Happy to read this but this doesn't work on our server :-(
We installed LON-CAPA 2.4.0 on our Fedora 5 server and checked the new
problem templates. All these problems which use maxima are NOT working:
1) Formula Response using Computer Algebra System:
ERROR:Computer's answer is incorrect ("5*a*x^4").
2) Formula Response using Computer Algebra System and Hints:
ERROR:Computer's answer is incorrect ("16t^3,42t^6").
3) Math Response using Computer Algebra System and Hints:
Feedback message: "Unable to understand formula"
Maxima details (called maxima via shell):
Maxima 5.11.0 http://maxima.sourceforge.net
Using Lisp GNU Common Lisp (GCL) GCL 2.6.7 (aka GCL)
We are concerned that the old issues with wrong lisp version, Expect.pm
etc. still might exist.
What do you think? What do you know?
