comment Need hints on how to start on this?
What have you tried? What is $\epsilon$, what is $\delta$?

As your final result? No. I can extend my answer.

That is correct.

comment Find the probability that $X$ is even when following a geometric distribution
With $0<s<1$ we have $\sum_{n=0}^\infty s^n = \frac{1}{1-s}$. In our case, we have to adjust the formula, as we start at $n=1$ and not $n=0$.

The $n$ should not be there in your formula, if you apply the geometric sum up to infinity.

Just a quick info, typing help ss or doc ss in the command line might give you some hints.

comment Fast projection of multiple points on a line
Thanks, but I think for an efficient computation, the first approach is faster, since I only need two matrix-vector multiplication (assuming that $s$ is normalized).

comment Regularity of the function $|x|^ax$
You might want to check the cases in your first equation, there should probably be $a<0$ once.

comment How to solve this limit, normal methods result in zero. Online sources say otherwise.
Are you sure this is posted correctly? Because the limit is not 3/2 for your question.

comment Solve integral including Bessel function numerically in matlab
I tried you code and it works, however using quadgk instead of integral seems to be 10x faster (I used Matlab 2014 and performed the computation 50 times). However, the results vary (difference is 1%) and both calculation yield warnings.
