Java Math sinh() Method

The sinh() method of Java Math class returns the hyperbolic sine of the specified double value.

Syntax:

public static double sinh(double x)

Parameters:

The parameter ‘a’ represents the number whose hyperbolic sine is to be determined.

Return Value:

The sinh() method returns the hyperbolic sine of the argument.

• It returns zero with same sign as argument, if the argument passed is zero.
• It returns infinity with the same sign as the argument, if the argument is infinite.
• It returns NaN, if the argument is NaN.

Example 1:

public class JavaMathSinhExample1 {
    public static void main(String[] args) {
        double a=30;
        //return the hyperbolic sine value for a
        System.out.println("Hyperbolic sine value : "+Math.sinh(a));
    }
}

Output:

Hyperbolic sine value : 5.343237290762231E12

Example 2:

public class JavaMathSinhExample2 {
    public static void main(String[] args) {
        //return the Hyperbolic sine value for Double.MIN_VALUE
        double a=Double.MIN_VALUE;
        System.out.println("Hyperbolic sine value for "+a+" = "+Math.sinh(a));
    }
}

Output:

Hyperbolic sine value for 4.9E-324 = 4.9E-324

Example 3:

public class JavaMathSinhExample3 {
    public static void main(String[] args) {
        // return an hyperbolic Sine value for PI
        double x = Math.PI;
        System.out.println("Hyperbolic Sine value for "+x+" = "+Math.sinh(x));
    }
}

Output:

Hyperbolic Sine value for 3.141592653589793 = 11.548739357257748

Example 4:

public class JavaMathSinhExample4 {
    public static void main(String[] args) {
       //returns NaN, if the argument passed is NaN or infinity
        double x= Double.NaN;
       System.out.println(Math.sinh(x));
    }
}

Output:

NaN

Example 5:

public class JavaMathSinhExample5 {
    public static void main(String[] args) {
       //returns zero with same sign as argument, if the argument passed is zero
        double x= -0d;
       System.out.println(Math.sinh(x));
    }
}

Output:

-0.0
