Complex.Sin(Complex) 方法

定義

命名空間:

System.Numerics

組件:

netstandard.dll, System.Runtime.Numerics.dll

來源:

Complex.cs

返回指定複數的正弦值。

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

Complex

的 value正弦。

範例

以下範例說明此 Sin 方法。 它顯示將方法回傳 Asin 的值傳給方法 Sin 時，會返回原始 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)

open System.Numerics

let values =
    [ Complex(2.3, 1.4)
      Complex(-2.3, 1.4)
      Complex(-2.3, -1.4)
      Complex(2.3, -1.4) ]

for value in values do
    printfn $"Sin(Asin({value})) = {Complex.Asin value |> Complex.Sin}"
// 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)

                                  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複數的方法對應Math.Sin於實數的方法。

該 Sin 方法計算複數 a + bi 的正弦為 x + yi，其中：

• x 是 \ 在 \ 時間 \ c的 b$ 中
• y 是$\因為是\sinh b$
