hello list,
here is a simple maxima session I've worked on:
(%i1) load(stopex);
Warning - you are redefining the Maxima function intersection
(%o1) /home/matt/Works/maxima-5.9.3/share/simplification/stopex.mac
(%i2) eq: x*(a+b)+y*(c+d);
(%o2) (d + c) y + (b + a) x
(%i4) expand(eq);
(%o4) d y + c y + b x + a x
(%i6) expandwrt(eq,x);
(%o6) (d + c) y + (b + a) x
I installed maxima from the source code (O.S: debian GNU/Linux 3.1
etch/sid, maxima-5.9.3.tar.gz, clisp 2.38-6) and my questions are the
followings:
1) Why did I receive that Warning?
2) I expected the following result from expandwrt function
(%o6) (d + c) y + b x + a x
but it seems my expandwrt doesn't work. Why?
thanks in advance !
matt
