 May16 revised Problem with simplifying Sinc function deleted 26 characters in body May16 comment The Orbit and Perigee of the Flamsteed comet "I'm not interested in copying the day of the perigee from any Internet sites" - I gathered that, but thanks for being explicit anyway. :D Well, let me dig up my ephemerides... May16 comment How to tell Mathematica to use Real Only Mode @bel, that or Plot[CubeRoot[x - 1], {x, -3, 3}]. I don't have version 9, but I'm guessing that's how it should now be done. May16 revised Plot cubic root which includes the negative graph added 270 characters in body May16 comment How to tell Mathematica to use Real Only Mode @bel, this might be a good time to use Surd[]/CubeRoot[]... May16 comment How can I substitute something using only map? Nevertheless, the last use of //@ just feels like using a pipe wrench to whack nails... May16 revised How can I substitute something using only map? deleted 14 characters in body May16 answered Problem with simplifying Sinc function May16 comment How can I substitute something using only map? Yes, they act quite differently; Map[f, {1, 2}] will apply the function f on the elements of the list {1, 2} to yield {f[1], f[2]}. That wors differently from Replace[{1, 2}, 1 -> 5, {1}] which replaces the 1 in {1, 2} with 5, to yield {5, 2}. May16 comment How can I substitute something using only map? "I think Replace is just a kind of syntactic sugar" - no. No, it's not. May16 comment A Symbol with Subscript and Superscript as an Axis Label "OK, I found the answer." - please write an answer to your own question. May16 revised Creating a NearestFunction that returns an index deleted 71 characters in body May16 revised Generating partitions of a set with a specified size of the parts edited tags May15 revised How to select elements from a 4D Array? added 8 characters in body; edited tags May15 comment Plotting points and functions in one graphic In the same vein as @george's suggestion: you could use Show[] to display the output of Plot[] and ListPlot[] together. May15 comment The Orbit and Perigee of the Flamsteed comet Yeah, that's why I left a comment and not an answer. The missing data in AstronomicalData[] is a sticking point, so if you're excluding the possibility of bringing in external data, then I'm not sure this is doable. May15 comment Solving homogeneous Fredholm Equation of the second kind Hmm, that's big. Your kernel's quite oscillatory too; There is a modification of Clenshaw-Curtis by Piessens and Branders for finite oscillatory integrals, which can be useful if you're taking the discretization route. You might want to look into that. May15 comment FourierSeries for rational function looks wrong Now that's just weird. Here we thought we don't have to add the assumption that the integration variable is within the integration interval... :D May15 revised Peirce's quincuncial projection bonus picture May15 comment How to simplify an expression with special functions to zero I daresay it is baffling that the usual approach of comparing LeafCount[]s doesn't work...
