# `Cosh`

``Cosh( value )``
``Cosh( value )``
``Cosh( value )``
``Cosh( value )``
``cosh( value )``
``Cosh( value )``

## Description

The `Cosh` function is a trigonometric function which calculates ratios of the lengths of the sides of right triangles. `Cosh` returns the hyperbolic cosine of a number.

## Parameters

Parameter Type Definition and Requirements

`value`

The Number whose hyperbolic cosine should be returned.

## Returns

A Number which is the hyperbolic cosine of `value`.

## Examples

The following query calculates the hyperbolic cosine of 0.5.

``````try
{
Value result = await client.Query(
Cosh(0.5)
);

Console.WriteLine(result);
}
catch (Exception e)
{
Console.WriteLine(\$"ERROR: {e.Message}");
}``````
``DoubleV(1.1276259652063807)``
``````result, err := client.Query(
f.Cosh(0.5))

if err != nil {
fmt.Fprintln(os.Stderr, err)
} else {
fmt.Println(result)
}``````
``1.1276259652063807``
``````System.out.println(
client.query(
Cosh(Value(0.5))
).get());``````
``1.1276259652063807``
``````client.query(
q.Cosh(0.5)
)
.then((ret) => console.log(ret))
.catch((err) => console.error(
'Error: [%s] %s: %s',
err.name,
err.message,
err.errors().description,
))``````
``1.1276259652063807``
``````result = client.query(
q.cosh(0.5)
)
print(result)``````
