comment When should I shift $a$ and $b$ in $\cfrac{x^2}{a^2}+\cfrac{y^2}{b^2}=1$?
@OfirSchnabel Oh. Then I probably made some mistake in the previous computations. Gonna try it now.

comment Origin of the Integral (Theory Behind It - How it came about)?
I'd suggest you to read Hairer/Wanner's: Analysis by It's History. - It will answer that in much more detail than anyone can present you here.

@Kyth'Py1k Well, we're here to help. Whenever the need comes, just ask for help. :-)

@Surb My friend said that in the context of algebraic geometry, anyone who had studied it would understand.

@Surb Notice that the level of this question is far beyond my usual questions. The answer provider even spoke about Hilbert's Nutella. Must be very profound indeed.

@Surb This is a question a friend of mine asked me to do: He's a PhD student in a nearby mathematics university but as he had no internet at the moment, he asked me to ask this for him via SMS, as I explained in the comment to the user who provided an answer. My friend told me that no additional motivation was needed and that he had a personal style of asking dry questions.

I asked this for a friend: He was having trouble with his internet connection and sent me the question via SMS. As you may have noticed, this is far beyond the level of my habitual questions. He said that your answer is satisfactory and told me to accept it.

comment Is the focal distance of $x^2+\cfrac{2y^2}{3}=8$ equal to $2\sqrt{-4}$?
@David Yes. For a minute, I made the mistake of thinking that the procedure I made would be obvious.
