Math.Tanh()是内置的Math类方法,该方法返回给定双值参数的双曲线正切。如果给定参数为NaN,则结果将为NaN。
用法:
public static double Tanh(double num)
参数:
- num:它是要返回其双曲线tan的数字,并且此参数的类型为System.Double。
返回值:该方法返回num的双曲正切。类型System.Double。如果num等于NegativeInfinity,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。
例子:
Input : num = 60.0 Output : 1.0
以下示例程序旨在说明Math.Tanh()方法:
示例1:
// 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);
}
}
输出:
The tanh of num1 = 1 The tanh of num2 = 0 The tanh of num3 = 0.761594155955765
示例2:
// C# praogram 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);
}
}
输出:
The tanh of num1 = 0.480472778156452 The tanh of num2 = 0.999999999442106 The tanh of num3 = 1
