The SECH function returns the hyperbolic secant of an angle.
Formula:
=SECH(number)
Explanations:
Number is required, the angle in radians you want the hyperbolic secant.
Cautions:
- The number is the angle in radians. If the angle is in degrees, use PI()/180 or the RADIANS function to covert the angle to radians.
- SECH function applies to Excel 2016, Excel 2013, Excel 2016 for Mac, Excel 2011 for Mac.
