acoshf() in C++

acoshf(): This is a build-in function in the library math.h.

This function required one parameter. It gets a parameter whose value is in the range [1, ∞). It returns the inverse hyperbolic cosine of the given value. If the value is less than 1 then it returns nan.

Parameters: 

__X: The value whose inverse hyperbolic cosine value to be fined. 

Floating-point value.

Syntax:

acoshf(__X)

For Example:

1. __X = 10.0

acoshf(__X) => It returns 2.99322

2. __X = 0.5

acoshf(__X) = > It returns nan.

Approach

C++

#include <bits/stdc++.h>
using namespace std;

int main()
{
    float x = 10;
    cout << acoshf(x) << "\n";

    return 0;
}
