2012-02-23 11:48:32 +0100 | commented question | Solve non linear symbolic equation Yes I did try that. I realized that things need not be complicated. So I re-modelled my problem with some approximations and ended up with a simpler equation that sage could handle. But I don't know how to make approximations (like neglect all powers of a variable) and ended up doing that by hand. Is there any way to make sage do the approximations? |

2012-02-23 06:09:06 +0100 | asked a question | Solve non linear symbolic equation Hi, I want to solve a an expression (quiet long one involving trigonometric functions) which has a lot of symbolic parameters (8 to be exact) for x. It takes a lot of time (I didn't get an output after 45 mins). Is there any way for me to speed up things. I am sure my way is inefficient. |

2012-02-22 13:21:59 +0100 | commented answer | Extract solutions from solve @kcrisman Thanks a lot for that. Those semicolons come from C (and maybe a bit from Octave/Matlab). I just can't think of a world without semicolons. And like you said, a bit of Google and some docs would have answered me. |

Not at all! Likely you could have found this by doing a little more reconnaissance, but hopefully others in the same boat will now find this instead. Incidentally, I hope this example answers your questions. Essentially, Sage returns Python lists, and this is how to extract stuff from them. It returns a symbolic equality, and then the There is another way to get solutions as Python dicts, but that is slightly more advanced so maybe someone else can comment on that. |

2012-02-22 11:27:44 +0100 | asked a question | Extract solutions from solve I am new to sage. So, sorry if my question is trivial. How can I get the values of a solve operation. Say I have gives me something like How can I take the value 2 or 3 from that? Also, when I was trying to solve another equation (quiet a long one), I get the solution as What does that zero mean? |
