comment Speeding up this recursive function
I can make it slower by changing Xmn[m] to Xmn[m,n].

comment How can I group constants/parameters using Mathematica?
I am going to keep my clothes on, but my answer in this question attempts to answer this problem.

comment Why does Mathematica spit this back out?
You could put a Assumptions -> a > 0 as an option.

Any chance of version 9 compatibility?

comment Visualising a 1-(50,15,15) design
So you want something like a Fano plane illustration but with 50 points and 15 of those on each "line"? Sounds challenging. Can you provide the actual block design?

comment How to remove Conjugate when it appears in a real-valued expression?
There is always /. Conjugate -> Identity. Use at your own risk.

comment Timing of associated Legendre polynomials
On my version 9 on windows, it takes no time at all to calculate any of those.

comment Show[cp1,cp2, …] but PlotLabel in cp2 does not show up
You can put the PlotLabel as an option to the Show rather than the ContourPlot.

comment How can I tell why Mathematica returns no solution to this system of nonlinear equations?
You need to clear your values for b, c and s.

comment How can I tell why Mathematica returns no solution to this system of nonlinear equations?
If you throw Eliminate at your equations, it says that s has to be 1/2.

comment How to speed up an optimization with very long symbolic expressions?
A 600 MB file is a little ridiculous. You could 7zip that down to 8 MB. I'd also recommend losing the Greek letters to save space.

comment Recurrence relation for multivariate polynomials
Maybe I am missing something, but do you just want $x_1^\text{# of 0s} x_2^\text{# of 1s}$?

comment Problem with “Lighting” in Mathematica V9
You can use RasterSize -> 2000 as an option in Rasterize. But it still doesn't look that flash. Jens' solution looks better.

comment How to draw a protractor in Mathematica
May I suggest using a relative font size? Instead of something like Style[#, Larger], I like to use Style[#, FontSize->Scaled[0.02]. It makes it easier when resizing and exporting graphics.

There is also this.

comment Why does the degree symbol disrupt this FrameLabel?
The "C" is where you would expect it on mine (windows v9.0.1).

comment Why does the degree symbol disrupt this FrameLabel?
It works fine for me, but you could try an ImagePadding option in the Plot. Given that you don't have a Frame -> True are you sure this is exactly what you are doing?

comment Is it possible to solve a certain set of nonlinear equations in Mathematica?
I am not convinced that's an actual solution, it's just pretty close to zero given your numerical accuracy.

comment FullSimplify wrongly reduces expression to zero
Same result on windows 9.0.1. Also Table[FullSimplify[Exp[-k (i - 0.5)^2]], {k, 73, 74, 0.01}] gives fun results.

comment What is wrong with this simple FindRoot?
Because you spelled Evaluate wrong?
