2018-04-30 08:38:34 -0500 | answered a question | Make SageMath allow for Error of Mathematica Apologies for posting again but I figured out you can pass the option as a normal arguement so: does the trick and solve returns the solutions. Hope this helps someone else too. JasonK |

2018-04-30 06:45:47 -0500 | asked a question | Make SageMath allow for Error of Mathematica Hello everyone! I am currently trying on the interface of SageMath to Mathematica for the solution of polynomial equations and inequalities. Whilst doing that I came across an instance that is typical for Mathematica when solving systems of polynomial equation and inequalities. I tried to solve the system and Mathematica returned the error
and as a result Sage raised the error and returned no solution. I am trying to get solutions to the system: for the variables and a sample of the code for the solve is: Is it possible to make an exception for specific Mathematica errors so as to get the solution? Many thanks, Jason :) |

2018-02-12 05:31:46 -0500 | commented answer | Solving system of polynomial inequalities in SageMath 8.1 Dear Slelievre, Thanks for the reply. I am trying to install qepcad from the Sage Shell and when I type I receive and error saying: I had a look on the forum about similar issues and I found one (here: https://ask.sagemath.org/question/34267/installing-cryptominisat/) but I still no luck. Any ideas? Best, Jason |

2018-02-10 10:46:45 -0500 | asked a question | Solving system of polynomial inequalities in SageMath 8.1 Hi everyone! I am currently trying to use SageMath for the solution of a system of polynomial inequalities. In the first place based on the documentation and because solutions were returned I used the "solve" command and the "solve_ineq" command. However, when I tried to verify the answers with the one computed by Mathematica I realised the solutions were not the same. Is this a bug in the current version? Also, I am trying to do it the normal way by computing the CAD using QEPCAD but when I tried to replicate the example on the website I get the following error:
I am using SageMath 8.1 in Windows 7 64bit and jupyter notebook for interface that I call using the SageMath shell, if that is of any help. The system I am referring to is the following:
and using the following substitution:
The output of
is
Sorry for the long post but I would really appreciate and help with regards on how to solve such as system of inequalities and whether solve command has a bug? Best, Jason |
