Parameter(s):

p – It represents the value whose hyperbolic arc-cosine value to be found.

Return value:

The return type of this method is number, it returns the hyperbolic arc-cosine value of the given p.

Example 1: Find the acosh of numeric values

console.log(Math.acosh(1));

console.log(Math.acosh(-19));

Output

NaN
NaN
NaN

Example 3: Passing non-numeric values.

console.log(Math.acosh("Hello!"));
// Output: NaN

console.log(Math.acosh(1 + 4i));
// Outout: Uncaught SyntaxError: Invalid or unexpected token
