Math.Cosh(Single) Method is the inbuilt MathF class method which returns the hyperbolic cosine of a given single value argument. 
 

Syntax: public static float Cosh (float x); 
Here, x is the number whose hyperbolic cosine is to be returned and type of this parameter is System.Single
 

Return Value: This method returns the hyperbolic cosine of x of type System.Single. If x is equal to NegativeInfinity or PositiveInfinity, PositiveInfinity is returned. If x is equal to NaN, NaN is returned.
Below programs illustrate the use of the above-discussed method:
Example 1:
 

Csharp




// C# program to illustrate the
// MathF.Cosh(Single) Method
using System;
 
class GFG {
 
    // Main Method
    public static void Main(String[] args)
    {
 
        float num1 = 60.0f, num2 = 0.0f, num3 = 1.0f;
 
        // It returns the hyperbolic cosine
        // of specified angle in radian
        float coshvalue = MathF.Cosh(num1);
        Console.WriteLine("The Cosh of num1 = " + coshvalue);
 
        coshvalue = MathF.Cosh(num2);
        Console.WriteLine("The Cosh of num2 = " + coshvalue);
 
        coshvalue = MathF.Cosh(num3);
        Console.WriteLine("The Cosh of num3 = " + coshvalue);
    }
}
Output: 
The Cosh of num1 = 5.710037E+25
The Cosh of num2 = 1
The Cosh of num3 = 1.543081

 

Example 2:
 

Csharp




// C# program to illustrate the
// MathF.Cosh(Single) Method
using System;
 
class GFG {
 
    // Main Method
    public static void Main()
    {
         
        float num1 = (30 * (MathF.PI)) / 180;
         
        // calling result() method
        result(num1);
        result(Single.NaN);
        result(Single.NegativeInfinity);
        result(Single.PositiveInfinity);
    }
 
    // defining result() method
    public static void result(float value)
    {
 
        // using the method
        float result = MathF.Cosh(value);
 
        // Display the value
        Console.WriteLine("Cosh({0}) will be {1}",
                                value, result);
    }
}
Output: 
Cosh(0.5235988) will be 1.140238
Cosh(NaN) will be NaN
Cosh(-Infinity) will be Infinity
Cosh(Infinity) will be Infinity
