Complex.Asin(Complex) Metode

Definisi

Mengembalikan sudut yang merupakan sinus busur dari bilangan kompleks yang ditentukan.

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

Parameter

value
Complex

Bilangan kompleks.

Mengembalikan

Sudut yang merupakan sinus busur value.

Contoh

Contoh berikut mengilustrasikan metode Asin. 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)

                                  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)))

Keterangan

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

Metode Asin menggunakan rumus berikut:

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