MathF.Cosh() Method in C# with Examples
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
