Java Math.sinh() method

The java.lang.Math.sinh() is used to return the hyperbolic sine of a value. The hyperbolic sine of any value x can be defined as (e^x - e ^-x)/2, where e is an Euler's number.

Syntax

Parameter

Return

If the argument is positive or negative number, this method will return hyperbolic Sine value.
If the argument is Infinity, this method will return Infinity with the same sign as the argument.
If the argument is NaN, this method will return NaN.
If the argument is Zero, this method will return Zero with the same sign as the argument.

Example 1

public class SinhExample1
{
    public static void main(String[] args) 
    {
        double a = 30;
        System.out.println(Math.sinh(a));
    }
}

Test it Now

Output:

5.343237290762231E12

Example 2

public class SinhExample2
{
    public static void main(String[] args) 
    {
        double a = -1.0/0;
        // Input negative infinity, Output negative infinity 
        System.out.println(Math.sinh(a));
    }
}

Test it Now

Output:

-Infinity

Example 3

public class SinhExample3
{
    public static void main(String[] args) 
    {
        double a = Double.NaN;
        // Input NaN, Output NaN 
        System.out.println(Math.sinh(a));
    }
}

Test it Now

Output:

NaN

Example 4

public class SinhExample4
{
    public static void main(String[] args) 
    {
        double a = -0.0;
        // Input negative Zero, Output negative zero
        System.out.println(Math.sinh(a));
    }
}
