Last Updated :
02 Feb, 2023
The sin() function is defined in valarray header file. This function is used to calculate sine of the value of each element in valarray and returns a valarray containing the sines of all the elements. Syntax:
sin(varr);
Time Complexity: O(n)
Auxiliary Space: O(n)
Parameter: This function takes a mandatory parameter varr which represents valarray.
Returns: This function returns a valarray containing the sines of all the elements.
Below programs illustrate the above function:
Example 1:-
CPP
#include <bits/stdc++.h>
using namespace std;
int main()
{
valarray<double>
varr = { 0, 0.25, 0.5, 0.75, 1 };
valarray<double> varr1;
varr1 = sin(varr);
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 0.247404 0.479426 0.681639 0.841471
Example 2:-
CPP
#include <bits/stdc++.h>
using namespace std;
int main()
{
valarray<double>
varr = { 1.2, 3.14, 5.0, 0.0 };
valarray<double> varr1;
varr1 = sin(varr);
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 :
0.932039 0.00159265 -0.958924 0
