Retourneert de hoek die de boogtangens van het opgegeven complexe getal is.

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

Parameters

value
Complex

Een complex getal.

Retouren

Complex

De hoek die de boogtangens van valueis.

Voorbeelden

In het volgende voorbeeld ziet u de Atan methode. Het laat zien dat het doorgeven van de waarde die door de Atan methode aan de Tan methode wordt geretourneerd, de oorspronkelijke Complex waarde retourneert.

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)

Imports System.Numerics

Module Example
   Public Sub Main()
      Dim values() As Complex = { New Complex(2.5, 1.5), 
                                  New Complex(2.5, -1.5),

                                  New Complex(-2.5, -1.5) }
      For Each value As Complex In values
         Console.WriteLine("Tan(Atan({0})) = {1}", 
                            value, Complex.Tan(Complex.Atan(value)))
      Next                               
   End Sub
End Module
' 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)
'       Tan(Atan((-2.5, -1.5))) = (-2.5, -1.5)

Opmerkingen

De Atan methode voor complexe getallen komt overeen met de Math.Atan methode voor reële getallen.

De Atan methode maakt gebruik van de volgende formule:

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