JavaScript Math sinh()

sinh() Syntax

The syntax of the Math.sinh() method is:

Math.sinh(number)

Here, sinh() is a static method. Hence, we are accessing the method using the class name, Math.

sinh() Parameter

The sinh() method takes a single parameter:

• number - whose hyperbolic sine is to be calculated

sinh() Return Value

The sinh() method returns:

• hyperbolic sine of the given argument number
• NaN (Not a Number) for a non-numeric argument

Example1: JavaScript Math.sinh()

In the above example, the Math.sinh() method computes the hyperbolic sine of

• -1 (negative number) - results in -1.1752011936438014
• 0 (zero) - results in 0
• 2 (positive number) - results in 3.626860407847019

Note: Mathematically, the hyperbolic sine is equivalent to (e^x - e^-x)/2.

Example 2: Math.sinh() with Infinity Values

Example 3: Math.sinh() with Non-Numeric Argument

In the above example, we have tried to calculate the hyperbolic sine value of the string "Harry". That's why we get NaN as the output.
