Java - Math sinh(double x) method

---

---

Description

The Java Math sinh(double x) returns 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 1

The following example shows the usage of Math sinh() method to get a hyperbolic sine value for a positive double value.

package com.tutorialspoint;
public class MathDemo {
   public static void main(String[] args) {

      // get a double number
      double x = 45.0;

      // convert it to radian
      x = Math.toRadians(x);

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

Output

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

Math.sinh(0.7853981633974483)=0.8686709614860095

Example 2

The following example shows the usage of Math sinh() method to get a hyperbolic sine of a negative double value.

package com.tutorialspoint;
public class MathDemo {
   public static void main(String[] args) {

      // get a double number
      double x = -45.0;

      // convert it to radian
      x = Math.toRadians(x);

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

Output

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

Math.sinh(-0.7853981633974483)=-0.8686709614860095

Example 3

The following example shows the usage of Math sinh() method to get a value of a zero double values.

package com.tutorialspoint;
public class MathDemo {
   public static void main(String[] args) {

      // get a double number
      double x = 0.0;

      // convert it to radian
      x = Math.toRadians(x);

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

Output

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

Math.sinh(0.0)=0.0
