Mengembalikan sudut yang merupakan tangen busur dari bilangan kompleks yang ditentukan.

public:
 static System::Numerics::Complex Atan(System::Numerics::Complex value);
public static System.Numerics.Complex Atan (System.Numerics.Complex value);
static member Atan : System.Numerics.Complex -> System.Numerics.Complex
Public Shared Function Atan (value As Complex) As Complex

Parameter

value
Complex

Bilangan kompleks.

Mengembalikan

Complex

Sudut yang merupakan tangen busur value.

Contoh

Contoh berikut mengilustrasikan metode Atan. Ini menunjukkan bahwa meneruskan nilai yang dikembalikan oleh metode Atan ke metode Tan mengembalikan nilai Complex asli.

using System;
using System.Numerics;

public class Example
{
   public static void Main()
   {
      Complex[] values = { new Complex(2.5, 1.5),
                           new Complex(2.5, -1.5),
                           new Complex(-2.5, 1.5),
                           new Complex(-2.5, -1.5) };
      foreach (Complex value in values)
         Console.WriteLine("Tan(Atan({0})) = {1}",
                            value, Complex.Tan(Complex.Atan(value)));
   }
}
// The example displays the following output:
//       Tan(Atan((2.5, 1.5))) = (2.5, 1.5)
//       Tan(Atan((2.5, -1.5))) = (2.5, -1.5)
//       Tan(Atan((-2.5, 1.5))) = (-2.5, 1.5)
//       Tan(Atan((-2.5, -1.5))) = (-2.5, -1.5)

open System.Numerics

let values =
    [ Complex(2.5, 1.5)
      Complex(2.5, -1.5)
      Complex(-2.5, 1.5)
      Complex(-2.5, -1.5) ]

for value in values do
    printfn $"Tan(Atan({value})) = {Complex.Atan value |> Complex.Tan}"
// The example displays the following output:
//       Tan(Atan((2.5, 1.5))) = (2.5, 1.5)
//       Tan(Atan((2.5, -1.5))) = (2.5, -1.5)
//       Tan(Atan((-2.5, 1.5))) = (-2.5, 1.5)
//       Tan(Atan((-2.5, -1.5))) = (-2.5, -1.5)

                            value, Complex.Tan(Complex.Atan(value)))

' The example displays the following example:
'       Tan(Atan((2.5, 1.5))) = (2.5, 1.5)
'       Tan(Atan((2.5, -1.5))) = (2.5, -1.5)

'       Tan(Atan((-2.5, -1.5))) = (-2.5, -1.5)

Keterangan

Metode Atan untuk bilangan kompleks sesuai dengan metode Math.Atan untuk bilangan riil.

Metode Atan menggunakan rumus berikut:

(ImaginaryOne / new Complex(2.0, 0.0)) * (Log(One - ImaginaryOne * value) - Log(One + ImaginaryOne * value))
