# Complex.Sin(Complex) Méthode

## Définition

Retourne le sinus du nombre complexe spécifié.Returns the sine of the specified complex number.

``````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``

#### Paramètres

value
Complex

Nombre complexe.A complex number.

#### Retours

Sinus de `value`.The sine of `value`.

## Exemples

L’exemple suivant illustre la méthode Sin.The following example illustrates the Sin method. Elle indique que le passage de la valeur retournée par la méthode Asin à la méthode Sin retourne la valeur de Complex d’origine.It shows that passing the value returned by the Asin method to the Sin method returns the original Complex value.

``````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

' 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)

## Remarques

La méthode Sin pour les nombres complexes correspond à la méthode Math.Sin pour les nombres réels.The Sin method for complex numbers corresponds to the Math.Sin method for real numbers.

La méthode Sin utilise la formule suivante pour calculer le sinus du nombre complexe a + bi :The Sin method uses the following formula to calculate the sine of the complex number a + bi:

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