Complex.Asin(Complex) 方法

定義

命名空間:

System.Numerics

組件:

System.Runtime.Numerics.dll

來源:

Complex.cs

傳回角度，這個角度是指定之複數的反正弦值。

public:
 static System::Numerics::Complex Asin(System::Numerics::Complex value);

public static System.Numerics.Complex Asin (System.Numerics.Complex value);

static member Asin : System.Numerics.Complex -> System.Numerics.Complex

Public Shared Function Asin (value As Complex) As Complex

參數

value

Complex

複數。

傳回

Complex

反正弦值為 value 的角度。

範例

下列範例說明 Asin 方法。 它會顯示將 方法傳 Asin 回的值傳遞至 Sin 方法會傳回原始 Complex 值。

using System;
using System.Numerics;

public class Example
{
   public static void Main()
   {
      Complex[] values = { new Complex(2.3, 1.4),
                           new Complex(-2.3, 1.4),
                           new Complex(-2.3, -1.4),
                           new Complex(2.3, -1.4) };
      foreach (Complex value in values)
         Console.WriteLine("Sin(Asin({0})) = {1}",
                            value, Complex.Sin(Complex.Asin(value)));
   }
}
// The example displays the following output:
//       Sin(Asin((2.3, 1.4))) = (2.3, 1.4)
//       Sin(Asin((-2.3, 1.4))) = (-2.3, 1.4)
//       Sin(Asin((-2.3, -1.4))) = (-2.3, -1.4)
//       Sin(Asin((2.3, -1.4))) = (2.3, -1.4)

Imports System.Numerics

Module Example
   Public Sub Main()
      Dim values() As Complex = { New Complex(2.3, 1.4),
                                  New Complex(-2.3, 1.4), 
                                  New Complex(-2.3, -1.4),
                                  New Complex(2.3, -1.4) }
      For Each value As Complex In values
         Console.WriteLine("Sin(Asin({0})) = {1}", 
                            value, Complex.Sin(Complex.Asin(value)))
      Next                      
   End Sub
End Module
' The example displays the following output:
'       Sin(Asin((2.3, 1.4))) = (2.3, 1.4)
'       Sin(Asin((-2.3, 1.4))) = (-2.3, 1.4)
'       Sin(Asin((-2.3, -1.4))) = (-2.3, -1.4)
'       Sin(Asin((2.3, -1.4))) = (2.3, -1.4)

備註

Asin複數的方法會對應至 Math.Asin 實數的 方法。

方法 Asin 會使用下列公式：

-ImaginaryOne * Log (ImaginaryOne * value + Sqrt (One - value * value) )
