Parameter Type Definition and Requirements

value

Number

The Number whose tangent should be returned.

Returns

A Number which is the tangent of value.

Examples

The following query returns the tangent of 0.5:

client.query(
  q.Tan(0.5)
)
.then((ret) => console.log(ret))
.catch((err) => console.error(
  'Error: [%s] %s: %s',
  err.name,
  err.message,
  err.errors()[0].description,
))
0.5463024898437905
result = client.query(
  q.tan(0.5)
)
print(result)
0.5463024898437905
result, err := client.Query(
	f.Tan(0.5))

if err != nil {
	fmt.Fprintln(os.Stderr, err)
} else {
	fmt.Println(result)
}
0.5463024898437905
try
{
    Value result = await client.Query(
        Tan(0.5)
    );

    Console.WriteLine(result);
}
catch (Exception e)
{
    Console.WriteLine($"ERROR: {e.Message}");
