The asin() function is defined in valarray header file. This function is used to calculate arc sine of the value of each element in valarray and returns a valarray containing the arc sine of all the elements.

Syntax:

asin(varr);

Parameter: This function takes a mandatory parameter varr which represents valarray.

Returns: This function returns a valarray containing the arc sine of all the elements.

Below programs illustrate the above function:

Example 1:-




// C++ program to demonstrate
// example of asin() function.
  
#include <bits/stdc++.h>
using namespace std;
int main()
{
    // Initializing valarray
    valarray<double>
        varr = { 0, 0.25, 0.5, 0.75, 1 };
  
    // Declaring new valarray
    valarray<double> varr1;
  
    // use of asin() function
    varr1 = asin(varr);
  
    // Displaying new elements value
    cout << "The new valarray with"
         << " manipulated values is : "
         << endl;
  
    for (double& x : varr1) {
        cout << x << " ";
    }
  
    cout << endl;
  
    return 0;
}

Output:

The new valarray with manipulated values is : 
0 0.25268 0.523599 0.848062 1.5708

Example 2:-




// C++ program to demonstrate
// example of asin() function.
  
#include <bits/stdc++.h>
using namespace std;
int main()
{
    // Initializing valarray
    valarray<double>
        varr = { 0.2, 0.14, 5.0, 0.0 };
  
    // Declaring new valarray
    valarray<double> varr1;
  
    // use of asin() function
    varr1 = asin(varr);
  
    // Displaying new elements value
    cout << "The new valarray with"
         << " manipulated values is : "
         << endl;
  
    for (double& x : varr1) {
        cout << x << " ";
    }
  
    cout << endl;
  
    return 0;
}

Output:

The new valarray with manipulated values is : 
0.201358 0.140461 nan 0
