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.

just curious, what exactly does 'beautiful mind' inspire and motivate? Battle against mental illnesses?

comment $\lim\limits_{n \to \infty} n \cdot\ln(\sqrt{n^2+2n+5}-n)$
It means that for $x \to 0$ $\log (1+x)$ grows at roughly the rate of $x$. You can get it using Taylor series.

comment Find summation of following series.
This is called 'closed-form expression', i.e. a function only of $n$. To get help I suggest you show some of your work first.

comment Find summation of following series.
do you mean 'closed form' or 'write it in one expression'?

comment Limit Question: lim theta---> 0 sin theta / 3 theta + tan theta: When you multiply 1/ cos theta by 1/ theta why doesn't your value change?
What you probably mean is why you can rewrite $\lim_x \frac{\sin x}{x \cos x} = \lim_x \frac{\sin x}{x} \lim_x \frac{1}{\cos x}$. This is because both limits exist and are finite.

comment How can I prove that “n is not O(1)”?
LHS is unbounded. RHS is bounded. Hence...
