The Excel SECH function returns the hyperbolic secant of an angle.

Purpose 

Get hyperbolic secant of an angle

Return value 

The hyperbolic secant of the angle

Syntax

=SECH(number)
  • number - The hyperbolic angle.

How to use 

The Excel SECH function returns the hyperbolic secant of a hyperbolic angle angle. Given 2 as input, the function returns 0.265802229 as output.

=SECH(2) // returns 0.265802229
