Description

The Acos function is a trigonometric function which calculates ratios of the lengths of the sides of right triangles. Acos returns the arc cosine of a number.

Parameters

Parameter Type Definition and Requirements

value

Number

The Number whose arc cosine should be returned.

Returns

A Number which is the arc cosine of value.

Examples

The following query returns the arc cosine of 0.5:

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

    Console.WriteLine(result);
}
catch (Exception e)
{
    Console.WriteLine($"ERROR: {e.Message}");
}
DoubleV(1.0471975511965979)
result, err := client.Query(
	f.Acos(0.5))

if err != nil {
	fmt.Fprintln(os.Stderr, err)
} else {
	fmt.Println(result)
}
1.0471975511965979
System.out.println(
    client.query(
        Acos(Value(0.5))
    ).get());
1.0471975511965979
client.query(
  q.Acos(0.5)
)
.then((ret) => console.log(ret))
.catch((err) => console.error(
  'Error: [%s] %s: %s',
  err.name,
  err.message,
  err.errors()[0].description,
))
1.0471975511965979
result = client.query(
  q.acos(0.5)
)
print(result)
1.0471975511965979
Acos(0.5)
