C# |数学。Cosh()方法

原文:https://www.geeksforgeeks.org/c-sharp-math-cosh-method/

数学。Cosh() 是一个内置的数学类方法，它返回给定双值参数的双曲余弦值。 语法:

public static double Cosh(double num)

参数:

num: 是要返回双曲 cos 的数字，该参数的类型为系统。双。

返回值:该方法返回类型为系统的数值的双曲余弦值。双。如果 num 等于否定有限性或肯定有限性，则返回肯定有限性。如果 num 等于 NaN，则返回 NaN。 例:

Input   : 60.0
Output  : 5.71003694907842E+25

下面的程序说明了数学。Cosh 方法: 程序 1:

c sharp . c sharp . c sharp . c sharp

// C# program to illustrate the
// Math.Cosh()
using System;

class GFG {

    // Main Method
    public static void Main(String[] args)
    {

        double num1 = 60.0, num2 = 0.0, num3 = 1.0;

        // It returns the hyperbolic cosine of
        // specified angle in radian
        double coshvalue = Math.Cosh(num1);
        Console.WriteLine("The cosh of num1 = " + coshvalue);

        coshvalue = Math.Cosh(num2);
        Console.WriteLine("The cosh of num2 = " + coshvalue);

        coshvalue = Math.Cosh(num3);
        Console.WriteLine("The cosh of num3 = " + coshvalue);
    }
}

Output: 

The cosh of num1 = 5.71003694907842E+25
The cosh of num2 = 1
The cosh of num3 = 1.54308063481524

节目 2:

c sharp . c sharp . c sharp . c sharp

// C# program to illustrate the
// Math.Cosh() Method
using System;

class GFG {

    // Main Method
    public static void Main(String[] args)
    {

        double num1 = (30 * (Math.PI)) / 180, num2 = 11.0, num3 = 45.0;

        // It returns the hyperbolic cosine of
        // angle in radian
        double coshvalue = Math.Cosh(num1);
        Console.WriteLine("The cosh of num1 = " + coshvalue);

        coshvalue = Math.Cosh(num2);
        Console.WriteLine("The cosh of num2 = " + coshvalue);

        coshvalue = Math.Cosh(num3);
        Console.WriteLine("The cosh of num3 = " + coshvalue);
    }
}

Output: 

The cosh of num1 = 1.14023832107643
The cosh of num2 = 29937.0708659498
The cosh of num3 = 1.74671355287425E+19
