Returns the tangent of the specified double that represents an angle.
[Edit]
Parameters
- a
- A double that represents an angle measured in radians.
[Edit]
Returns
A double containing the value of the tangent of a. If a
is equal to double.NaN, double.NegativeInfinity, or double.PositiveInfinity,
returns double.NaN.

Remarks
Example
The following example demonstrates using the Math.Tan(double) method.
| C# Example |
using System;
public class MathTanExample
{
public static void Main()
{
Double d1 = Math.Tan(0);
Double d2 = Math.Tan(Math.PI/2.0);
Console.WriteLine("Math.Tan(0) returns {0}", d1);
Console.WriteLine("Math.Tan(Math.PI/2.0) returns {0}", d2);
}
}
|
The output is
Math.Tan(0) returns 0
Math.Tan(Math.PI/2.0) returns 1.63317787283838E+16
