Emacs' calc can also be surprisingly powerful. Not quite at the level of Maxima, but still perfectly capable of basic symbolic algebra and calculus, arbitrary precision arithmetic, linear algebra, and other good things.
I use it quite heavily since it's right there in my editor. It's kind of like a good-enough phone camera that's always close at hand vs. a dedicated camera that's better but takes more effort to have ready.
- pmiller2 10y agoThat's neat. I had no idea calc could do calculus!
- a_e_k 10y agoIt can indeed! Adapting the first example from the article, in Emacs type: M-x quick-calc RET integ(exp(-x^2),x) RET You'll see that it immediately responds back with: erf(x) sqrt(pi) / 2
- agumonkey 10y agoI always facepalm when I do math outside of Emacs. Calc was never really advertised, it's not a toy. Also I've heard it might be scraped from vanilla emacs and made into an extesion, but I may be confused.
- 50CNT 10y agoThe Emacs Wiki does describe it as the "poor man's Mathematica". Org-tables with Calc functions are also quite nice.
