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

Number

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.

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()[0].description,
))

result = client.query(
  q.cosh(0.5)
)
print(result)
1.1276259652063807
result, err := client.Query(
	f.Cosh(0.5))

if err != nil {
	fmt.Fprintln(os.Stderr, err)
} else {
	fmt.Println(result)
}

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

    Console.WriteLine(result);
}
