Java.lang.Math.sinh() Method

---

Description

The java.lang.Math.sinh(double x) the the hyperbolic sine of a double value. The hyperbolic sine of x is defined to be (e^x - e^-x)/2 where e is Euler's number.Special cases −

• If the argument is NaN, then the result is NaN.

• If the argument is infinite, then the result is an infinity with the same sign as the argument.

• If the argument is zero, then the result is a zero with the same sign as the argument.

The computed result must be within 2.5 ulps of the exact result.

Declaration

Following is the declaration for java.lang.Math.sinh() method

public static double sinh(double x)

Parameters

x − The number whose hyperbolic sine is to be returned.

Return Value

This method returns the hyperbolic sine of x.

Exception

NA

Example

The following example shows the usage of lang.Math.sinh() method.

package com.tutorialspoint;

import java.lang.*;

public class MathDemo {

   public static void main(String[] args) {

      // get two double numbers numbers
      double x = 45;
      double y = -180;

      // convert them to radians
      x = Math.toRadians(x);
      y = Math.toRadians(y);

      // print the hyperbolic sine for these doubles
      System.out.println("sinh(" + x + ")=" + Math.sinh(x));
      System.out.println("sinh(" + y + ")=" + Math.sinh(y));
   }
}

Let us compile and run the above program, this will produce the following result −

sinh(0.7853981633974483)=0.8686709614860095
sinh(-3.141592653589793)=-11.548739357257748
