 Dec 27 comment Problem with a plot for 1D wave equation solution using NDSolve Here is the full code when I copied and pasted the full code into my notebook, I get syntax errors. Dec 27 comment Dynamic plot with synchronization of real time @Kuba I looked at updateInterval, but was not sure if it is more "strict" on getting timing exactly as needed than scheduled task. It says if possible, be done at least every t seconds. This whole subject of "real time" and Mathematica dynamics is very tricky. Dec 27 comment How does InternalPolynomialFunctionQ work? I doubt anyone can answer this, since it requires looking at the source code of the Wolfram Research Mathematica implementation of these algorithms, which only those who work at Wolfram are able to do. Dec 26 comment Can your Mathematica do the following integral? Here is a workaround, since it can do it term by term. f = (z - 2) PolyLog[2, z] Log[1 - z]/z^3;Simplify[Integrate[#, z] & /@ Expand[f]] !Mathematica graphics Mathematica seems to be really confused about something here. Dec 26 comment What's wrong with this while loop index definition? @Alyosha your code works. It makes indexed variables. Not a list. List uses [[ and indexed variables use [. Dec 25 comment Why won't something print with desired precision in a while loop? good example @MichaelE2, but this prints 100 digits: "Print[N[3.14100, 100]]" :) Dec 25 comment Why won't something print with desired precision in a while loop? Hard to say why without a MWE. It could be a bug, but hard to know. I tried this on 10.3.1 and it works: Print[N[Pi, 100]]. Can't you make a small example to show the problem? I just also add there might not be enough precision in the number itself. Dec 24 comment Saved InterpolatingFunction behaving badly is the m file so large that you can't simply post the relevant plain source code here? myself do not download attachment from strange web sites. Dec 24 comment Saved InterpolatingFunction behaving badly may be it is a bug. But to be able to make sure, someone needs to see your input file there. Dec 24 comment Bug: Wrong results from NSolve on coupled polynomials. WorkingPrecision->Automatic fails To send bug report, email support@wolfram.com, make sure you have self contained example of the problem in there and system specs. Dec 24 comment Bug: Wrong results from NSolve on coupled polynomials. WorkingPrecision->Automatic fails But I think the result, from same code, run on 2 different OS's should be the same. Changing WorkingPrecision -> 100 to make the result the same is really a workaround. For me, same code should give same output. Period. Else I would say it is a bug. But I am not an expert on this. Dec 24 comment Bug: Wrong results from NSolve on coupled polynomials. WorkingPrecision->Automatic fails I would think it is a bug. We have two different results on two different versions. One of them must be wrong :) Dec 24 comment Bug: Wrong results from NSolve on coupled polynomials. WorkingPrecision->Automatic fails I get the result shown in the post. windows 7, 10.3.1. screen shot: !Mathematica graphics and !Mathematica graphics Dec 23 comment How to calculate the pseudo-remainder and pseudo-quotient of two multivariate polynomials using Subscript makes the code very hard to read. I do not see what is the fascination with Subscripts really. Dec 23 comment Using a standalone CDF to replace a typical graphing calculator Here is a PocketCalculator at the demo site. One way you can do what you want without text input field, is to use pop-up menu and have pre-selected functions to choose from. Dec 23 comment Using a standalone CDF to replace a typical graphing calculator Yes it is possible. Any one can run any CDF, by using the player. But the free player do not allow non-numeric input in the input field. InputField as a control the user can type in a function into the field so this will not be possible. You'd need the pro CDF. Here is the chart how-player-pro-compares Look for the Keyboard entry to text fields entry. This requires the EnterpriseCDF version. Dec 22 comment Two-step web data submission It was not clear to me that you meant to use Mathematica for what you are doing, since I saw no Mathematica code posted and saw only HTML and Javascript. But that is fine. May be someone would know how to do this in Mathematica. Dec 22 comment Two-step web data submission I have the feeling you have posted this to the wrong forum. This forum is about the Wolfram Mathematica language, not Ajax and Javascript. Dec 21 comment Plotting two functions - one all the way to one point and other from that point on I think you need to use Piecewise but do not know W/ALpha myself. Dec 21 comment Solve equations and express with specific varible it is better to post the actual Mathematica plain source code you used. Also _ can't be used in variable names.
