 Jan 30 awarded Commentator Jan 30 comment Sphere inside cylinder vs polyhedra? This is for materials engineering, but I'm trying to figure out the maths (or physics?) behind it. By 'better hold' I mean 'better grip'. So more force would be required to dislodge with {polyhedra|cylinder} based on theorem <>. Hmm, thinking about it now, maybe it's a physics.stackexchange question? Jan 29 asked Sphere inside cylinder vs polyhedra?

Thanks @Goldy; pretty sure that's what I was looking for :) Jan 27 awarded Editor Jan 27 revised Efficient dynamic summation of list of numbers? edited title Jan 27 comment Efficient dynamic summation of list of numbers? If it is needed to reduce complexity; a third auxiliary structure $S_2$ can also be introduced holding the reverse sum; i.e.: $S_2=[S_0[k-1]+S_0[k-2], S_1[0]+S_0[k-3] +\cdots$] Jan 27 asked Efficient dynamic summation of list of numbers? Dec 5 awarded Popular Question Jul 6 answered Translating code into mathematical formula: conditionals Jul 6 comment Translating code into mathematical formula: conditionals I have received this solution over IRC, it is useful but being able to more explicitly do an if elif type thing would be better: $$d1 = myset_1, d0 = myset_0, dnp1 = \sum_{i >= 2} myset_i$$ Jul 6 asked Translating code into mathematical formula: conditionals Apr 18 comment Super logarithmic inverse of tetration +1 and accepted. Thanks for your help Apr 18 awarded Scholar Apr 18 accepted Super logarithmic inverse of tetration Apr 18 comment Super logarithmic inverse of tetration Apologies, it's 4AM here. Only after rereading your answer did I realise you were talking about super roots on the same paragraph that you discussed super logarithms. Apr 18 comment Super logarithmic inverse of tetration Thanks Andrew, I think that helped solve my problem. One question though: you mentioned that the inverse of $\bf{^2}{x}$ to be the 2$^{nd}$ super-root of $x$. Would my $\bf{slog^x_2}$ still satisfy?
