C# |数学。Tanh()方法
数学。Tanh() 是内置的数学类方法，它返回给定双精度值参数的双曲线 tan。如果给定的参数是 NaN，结果将是 NaN。 语法:
public static double Tanh(double num)
参数:
num: 是要返回双曲正切的数字，该参数的类型是系统。双。
返回值:该方法返回 num 的双曲正切值。系统类型。双。如果 num 等于否定定义，则此方法返回-1。如果 num 等于 PositiveInfinity，则此方法返回 1。如果 num 等于 NaN，则此方法返回 NaN。 例:
Input : num = 60.0
Output : 1.0
下面的程序说明了数学。Tanh()方法: 程序一:
c sharp . c sharp . c sharp . c sharp
// C# program to illustrate the
// Math.Tanh()
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 tan of
// specified angle in radian
double tanhvalue = Math.Tanh(num1);
Console.WriteLine("The tanh of num1 = " + tanhvalue);
tanhvalue = Math.Tanh(num2);
Console.WriteLine("The tanh of num2 = " + tanhvalue);
tanhvalue = Math.Tanh(num3);
Console.WriteLine("The tanh of num3 = " + tanhvalue);
}
}
Output:
The tanh of num1 = 1
The tanh of num2 = 0
The tanh of num3 = 0.761594155955765
节目 2:
c sharp . c sharp . c sharp . c sharp
// C# program to illustrate the
// Math.Tanh() 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 tan of
// angle in radian
double tanhvalue = Math.Tanh(num1);
Console.WriteLine("The tanh of num1 = " + tanhvalue);
tanhvalue = Math.Tanh(num2);
Console.WriteLine("The tanh of num2 = " + tanhvalue);
tanhvalue = Math.Tanh(num3);
Console.WriteLine("The tanh of num3 = " + tanhvalue);
}
}
Output:
The tanh of num1 = 0.480472778156452
The tanh of num2 = 0.999999999442106
The tanh of num3 = 1
