comment Why is a linear autonomous system asymptotically stable iff for all eigenvalues $\lambda$ of $A$, $Re(\lambda) < 0$
Damn, unfortunately my knowledge of linear algebra ends at eigenvectors. In retrospect I probably should have mentioned that in the question.

comment A point minimizing total great circle distance to a given set of points on a hemisphere
@Rahul yes, now that you point that out, and specifically on the hemisphere, if that helps. I believe that a hemisphere guarantees that the geometric median will be unique, whereas on the sphere there could be an infinite number of points.

@Mark Sorry, but I don't understand. Can you dumb it down a bit :) ?

What is WAI? Is it a general trend that arbitrary pdf's are hard to solve? The question seemed so simple conceptually... I'm 2/2 now for getting unexpectedly difficult solutions to questions about conceptually simple pdf's.

Edited my question to clarify that I am asking about the case where $x$ is sampled from the uniform distribution on $[0,1]^d$. And, yes, I am asking about the density of $|x|$.
