## 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.*
