certainly if you calculate the maximum points in a parabolic motion for different values of angles, and join these points, the curve obtained is part of an elliptic curve. my question is: is there something else to hide the fact that the union of all these points as a result of this characteristic curve? or is it mere coincidence?

This question doesn't make sense in its present form; closing. – Noldorin Jan 20 '11 at 1:30
I agree with Noldorin, but there may indeed be a good question in there somewhere, so if OP makes some good edits I'd be inclined to vote for re-open. – Colin K Jan 20 '11 at 3:03
my question is clear and precise Noldorin: if you link all the maximum points for each curve of each release, I get as a result of an ellipse ask that this curve is an ellipse has something to do with the nature of the release? or is it mere coincidence? Noldorin if you understand now! – Jorman Sandoval Jan 20 '11 at 3:26
I would like to take a moment to think about what I'm trying to ask – Jorman Sandoval Jan 20 '11 at 3:28

No strong opinion on whether this question should be open or closed, but I don't think it's obvious that the question of whether a mathematical fact is a "mere coincidence" is ill-posed or uninteresting. To take a trivial example, suppose that you didn't know about energy conservation. You might notice the mathematical fact that $v^2/2+gh$ was a constant for a projectile. Until you had derived energy conservation, you'd call that a coincidence; afterwards, you'd realize it wasn't. (Granted, that example's a bit stupid, but I hope the point makes sense.) – Ted Bunn Jan 20 '11 at 15:28

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
