using namespace std;
void main()
{
const float e = 0.000001, pi = 3.14;
float x, s, pr;
int n = 1;
cout<<"Input x: ";
cin>> x;
pr = x;
do{
s = pow(x, 2) / (pow(n, 2) * pow(pi, 2));
pr *= (1-s);
n++;
} while (fabs(s) > e);
cout<<"Result 1 = "<< sin(x) < cout<<"Result 2 = "< cout<<"Iter = "<< n < system("pause");
}
