C# Math.Cosh()用法及代码示例

Math.Cosh()是内置的Math类方法，该方法返回给定双值参数的双曲余弦值。

用法:

public static double Cosh(double num)

参数：

num:它是要返回其双曲余弦值的数字，并且此参数的类型为System.Double。

返回值：该方法返回num类型为System.Double的双曲余弦。如果num等于NegativeInfinity或PositiveInfinity，则返回PositiveInfinity。如果num等于NaN，则返回NaN。

例：

Input   : 60.0
Output  : 5.71003694907842E+25

以下示例程序旨在说明Math.Cosh方法：

示例1:

// 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); 
    } 
}

输出：

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

示例2:

// C# praogram 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); 
    } 
}

输出：

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