Complex.Sin(Complex) Metode

Definisi

Ruang nama:

System.Numerics

Rakitan:

System.Runtime.Numerics.dll

Sumber:

Complex.cs

Mengembalikan sinus dari bilangan kompleks yang ditentukan.

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

Parameter

value

Complex

Bilangan kompleks.

Mengembalikan

Complex

Sinus value.

Contoh

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

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)

Keterangan

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

Metode Sin menghitung sinus bilangan kompleks a + bi sebagai x + yi, di mana:

• x adalah $\sin a \times \cosh b$
• y adalah $\cos a \times \sinh b$
