http://acm.hdu.edu.cn/showproblem.php?pid=1071 解一个给定三个点的坐标二次函数某区域的积分值. 设出方程之后高斯消元得到二次函数.然后再消元得到直线. 两次积分然后相减就可以了. 把自适应辛普森改成了传入函数指针的形式,有点多此一举. 可以这样做的原因,是因为这道题保证要求的区域都是在第一象限,否则不能直接定积分. 语言:G++ #include<bits/stdc++.h> using namespace std; typedef long lo…
[题目分析] 圆的面积并. 直接Simpson积分,(但是有计算几何的解法,留着flag). simpson积分,如果圆出现了不连续的情况,是很容易出事情的.(脑补一下) 但是没有什么办法,本来就是一种取巧的做法,还能指望这暴力积分做什么. [代码] #include <cstdio> #include <cstring> #include <cmath> #include <cstdlib> #include <map> #include &l…
