Sorry if this is in the wrong forum.
I have the equation [tex]r = \frac{a(1-e^2)}{1+e \cos \theta} [/tex],
and I'm wondering what the physical significance of the numerator is.
More specifically, what is 'a' (since e is what it usually is)?
I've seen various other representations with terms like angular momentum on the top (or rather h^2/GM).
In the context of what I'm doing, it's written this way to (presumably) uncover any implicity 'e'-dependence in the orbit.
