comment Is it A Good Idea To Write Papers With Mathematica?
@3Sphere: Notebooks are plain text files, so can be treated like source code. Turn off FileOutlineCache and TrackCellChangeTimes and it then plays with version control quite nicely.

@Ben: I agree that vendor lock-in is a problem, but it isn't so much of a problem now that there is the free CDF player, which can read notebook files.

comment Inverse of the polylogarithm
@Sasha: You're probably (almost certainly) right about non-integer $n$, but more often than not, the integer case is the one that occurs. In particular, my question asked about the inverse dilog separately from the general polylog.

comment Finding General Expression from recursion
A hypergeometric function can be defined as a exponential generating function of a hypergeometric series. This does not really correspond to what you have above... Although, maybe you mean something different. (Also, these types of comments aren't really appropriate as answers in this site)

comment Optimal Towers of Hanoi strategy (3 pillars, from pillar A directly to C not allowed)
@Brian: Oh yeah. I guess that means my brain has stopped working for the night and it's time to go to bed. Sorry about the confusion.

comment Optimal Towers of Hanoi strategy (3 pillars, from pillar A directly to C not allowed)
What do you mean "It is not allowed to move a disk from pillar A to pillar C directly"? The second move has to be from A to C, at least in the Tower of Hanoi that I know... By the way, this is a classic problem and the linked to wikipedia article has lots of spoilers. I suggest you don't look past the introduction.

comment Finding General Expression from recursion
Your new edit is a very special choice of $P_1$. It's equivalent to choosing the initial condition $P_{-1} = 0$ (and $P_0$ unfixed)...

The naive, analytic continuation approach to "fractional" calculus is the best! (I use it all the time in dimensional regularization)

revised How to solve this integral of trigonometric f in Mathematica
The original question http://math.stackexchange.com/revisions/91100/1 looked different from the previous edit. Also, I assumed that the final y3 was meant to be y4

comment Transcendental Equations, Matrix (Eigenvalue problem?) (Mathematica)
@dunks: Not looking good. At the end of your code (removing the MatrixForm), try dbqs = Det[10^-15 bqs];Plot[Evaluate[Table[Tooltip[dbqs, e11] , {e11, .01, .2, .01}]], {ar, 0, .01}] You'll see that the Det[] always seems to be negative. In general, the expression is a bit messy, but it might be possible to prove this. Since you say that the Det should not be zero, I guess you've made a mistake somewhere.

comment Do complex numbers really exist?
@stevenvh: Exactly the same representation works, it's just harder to visualize a 4D space!
