Exemplos

O exemplo a seguir ilustra o Tan método.The following example illustrates the Tan method. Ele mostra que a passagem do valor retornado pelo Atan método para o Tan método retorna o Complex valor original.It shows that passing the value returned by the Atan method to the Tan method returns the original Complex value.

using System;
using System.Numerics;

public class Example
{
   public static void Main()
   {
      Complex[] values = { new Complex(2.5, 1.5),
                           new Complex(2.5, -1.5),
                           new Complex(-2.5, 1.5),
                           new Complex(-2.5, -1.5) };
      foreach (Complex value in values)
         Console.WriteLine("Tan(Atan({0})) = {1}",
                            value, Complex.Tan(Complex.Atan(value)));
   }
}
// The example displays the following output:
//       Tan(Atan((2.5, 1.5))) = (2.5, 1.5)
//       Tan(Atan((2.5, -1.5))) = (2.5, -1.5)
//       Tan(Atan((-2.5, 1.5))) = (-2.5, 1.5)
//       Tan(Atan((-2.5, -1.5))) = (-2.5, -1.5)

                                  New Complex(-2.5, -1.5) }
      For Each value As Complex In values
         Console.WriteLine("Tan(Atan({0})) = {1}",

Comentários

O Tan método para números complexos corresponde ao Math.Tan método para números reais.The Tan method for complex numbers corresponds to the Math.Tan method for real numbers.

O Tan método usa a fórmula a seguir para calcular a tangente do número complexo value :The Tan method uses the following formula to calculate the tangent of the complex number value:

Sin(value) / Cos(value)Sin(value) / Cos(value)
