You may contact me at: BelisariusForSO@gmail.com

But please don't email me with requests about Q&A. Post them in the site instead.

Infix should be used only where it is essential... like in "feliz año nuevo" @rm-rf

comment Plotting solutions of differential equations with different parameters
Cont .-- It's just that we've all been there once upon a time and we know that no matter the pressure you can be under, it's better for the student to be able to think out a solution. Not the better, not a perfect one, just a solution that works and can make him/her confident.

comment Plotting solutions of differential equations with different parameters
@Lawerance I posted yesterday some comment about your homework. Please don't take it personally. There's some kind of agreement on this site about what kind of help we should offer to homework tasks. While asking for some specific detail about Mathematica here for completing your HW is almost always considered OK, asking questions that (one way or another) imply "do it for me" are frowned upon. And that's not a vigilante pose.

@rm-rf Hey! I learned the meaning of protracted. Let's call it a day.

I can't find a question showing the differences between using Evaluate[f[x]] and the Option Evaluated -> True ... but it's out there. Who can find it?

comment I'm trying to filter a date range by day of month and day of week - what am I doing wrong?
Welcome to Mathematica.SE! I suggest the following: 1) As you receive help, try to give it too, by answering questions in your area of expertise. 2) Read the faq! 3) When you see good questions and answers, vote them up by clicking the gray triangles, because the credibility of the system is based on the reputation gained by users sharing their knowledge. Also, please remember to accept the answer, if any, that solves your problem, by clicking the checkmark sign!

Think of patterns like regexes. Your expression isn't "equal" to a regex. Your expression "matches" it.

This isn't quite right. Please check @Szabolc's comment under your other (identical) answer mathematica.stackexchange.com/a/43310/193

Haven't see it before. Very nice

comment Does RandomInteger[{0,n}] disfavor n?
No, I tried to show that the perceived effect is a histogram device. BTW ... If you don't use @userbame the other party doesn't get pinged, but I know you know

No: p = Table[RandomInteger[k, 100000], {k, 10, 100, 10}]; ListLinePlot[ Mean@Most[#/Last@#] &@Sort[Tally@#][[All, 2]] & /@ p, PlotRange -> {0, 1.2}]

comment How to find the zeros of a Complex trigonometric function
In case you didn't know, you can format your code better by putting four spaces at the front of every code block (or click on the curly-brace button above the question editing area). Further, wrap short inline code snippets in a pair of backticks ``. This will make your post easier to read.

comment Solve equation with two different sets of replacement rules
As in eqn = c0/(c0 + cs) == Iunk/Is; s = Solve[eqn, c0][[1]]; subsCoke = {cO -> c0, cs -> 2, Iunk -> 0.3995, Is -> 0.7339}; subsPepsi = {c0 -> c0, cs -> 2, Iunk -> 0.3915, Is -> 0.7645}; {s /. subsCoke, s /. subsPepsi}

The usual way is to solve it once and then use the reprules:
