The SECH function returns the hyperbolic secant of an angle.
- This function was introduced in Excel 2013 and so is not available in earlier versions.
|number||The number argument is the angle, in radians, for which you want the hyperbolic secant
|2||=SECH(0.785398)||0.75494||The hyperbolic secant of a 45 degree angle|
|3||=SECH(RADIANS(45))||0.75494||The hyperbolic secant of a 45 degree angle|
|4||=SECH(PI()/4)||0.75494||The hyperbolic secant of a 45 degree angle|
Note: If the angle is in degrees, you need to be convert it to radians before supplying it to the SECH function. You can convert it, using the RADIANS function: =RADIANS(degrees)

The hyperbolic secant is the reciprocal of the hyperbolic cosine. The value for hyperbolic secant is given by the following equation:
