F.

You're right )))))))my english isnt so good/

Would you be so kind to change algorithm for solving this system d2_x/dt_2=-GMx/(x^2+y^2)^(3/2) d2_y/dy_2=-GMy/(x^2+y^2)^(3/2) algorithm name is Runge-Cute Method #include <stdio.h> #include <stdafx.h> #include <math.h> #include <iostream> using namespace std; double f(int i,double x,double y[4]){ s...
