Purpose
Return value
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
Explanation
The hyperbolic secant is the reciprocal of the COSH function.
=1/COSH(x) // equivalent to SECH(x)
