C# Math.Cosh() – Examples
In this tutorial, we will learn about the C# Math.Cosh() method, and learn how to use this method to find the hyperbolic cosine of given angle, with the help of examples.
Cosh(Double)
Math.Cosh(value) returns the hyperbolic cosine of the specified angle value

Syntax
The syntax of Cosh() method is
Math.Cosh(Double value)
where
Parameter | Description |
---|---|
value | The value represents radians for which hyperbolic cosine is to be calculated. |
Return Value
The method returns value of type Double.
Example 1 – Cosh(Double)
In this example, we will find the hyperbolic cosine of some angles like 1 radian, PI radians, PI/2 radians, 0 radians, Infinity radians, -Infinity radians.
C# Program
using System; class Example { static void Main(string[] args) { Double value, result; value = 1; //1 radian result = Math.Cosh(value); Console.WriteLine($"Cosh({value} radian) = {result}."); value = Math.PI; // PI radians or 180 degrees result = Math.Cosh(value); Console.WriteLine($"Cosh({value} radian) = {result}."); value = Math.PI/2; // 90 degrees result = Math.Cosh(value); Console.WriteLine($"Cosh({value} radian) = {result}."); value = 0; // 0 degrees result = Math.Cosh(value); Console.WriteLine($"Cosh({value} radian) = {result}."); value = Double.PositiveInfinity; result = Math.Cosh(value); Console.WriteLine($"Cosh({value} radian) = {result}."); value = Double.NegativeInfinity; result = Math.Cosh(value); Console.WriteLine($"Cosh({value} radian) = {result}."); } }
Output
Cosh(1 radian) = 1.54308063481524. Cosh(3.14159265358979 radian) = 11.5919532755215. Cosh(1.5707963267949 radian) = 2.50917847865806. Cosh(0 radian) = 1. Cosh(∞ radian) = ∞. Cosh(-∞ radian) = ∞.
Conclusion
In this C# Tutorial, we have learnt the syntax of C# Math.Cosh() method, and also learnt how to use this method with the help of C# example programs.
