.Tanh()

The Math.Tanh() method returns the hyperbolic tangent of a given angle in radians.

Syntax

Math.Tahn(x);

This method accepts a single parameter,x, which is the angle in radians. It returns the hyperbolic tangent value of x.

Example

The example below declares two double values, x and y, and then calculates the hyperbolic tangent of x using the Math.Tanh() function. The resulting value is stored in y. Finally, the value of y is printed to the console.

using System;

public class Program
{
  public static void Main()
  {
    double x = 2;
    double y = Math.Tanh(x);

    Console.WriteLine(y);
    // Output: 0.9640275800758169
  }
}
