2010-12-22 19:09:42 +0100 | commented answer | Limitation of solve? @Jason: Mathematica had trouble with the simplified version? That's surprising. I wonder why, since sage had no problem with it. |

2010-12-14 20:24:21 +0100 | commented answer | Limitation of solve? This answer has already been extremely helpful, thanks. I guess at this point I'll have start using my brain as well as the computer to solve this problem :) |

2010-12-13 13:06:16 +0100 | commented question | Limitation of solve? Ah, much better. Thanks for the tip |

2010-12-12 23:34:42 +0100 | commented answer | Limitation of solve? Alright, I have updated and added the equations. Sorry, the simplified version was too simple so I put up the full version. |

2010-12-09 13:42:06 +0100 | commented answer | Limitation of solve? What other information about my problem would be useful? And I do need algebraic solutions, not numeric approximates. |

2010-12-07 23:21:47 +0100 | asked a question | Limitation of solve? I am using (or trying to use) the solve function to solve a system of 10 nonlinear equations in 10 variables. However, solve simply outputs the 10 equations after some time computing. Is this running into a limit of the solve function, or is there some other way to economize my input to make it more solve-function-friendly? Would it help to know the algorithm which solve uses? EDIT: At a suggestion from niles, I am putting up the equations that I am solving. I have a version that is simplified, but it is not a problem to solve. In the equations below it is legal to set any combination of the variables equal to zero, and the resulting solutions will be a subset of the solution set of the full collection of equations. For those who are curious, the simplified version is this set of equations with a, b, c, g, h, i, j == 0. If there is anything more that anybody would like to know about these equations or where I am getting them from, just say so in a comment. |

2010-12-06 21:53:32 +0100 | asked a question | Noncommuting variables I am extremely new to Sage, and even newer to this site, so I apologize if anything is not up to standards. I am dealing with a multivariable polynomial ring over $\mathbb{Z}$ with noncommuting variables. Is there a way to implement this with Sage? The closest thing I have found is FreeAlgebra, where the variables are noncommutative, but I have not found any way to impose relations that I want. As stated before, I am extremely new to all of this so don't assume that I know anything, and don't hesitate to give any and all suggestions. |
