acos源码编辑

acosԴ??༭

我把源代码也放出来：

#include<iostream>

#include<cmath>

#include<cstdio>

#define PI acos(-1)

using namespace std;

int main()

{

double a1 = 4;

double a2 = 2;

double x = 0;

double y = 0;

x = (pow(a1, 2) - pow(a1, 2) * PI / 4 + pow(a1, 2) * PI / 4 / 3 - a1 - 2 * (sqrt(pow(a1, 2) - pow(a2, 2)) - 2)) / 2;

y = pow(a2, 2) - pow(a2, 2) * PI / 4 - x;

double s = fabs(x - y);

printf("%.4lf\n", s);

return 0;

}
