Answer 1

a)
#include <iostream>
#include "math.h"
using namespace std;
int main()
{
const double Pi = 3.14;
double x,y;
cin >> x;
y=((2*pow(sin(x),2))/(Pi*x)-atan(x));
cout << y << endl;
}
б)
#include <iostream>
#include <cmath>
double log(double a, double b)
{
return log(b) / log(a);
}
using namespace std;
int main()
{
double x,y;
cin >> x;
y=log(5,abs(x-12.5*pow(x,9))+((2*x-4)/(abs(pow(x,8)-12*pow(x,4)+5.1*pow(x,3)))));
cout << y << endl;
}
