Plz, help me to debug my code!

Question

I'm not really good at C++ and not sure if this code is correct. Plz, help me to debug it

#include <iostream>
#include <math.h>

using namespace std;

int main()
{
setlocale(0, "English");
double A, s1, s2, y;
system("cls");
cin>>A;
cout<<"Input A:"<<A<<endl;
s1=sin(2*(A))+sin(5*(A))-sin(3*(A));
s2=cos(A)+1-2*pow(sin(2*(A)), 2);
y=s1/s2;
cout<<"y="<<y;
system("pause");
return 0;
}

This is what that code above should do https://www.dropbox.com/s/as8pw10gmlxbjjj/IMG_20210225_012032.jpg?dl=0
