Complex.Sin(Complex) Metoda

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

Sinus value.

Poniższy przykład ilustruje metodę Sin. Pokazuje, że przekazanie wartości zwróconej przez metodę Asin do metody Sin zwraca oryginalną wartość Complex.

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)

for value in values do

Metoda Sin liczb zespolonych odpowiada metodzie Math.Sin dla liczb rzeczywistych.

Metoda Sin oblicza sinus liczby zespolonej a + bi jako x + yi, gdzie:

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

• Asin(Double)
• Sin(Complex)
