 1d comment Replacing the Slot in an expression In any case: have a look at MinimalPolynomial[]. 1d comment Replacing the Slot in an expression That's… not really how we think of slots; the indexing merely refers to the corresponding argument. So, #3 is a short way to refer to the third argument of a pure function. I don't think anyone here will fault you for using #1. 1d comment Replacing the Slot in an expression The #3 tells me that you do not have a simple Root[] object, but a "triangular" one obtained from not finishing the Gröbner basis reduction in full. Why not share the entire thing? Alternatively, you might first want to do a RootReduce[] to turn it into a simple Root[] object where all the slots are of the form #1 and the polynomial inside is really the minimal polynomial corresponding to the root. 1d revised “ReliefMap” and “ContourMap” unable to download error edited tags 1d comment Solve an inequality involving a sum with a parameter There isn't a closed form (no explicit way to express $n$ wholly in terms pf $p$), as I have previously said. 1d revised Evaluating documentation example crashes the kernel edited tags 1d comment Options for a function I define that can be passed to functions I call in the definition "should not" is a bit stronger than what I wanted to say; my only point was that this style looks to be difficult to maintain and can be easily broken during modification. The package is the classical way of having a few public functions that use private subroutines. 1d revised Is there a better way to get nice looking equations in output? edited tags 1d comment How to draw the pentagon or hexagon into the square size image Ah, so you want a pentagon/hexagon containing that image… look up Texture[] and VertexTextureCoordinates. 1d comment Efficient List of Lists @Marco, I forgot about that blog entry; thanks for linking to it. However, tip #3 seems to be becoming a bit less applicable with each new version, unfortunately. :( 1d comment How to draw the pentagon or hexagon into the square size image You want to inscribe a pentagon/hexagon in a square, then? How should it be oriented? 1d revised How to get partial results from Subsets[]? edited tags 2d comment Mathematica 10, Show, and PlotRange @Michael, I see… now that's quite annoying. I wonder if anyone's complained to WRI about this new behavior. 2d comment Why does the degree symbol disrupt this FrameLabel? I'm provisionally tagging this as a bug, but more confirmation from Mac users would be welcome. 2d revised Why does the degree symbol disrupt this FrameLabel? edited tags 2d comment Mathematica 10, Show, and PlotRange @Adam, your take-away from this should be "Show[] can be used to override previously set or default settings of Graphics[] or Graphics3D[]". 2d revised Plot list of million points edited tags 2d comment Multivariable Taylor expansion does not work as expected @David, you're right; I'll incorporate the fix later. Thank you! 2d comment 3D Gamma function Another possible workaround would be to reformulate your function entirely in terms of LogGamma[]. 2d revised 3D Gamma function edited tags
