Hi,
I think this is not homework - it's a general problem applyed to orbits.
I want to build an ellipse given the minimum n points (x,y) knowing that one of the focus (barycenter) is (0,0) - the other one can be elsewhere. My questions are:
1) How many points are needed? A unique ellipse needs five points. But in this case we know the focus.
2) How do I calculate the formula of that ellipse? Is the polar form more adequate?
3) How do I calculate the inclination of the major axis regarding the x axis?
Please give me - only if possible - the complete solutions; I'm a little bit lost here...
Kind regards, and thanks,
CPtolemy
