I'm a postdoc at LIUM in France, working in Machine Learning (statistical machine translation), although my thesis was on mathematical analysis of Evolutionary Algorithms (EAs), therefore my skills revolve around probability, Markov chains, calc/analysis, asymptotics and a bit of combinatorics.

I'm here mostly to learn and improve my skills, so please don't expect much rigor or proficiency from me.

This is my Academia profile if you are interested in my work for some reason.

comment Calculate summation of square roots
the easiest way is to use the Euler-Maclaurin formula for integrals and sums or just compare to the corresponding integral. There's not 'closed-form solution'.

revised $f$ is uniformly continuous $\Leftrightarrow$ $\mathrm{Re}f$ and $\mathrm{Im}f$ are uniformly continuous.

are you kidding? You gave them yourself! Third line of your question.

@AndréNicolas: this is exactly what i did in my answer!

It's because you don't want the result to depend on either x or y

@AndréNicolas: are you sure about bounds on $y$? It should be larger than $x$.

comment Calculate the expected value
you can change the bounds of integration: either $0 <x <1 \cap x < y<1$ or $0<y<1 \cap 0<x<y$, just make sure the last integral you solve is bounded between 0 and 1

comment $\displaystyle \lim_{x\rightarrow 5}x^2=25$
I think your (a) is a bit of an overkill: it enough to take the upper bound on $x: |x+5|<|6+5|=11$

comment $\int \frac{1}{y-1} dy = \ln |y - 1|$?
1)it should be $\log|y-1| +C$, 2) real log function is defined only for positive arguments
