06:30 <holst> how can I make an external function declaration and source it in maxima?

06:50 <holst> cool =D
06:50 <holst> I saved the file in ~/.maxima and then it finds it

11:56 <holst> hmm
11:56 <holst> I try and run this program (NEWTON)
11:56 <holst> http://www.delorie.com/gnu/docs/maxima/maxima_124.html
11:56 <holst> but it says: http://www.delorie.com/gnu/docs/maxima/maxima_124.html
11:56 <holst> hmm, wrong paste
11:57 <holst> Incorrect syntax: Y is not an infix operator

12:53 <HaraldG> holst: The syntax in this file is really old.
12:53 <HaraldG> Maxima is case sensitive now.
12:53 <HaraldG> Thus you have to write if, do, ... all in lower case.

16:14 <milian> is it possible to assign a term to a user defined variable?
16:14 <milian> something like:
16:14 <milian> a := 5
16:14 <milian> b := 2 - a // = -3
16:30 <faroe> milian: a : 5;
16:30 <milian> ty
16:30 <milian> that works like a charm
16:31 <faroe> milian: := is used for function definitions, e.g. f(x) := 2*x;
16:31 <milian> now another question: Is there a function to get the norm of a vector?
16:31 <milian> I hope its called norm ;-)
16:31 <milian> what I mean is:
16:31 <milian> sqrt(a.a)
16:31 <milian> or do I have to type it that way all along?
16:34 <faroe> milian: there probably is, try running ?? norm
16:36 <milian> faroe: Could not find `/usr/share/info/maxima-index.lisp' using paths in file_search_lisp,system
16:36 <milian> I'm running ubuntu... damnit ;-)
16:36 <milian> ah I see
16:36 <milian> they gzipped that file.....
16:37 <faroe> milian: perhaps apt-get install maxima-doc is needed
16:38 <milian> I already looked, it's installed...
16:50 <milian> I fixed it, but cant find anything apropriate
16:50 <milian> well, nevermind
16:50 <milian> I'll stick to sqrt(a.a) then
16:51 <faroe> milian: you can just define it as a function
16:51 <faroe> milian: i.e. norm(a) := sqrt(a.a);
16:52 <milian> ha, thats good thank you very much
16:52 <faroe> milian: np

17:51 <sebbar> hi if I write p = cos(a)^2; q = sin(a)^2; p+q
17:51 <sebbar> I get as result p+q
17:51 <sebbar> how do I simplify that to 1?

19:42 <milian> sebbar: use a colon instead of the equal sign
19:42 <milian> p : cos(a)^2
19:42 <milian> etc.
