Somewhat OT, but (maybe) interesting anyway? For a long time, I've been aware of the program Mathmatica (by Wolfram Research) that does a lot of math, including, iirc, things like symbolic integration and differentiation. (Everybody should have those capabilities at their finger tips ;-)
Anyway, my thinking on this topic is that I wouldn't mind having a program dedicated to the uses the OP brought up (I keep a session of bc - l open in a terminal for quick calculations). But I couldn't remember the name of the Mathmatica program (nor the guy who wrote it, who is fairly famous for it), so I went googling and came up with the following pages which reminded me of the name, but also pointed out that, apparently if you buy a Raspberry Pi, you get a free copy of Mathmatica. So, I will seriously consider buying a Raspberry Pi. (The (Wikipedia) pages listed below also give the names of various competitors to Mathmatica, including Mathcad -- disclaimer -- I've never used either of these programs, nor probably any of the others listed on these pages (but I didn't really look at the names of the other programs):) * [[https://en.wikipedia.org/wiki/List_of_computer_algebra_systems]] * [[https://en.wikipedia.org/wiki/Comparison_of_numerical- analysis_software]] On Wednesday, October 02, 2019 01:36:24 PM Nicolas George wrote: > David Wright (12019-10-02): > > > alias cp='cp -i' > > > alias rm='rm -i' > > > > Ouch, a couple of great recipes for losing information. > > Far better to train your fingers to spell cp and rm with five characters. > > Avoid assuming that everybody's mental process work the same as yours. > > Regards,
