comment How to display line numbers in the Mathematica?
" Okey, Now please answer my question!" sounds like an extremely rude way to address someone who is welcoming you

comment How to write the following subroutine in Mathematica and then how to call it?
You should learn at least the very basic syntax rules before asking

comment Piecewise function and integral function
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!

comment Does RegularExpression support “(?R)”?
@2012rcampion Googling for "PCRE palindrome" you'll find a lot of equivalent regexes. Some of them do work in Mathematica and others don't. I guess that depends on the PCRE version

You'll need a Button or similar to indicate that the user interaction with the CheckboxBar[] has finished

comment Maximize[Cos[x - 1], x] is not evaluated
Also, if you try to "calculate" the period for Sin[x] as Solve[f[x + k] == f[x] && k != 0, k] it doesn't work in a straightforward way because ArcSin[Sin[x]] does not simplify as x

comment Animate point go round a triangle
I second @Mr.Wizard because your contributions to the site are very well received. It wouldn't matter if you were the standard "novice new user type", but you aren't. And it's a lame to have that kind of confusion among two good site citizens. Please don't forget to try changing you user name once the site allows you.
