Complex.Tan(Complex) Complex.Tan(Complex) Complex.Tan(Complex) Complex.Tan(Complex) Method

定義

指定した複素数のタンジェントを返します。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

パラメーター

value
Complex Complex Complex Complex

複素数。A complex number.

戻り値

value のタンジェント。The tangent of value.

次の例は、 Tanメソッドを示しています。The following example illustrates the Tan method. メソッドによってAtan返された値をTanメソッドに渡すと、元Complexの値が返されることがわかります。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)

Module Example
   Public Sub Main()
      Dim values() As Complex = { New Complex(2.5, 1.5), 
                                  New Complex(2.5, -1.5), 
                                  New Complex(-2.5, 1.5), 
                                  New Complex(-2.5, -1.5) }
      For Each value As Complex In values
         Console.WriteLine("Tan(Atan({0})) = {1}", 
                            value, Complex.Tan(Complex.Atan(value)))
      Next                               
   End Sub

' The example displays the following example:
'       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)

注釈

複素数Tanのメソッドは、実数のMath.Tanメソッドに対応しています。The Tan method for complex numbers corresponds to the Math.Tan method for real numbers.

メソッドTanは、次の式を使用して、 value複素数のタンジェントを計算します。The Tan method uses the following formula to calculate the tangent of the complex number value:

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