Okay, so for this problem, i had a little bit of trouble with it.
00:06
And so i looked up, i googled a perihelian.
00:09
And apparently there's a formula that maybe we were supposed to know.
00:12
So the perihelian of 1 is equal to a times 1 minus my eccentricity.
00:21
My aphelian 520 is equal to a times 1 plus my eccentricity.
00:29
So as far as coming up with equations to solve this, the first thing i did was i added them together, the two equations.
00:43
And so that gave me 521 is equal to 2a.
00:50
And then the top equation had negative a, e, the bottom one had ea.
00:56
So my a value is equal to 521 divided by 2.

That's just a start to coming up with an equation for this ellipse...
