Complex.Sin(Complex) 方法

定義

傳回指定複數的正弦函數。

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

參數

value
Complex

複數。

傳回

value的正弦函數。

範例

下列範例說明 Sin 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

Sin複數的 方法會對應至Math.Sin實數的 方法。

方法 Sin 會使用下列公式來計算複數 a + bi 的正弦值:

(Sin () * Cosh (b) , Cos () * Sinh (b) )
