computer programing

use the 4th-order Runge-Kutta scheme. You must write a computer program that accepts as input the aphelion (farthest) distance the planet is from the sun in astronomical units (AU), the eccentricity of the orbit, , and how many orbits are to be calculated. With the help of the equations on the back, your code will solve the four ODEs above, plotting the position of the orbiting body (starting at the aphelion) as a function of time as it orbits counterclockwise about the sun
