1.题意:给一个函数F(X)的表达式,求其最值,自变量定义域为0到100 2.分析:写出题面函数的导函数的表达式,二分求导函数的零点,对应的就是极值点 3.代码: # include <iostream> # include <cstdio> # include <cmath> using namespace std; ; double Y; int sgn(double x) { ; ) ; ; } double F(double x) { )+)+)+)-Y*x;…

在区间(0,100).在恒大二阶导数0.f(x)有极小值.用的最低要求的一阶导数值点: #include<math.h> #include<stdio.h> #include<stdlib.h> #include<string.h> const double eps=1e-6; double f(double x,double y) { return 6*pow(x,7)+8*pow(x,6)+7*pow(x,3)+5*pow(x,2)-y*x; } dou…
