The asinh()
method computes the hyperbolic arcsine of the specified number and returns it.
Example
// hyperbolic arcsine of 5
let number = Math.asinh(5);
console.log(number);
// Output: 2.3124383412727525
asinh() syntax
The syntax of the Math.asinh()
method is:
Math.asinh(number)
Here, asinh()
is a static method. Hence, we are accessing the method using the class name, Math
.
asinh() Parameter
The asinh()
method takes a single parameter:
number
- whose hyperbolic arcsine is to be calculated
asinh() Return Value
The asinh()
method returns:
- hyperbolic arcsine of the given argument
number
- NaN (Not a Number) for a non-numeric argument
Example 1: JavaScript Math.asinh()
// hyperbolic arcsine of a negative number
let number2 = Math.asinh(-5);
console.log(number2);
// hyperbolic arcsine of zero
let number1 = Math.asinh(0);
console.log(number1);
// hyperbolic arcsine of a positive number
let number3 = Math.asinh(32);
console.log(number3);
// Output:
// -2.3124383412727525
// 0
// 4.15912713462618
In the above example, the Math.asinh()
computes the hyperbolic arcsine of
-5
(negative number) - results in -2.31243834127275250
(zero) - results in 032
(positive number) - results in 4.15912713462618
Example 2: Math.asinh() with Infinity
// asinh() with positive infinity
let number1 = Math.asinh(Infinity);
console.log(number1);
// Output: Infinity
// asinh() with negative infinity
let number2 = Math.asinh(-Infinity);
console.log(number2);
// Output: -Infinity
Example 3: Math.asinh() with Non-Numeric argument
let string ="Harry";
// asinh() with a string argument
let value = Math.asinh(string);
console.log(value);
// Output: NaN
In the above example, we have tried to calculate the hyperbolic arcsine value of the string "Harry"
. That's why we get NaN as the output.
