# Hyperbolic Cosine Calculator or cosh(x)

Written by:
PK

On this page is a hyperbolic cosine 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 cosine.

## Using the Hyperbolic Cosine Calculator

To use the tool to find the hyperbolic cosine, enter the measurement of a hyperbolic angle and compute.

• Angle - measurement of the angle

Once you're happy with the input, click the "Compute Hyperbolic Cosine" button.

• Hyperbolic Cosine - the result of the calculation

## What is the hyperbolic cosine?

Hyperbolic cosine is the even part of the exponential function (where hyperbolic sine is the odd):

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

### Hyperbolic cosine as a formula

As a hyperbolic function, hyperbolic cosine is usually abbreviated as "cosh", as in the following equation:

\cosh(\theta)

If you already know the hyperbolic cosine, use the inverse hyperbolic cosine or arccosh to find the angle.

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