yup
Oh whoops... I read that as .

I'm not sure what you did on this line, I'm guessing its in regard to the fact that Im(1) = 0
Also, did you mean:

If I am a conic section, then my e = ∞
Just so we don't have this discussion in the future, my definition of the natural numbers includes 0.
Sorry if I'm missing something obvious, but just to clarify
When you take the imaginary part of the sum of GP formula, does that instantly disregard the z^0 (=1) in the original series becuase Im(1) = 0? It seems weird because you use a = 1 for the formula, maybe I'm thinking about this too much haha

Is the answer ?
(I intend to post a writeup later)
Converting to polar form,
Since ,
The cosine function is even, so the first term on the LHS and RHS are equal. Cancelling,
Since the sine function is odd, for all .
And clearly this is only true when .
So therefore,

2u integration+circle geo
i made this question myself in paint so dont mind the bad production quality.
edit: look for the question which has the circle with one edge on -5 instead of -3. ignore the question where the circle touches -3.
