# Complex.Tan(Complex) Metoda

## Definicja

Zwraca tangens podanej liczby zespolonej.Returns the tangent of the specified complex number.

``````public:
static System::Numerics::Complex Tan(System::Numerics::Complex value);``````
``public static System.Numerics.Complex Tan (System.Numerics.Complex value);``
``static member Tan : System.Numerics.Complex -> System.Numerics.Complex``
``Public Shared Function Tan (value As Complex) As Complex``

#### Parametry

value
Complex

Liczba złożona.A complex number.

#### Zwraca

Tangens `value`.The tangent of `value`.

Poniższy przykład ilustruje Tan metodę.The following example illustrates the Tan method. Pokazuje, że przekazywanie wartości zwracanej przez Atan metodę Tan do metody zwraca oryginalną Complex wartość.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)

## Uwagi

Metoda dla liczb zespolonych odpowiada Math.Tan metodzie liczb rzeczywistych. TanThe Tan method for complex numbers corresponds to the Math.Tan method for real numbers.

Metoda używa następującej formuły, aby obliczyć tangens liczby `value`zespolonej: TanThe Tan method uses the following formula to calculate the tangent of the complex number `value`:

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