# C++ Math cosh()

The function finds the hyperbolic cosine of an angle given in radian.

Mathematically,

coshx = ex+ e-x/2

## Syntax

Suppose the hyperbolic angle is 'x':

## Parameter

x: The value of angle whose hyperbolic cosine is to be calculated.

## Return value

It returns the hyperbolic cosine of angle given in radian.

## Example 1

Let's see a simple example when the value of x is of integral type.

Output:

```Value of degree is :45
```

In this example, cosh() computes the hyperbolic cosine of an angle 45 and returns the value 1.324.

## Example 2

Let's see another simple example.

Output:

```Value of degree is: 25.5
```
