I disagree that national polls are worse than useless. They are very useful. National polls can tell you how states will poll and state polls will tell you how the national polls will go. It's virtually impossible to win the electoral college this year in any realistic way if you lose the...
As soon as I posted, I thought of a new way that seems to give somewhat reasonable answers, although they seem a bit off.
Because I'm not totally familiar with using Latex on this forum, here's a link to WolframAlpha Online to what I'm thinking: here.
D = Difference
M = Margin of error
I'm a bit of a polling junkie, and in general, I'm pretty good at math, but I can't figure this one out (at least, not yet).
As a concrete example, I'm going to use the latest Gallup survey:
Obama: 49%.
Romney: 44%.
Margin of error (95% confidence) = 2%.
As I've found out, the...
I have galaxies in the shapes of ellipses, and I have point sources around these galaxies. I need to find a formula to determine whether or not the point sources are within a specific galaxy or outside. It would be extremely simple with circles, but I can't figure it out with ellipses...
Hm, yeah, that makes more sense with incorporating the fact that it's off-center with the formula from this website:

I need to find whether or not a point is within an ellipse. The problem is that the ellipse is tilted at an angle and not at the origin. I've tried Googling everywhere and can't find a good equation for what I need. Does anybody know the formula for an ellipse that includes:
1. Coordinates...
