In Debian aptitiude, I installed libiml0 and libiml-dev. After intalling

I don't understand this behavior:

2*x

Is the idea that the variable names [a-z] have been predefined for
convenience, but all others need to be explicitly defined before being
used?

1. How do you do scatter plots in SAGE, without using an interface to
underlying commercial software like MATLAB?
2. Can maxima or another tool compute [partial] derivatives or
integrals containing arithmetic sums or products?
