Detect Standalone CDF vs Browser Plugin environment I do not understand the question. Are you asking how to find out if CDF plugin is installed in the browser? If so, yes, you can check for that (using Javascript, inside the HTML page itself ofcourse). If you asking for something else, then I am not sure I understand then. |

Coloring Points in a Plot, based on their position in the list Your code does not run. Please post code that runs. Range::range: "Range specification in Range[1+n] does not have appropriate bounds." You also have an extra , in your position list at the end |

How can I create an advanced grid interface on Mathematica? it says in the link you have up there that the code can be shown here if asked for it: The more general code of a grid with sliders can be supplied. Ask a question on stackexchange and I'll post the code. so may be you can ask the author? |

How can I create an advanced grid interface on Mathematica? I do not see now why, at least the sorting of columns, by clicking on the top of top by having a pull-down menu which gives some options to do on the column data, can't be done with Dynamics as well. |

How stretch curly brace on multi-line text? +1 for the effort. But too much more complicated than simple latex , screen shot !Mathematica graphics I like M very much, but for computation and analysis. But for typesetting math, too much effort. I use SW, which is a latex GUI front end. $$ \begin{cases} x = & 1+t \\ y = & 1-t^2 \end{cases} $$ .ps I am not expert in Latex either. |

Why does the first derivative of a piecewise continuous function turns out with discontinuities? oh no, not the the famous missing @Evaluate again! !Mathematica graphics I am starting to think that M should issue an additional warning message each time Plot is used, saying "did you remember to use Evaluate? " |

How stretch curly brace on multi-line text? in the basic typesetting palellet , there is an option for doing this. But the left braces do not stretch with content. So not useful. see screen shot !Mathematica graphics Click on that, when in text cell and fill in the cells there. |

Identical code, different answers? If r1 and r2 where the first and second results, I am having hard time showing they are same result. Tried Reduce[r1-r2==0,Integers] and FullSimplify[r1-r2] , what would be the best way to show these are result but different form? |

Running a Numerical Simulation on a System of Differential Equations with unique initial conditions You say As such, the initial condition is over a period of time and not instantaneously at the start as would be normally expected? I never seen this before. How can initial condition be over period of time? We always write $y(t_0)=...$ where $t_0$ is just one value, i.e. instance of time. Do you have a reference for this sort of differential equation where initial conditions is defined over longer time than just an instance of time? Why not then take the end of this initial period as the real initial time for solving the ODE? |

Running a Numerical Simulation on a System of Differential Equations with unique initial conditions I do not understand your code syntax. What are these brackets for g there? They look strange and never seen them before. |

Why won't ContourPlot accept a variable argument? You did not show what const is. But either way, try ContourPlot[Evaluate@equations, {x, -1, 3}, {y, -1, 3}] do ??ContourPlot Attributes[ContourPlot]={HoldAll,Protected,ReadProtected} |

Integration gives ComplexInfinity when it shouldn't @SanderHeinsalu, not sure now. But can you please replace l with say z ? Hard to read l as it looks like 1. Not good idea to use l as variable name, it looks lik1 one on the screen. I replaced your l with z in my answer. |

Integration gives ComplexInfinity when it shouldn't @user2137029 the assumptions you used should have been at least positive integers in the hope to get same result. You used assumptions that k was Real. This is not the same. But as you can see, even using this more restricted assumption, did not help. |
