comment How to export data in scientific form
I thought a similar thing is possible with CForm but I failed to set it as Listable.

comment Highlighting a single Period of a Trig Plot
Just plot a trig function two times, use different styles and ranges (PlotStyle and PlotRange, respectively). To combine two plots use Show function.

comment DSolve vs a system of differential equations
I've contacted Wolfram, the support team forwarded the issue to the developers. I'll let you know if I find anything new.

Yup, I stopped the evaluation after a few minutes.

comment DSolve vs a system of differential equations
I'd expect that DSolve will be able to crack this problem by itself. A system of 2 equations is just a toy model. If you consider more equations, things will not go so smoothly anymore. Anyway, I've sent a message to Wolfram, perhaps they will be able to help us.

comment ParallelEvaluate for function minimization
Minimization involves recursion-based algorithms. Parallelizing them might be challenging (I'm no IT expert though).

Ah, right. Thanks.

comment Cannot solve a system of 5 square-root simultaneous equeations
I thought that Reduce will also seek for an exact result, which in this particular problem might not exist.

comment DSolve vs a system of differential equations
This is very similar to the solution provided by @chuy (of course, both are very nice but they do not answer my question). We're putting f'[x] and g'[x] by hand. It's like one's doing all the work for Mathematica:-). Perhaps I will need to restate my question.

Fixed minor code inconsistencies.

comment DSolve vs a system of differential equations
That's a very nice cheat:-). It's practically the same as the solution provided by george2079 though.

comment DSolve vs a system of differential equations
Yup:-). The result is a confluent hypergeometric function. But it'd be great if Mathematica could do it by itself:-).

revised Efficient way of setting up a rule
Changed the rules (the method itself is ok, but the rules were incorrect)
