Question

write c++ program for the function((a+b)^4 - (a^4+4a^3b + 6a^2b^2)/(4ab^3+b^4)), at a=1000, b=10^-2,10^-3,10^-4

Answer 1

#include<iostream>
#include<math.h>
using namespace std;
& double f(double a,double b){
double c;
& c=pow(a+b,4)-(pow(a,4)+4*b*pow(a,3)+6*pow(a,2)*pow(b,2))/(4*a*pow(b,3)+pow(b,4));
return c;
}
int main (){
double a,b;
a=1000;
b=pow(10,-2);
cout<<" a=1000, b=10^-2& : "<<f(a,b)<<endl;
b=pow(10,-3);
cout<<" a=1000, b=10^-3& : "<<f(a,b)<<endl;
b=pow(10,-4);
cout<<" a=1000, b=10^-4& : "<<f(a,b)<<endl;

system("PAUSE"); &
