| 18:15.47 | eightyeight | what is a good free software computer algebra system? |
| 18:16.38 | sinuhe | GNU Octave is probably overkill. |
| 18:17.18 | sinuhe | http://directory.fsf.org/category/math/ |
| 18:17.19 | eightyeight | why do you say it's overkill? |

| 18:17.55 | brac | [Octave] |
| 18:19.15 | sinuhe | eightyeight: I suppose it will do the job. It's overkill in that it's not like buying a graphing calculator. |
| 18:19.39 | eightyeight | i doubt it's overkill for what i'm looking for |

| 18:29.27 | acc_ | eightyeight: another good one is maxima |
| 18:29.39 | acc_ | http://maxima.sourceforge.net/ |
| 18:30.48 | acc_ | If you REALLY want to do open source math, you might want to consider SAGE: http://www.sagemath.org/ |
| 18:32.51 | acc_ | This page also gives a good overview of what's out there. Some software is better at certain things (e.g., numerical computation vs. symbolic manipulation). http://sage.math.washington.edu/home/wdj/sigsam/opensource_math.html |
| 18:32.52 | brac | [Open source mathematical programs] |
| 18:34.23 | eightyeight | acc_: looks like sage relies on gap? |
| 18:34.44 | acc_ | It's not all necessarily Free Software in the RMS sense, though (there's some BSD and MIT licensed stuff there), if being GPL-strict was one of your requirements. |
| 18:35.21 | acc_ | eightyeight: What do you mean by "relies?" |
| 18:35.37 | eightyeight | i'm not an rms fanboy |
| 18:35.44 | acc_ | It's one of the components, yes. |
| 18:36.00 | eightyeight | when attempting to install 'sagemath', it wants to pull down gap |
| 18:36.19 | acc_ | Yes, it's a dependency. |
| 18:38.16 | eightyeight | i have mathematica 5 for students, and i've called wolfram a couple times to get my license updated, and have not received a return call |
| 18:38.23 | eightyeight | so, screw em |
| 18:40.21 | acc_ | eightyeight: What are you taking this semester? |
| 18:40.50 | eightyeight | finishing up ode and linear algebra |
| 18:40.58 | eightyeight | dynamical systems and topology next semester |
| 18:42.15 | acc_ | eightyeight: do they make you decide on an emphasis in the undergrad program? |
| 18:42.32 | eightyeight | no |
| 18:42.51 | eightyeight | you can do applied mathematics or general |
| 18:42.55 | eightyeight | i'm going after general |
| 18:51.33 | eightyeight | acc_: you still have the math touch? want to help me see why i can't get the inverse laplace transform of a certain function? |
| 19:44.17 | acc_ | eightyeight: hmm I could give it a shot |

| 19:47.04 | acc_ | ah |
| 19:47.05 | acc_ | :) |
| 19:47.26 | acc_ | I only have maxima installed at the moment |
| 19:47.44 | eightyeight | i've moved on. if you have any insights in the algebraic magic to simplify it so i can easily see the properties... |
| 19:58.41 | acc_ | eightyeight: Are you sure that you copied that function down correctly and the denominator isn't s^2-2*s+1? ;-) |
| 19:59.49 | eightyeight | yes |
| 20:02.40 | eightyeight | yeah. completing the square in the denominator produces '(s-1)^2+1' which is fine, but the numerator is screwed up to get it nice |
| 20:08.30 | acc_ | 2*(s+1)-1 isn't workable? |
| 20:10.08 | eightyeight | hmm. didn't think of that. i kept staring at 2*(s+1/2). that might work out a bit easier... |
| 20:14.24 | eightyeight | would you look at that |
| 20:14.30 | eightyeight | acc_: thx. that was the trick |
| 20:15.25 | acc_ | eightyeight: np |
