@p.s. Can you give more details please?

@John $0\le \alpha_i < \infty$. Yes, the infinite cone.

@JacquesUng You should accept this answer.

comment The Wicked Integral
I think it is very unintuitive that this is independent of $n$. It would be nice if someone offered an intuitive explanation of that fact.

I couldn't come up with a more specific title. I'm open to title suggestions.

@Dancrumb's comment has a lot of votes, it's confusing. I think the answer should be edited to clarify that no such assumption is made.

revised Prove that if $\frac{x+y}{3a-b}=\frac{y+z}{3b-c}=\frac{z+x}{3c-a}$ then $\frac{x+y+z}{a+b+c}=\frac{ax+by+cz}{a^2+b^2+c^2}$
Original title suggests that the equality holds always.

comment Geometry problem involving infinite number of circles
@KyleGannon I think that formalizing it is part of the problem. The figure has all the information you need.

comment Convergent or Divergent Integral
@CarlWitthoft The analytic antiderivative returned by Mathematica is somewhat complicated. In the particular integration range from 0 to 1 it simplifies to the result I posted. If someone does it by hand it would be welcome.
