Function is used to calculate the hyperbolic secant of four different angles:
Note that, in the examples above:
For further details and examples of the Excel Sech function, see the Microsoft Office website.
If you get an error from the Excel Sech function, this is likely to be one of the following:
|#NUM!||-||Occurs if the supplied number is less than -2^27 or is greater than 2^27.|
|#VALUE!||-||Occurs if the supplied number argument is not recognized as a numeric value.|
