Hi /sci/, /g/ here.
I want to learn a computer algebra system. Which are the better ones that respect my freedom?

Free ones are all pretty bad unless you use them for simple shit.

If you want to use what real mathematicians use, get Maple. I see Maple at biggest math departments and it's in most of the papers.

No, academia is all about freedom as in copy-center. You publish and people are free to do whatever the fuck they want to do with it; for free or for profit. If you say/write something and put it into the public domain, does anyone that DARES quote with you with proper attributions STEALING your words and RIPPING you off because their work is pay-walled or book is copyrighted and for sale? Hell no.

GPL is a club that gives free access only to people that agree to join that club and refuse outsiders the same freedoms. The same can easily be said about any authoritarian group.

Clearly you've never read or comprehended the GPL license.

"You're free to use it if and only if you join our group and and force other to join to use your work" is not freedom. "You're free to use it for whatever" is not restricting your rights and freedom.

I could coax it to give the answer if I entered the expression termwise, and replaced n with floor(n) since otherwise it thinks that n is a real number and it will return remainder+fractional part for a real number.

Though I could get it to reduce each term, the sum of terms were beyond it to reduce, which is a funny restriction. In fact I gave it the arithmetic expression omitting the constant 1 and it could reduce it. But it couldn't reduce the whole expression. So this works, if you remove the constant:

p : 4*floor(n) + 1;
expand(mod(p*p-1, 8));

ridiculous

>>6532132
>replaced n with floor(n) since otherwise it thinks that n is a real number
I think it is possible to write declare(n, integer) to tell Maxima that n is integer. I don't know if the simplifier uses that information.

reduce does the simplification without any coaxing. Maybe pari/gp too since it is supposed to be used for number theory.

>> No.6532245

>>6532236
Declare does help to replace floor(n), but it still chokes on having a constant term for some reason. I am very surprised that it can't auto-reduce expressions when each subterm is reducible:
mod(a+b, n) = mod(mod(a, n)+mod(b, n), n)

>> No.6532252

>>6532245
Maybe it needs some special command.
For example if you declare(n, integer) and try to simplify exp(%i*2*%pi*n) it only seems to work with trigrat.

It was more or less fine as it was, except medicine (and pharmacology etc) should have been moved to low tier. I cannot fathom how anyone thinks medicine is better than psychology. If anything psychology should be higher, at least they can in principle have more reasonably-sized samples, but I won't argue the point, they're within a standard deviation of shit either way.
