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 $(e^x-e^-x)/2$ where e denotes Euler's number
Syntax:
Java
Java
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
