# Hyperbolic Secant Calculator or sech(x)

Written by:

On this page is a hyperbolic secant calculator, which works for an input of a hyperbolic angle. Enter the hyperbolic angle and choose the units and run the calculator to see the hyperbolic secant.

## Using the Hyperbolic Secant Calculator

To use the tool to find the hyperbolic secant, enter the measurement of a hyperbolic angle and run the tool.

• Angle - measurement of the angle

Once you're happy with the inputs, click the "Compute Hyperbolic Secant" button.

• Hyperbolic Secant - the result of the calculation

## What is the hyperbolic secant?

Hyperbolic secant is the reciprocal of the of the hyperbolic cosine or:

sech(x)=\frac{1}{\cosh(x)}=\frac{2}{e^{x}+e^{-x}}

### Hyperbolic secant as a formula

As a hyperbolic function, hyperbolic secant is usually abbreviated as "sech", as in the following equation:

sech(\theta)

If you already know the hyperbolic secant, use the inverse hyperbolic secant or arcsech to find the angle.

After, see the hyperbolic functions and inverse hyperbolic functions in two convenient tools.
