StrictMath sinh() Method in Java
Last Updated :
30 Jul, 2018
The
java.lang.StrictMath.sinh() method is used to return the
hyperbolic sine of a double value passed as parameter to the function. The hyperbolic sine of x is defined by the formula
where e denotes
Euler’s number
Syntax:
public static double sinh(double x)
Parameters:The function accepts a single double value
x whose hyperbolic sine is to be returned by the function.
Return Values: This method returns a double value which is the hyperbolic sine of
x. The following cases are arises:
- The function returns NaN if the argument is NaN or infinity
- The function returns infinity with the same sign as the argument if the argument is infinite.
- The function returns zero with the same sign as the argument if the argument is zero
Examples:
Input : 0.7853981633974483
Output : 0.8686709614860095
Input : 4.0
Output : 27.28991719712775
Below programs illustrate the use of java.lang.StrictMath.sinh() method:
Program 1:
import java.io.*;
import java.math.*;
import java.lang.*;
class GFG {
public static void main(String[] args)
{
double x = ( 45 * Math.PI) / 180 ;
System.out.println( "Hyperbolic sine of "
+ x + " = " + StrictMath.sinh(x));
}
}
|
Output:
Hyperbolic sine of 0.7853981633974483 = 0.8686709614860095
Program 2:
import java.io.*;
import java.math.*;
import java.lang.*;
class GFG {
public static void main(String[] args)
{
double x1 = 180 / ( 0.0 ), x2 = 0 ;
System.out.println( "Hyperbolic sine of "
+ x1 + " = " + StrictMath.sinh(x1));
System.out.println( "Hyperbolic sine of "
+ x2 + " = " + StrictMath.sinh(x2));
}
}
|
Output:
Hyperbolic sine of Infinity = Infinity
Hyperbolic sine of 0.0 = 0.0
