+1 for consistency.
However, you should really get rid of these evil coefficients,
then you can use term as synonym for monomial ;-).

I have some evening plans but I think I might head there earlier on
Thursday, around 4. The Moscone wifi is truly sad.

Seriously though, the best combination of location, hours and wifi
I've found is Seattle's Best Coffee in Borders Books in the Westfield
San Francisco Centre. Open until 10 PM, with free wifi.
I am interested. The wireless at the Moscone is pathetic, so maybe we
should arrange time and place to meet tonight (as I am basically
cutoff from the net all day).

I agree with your proposed terminology for term, coefficient and
monomial. Though I would only have used the word "monomial" for a
polynomial algebra when thought of as a module, otherwise just
"generator" or similar.

Hello all,
Sage changes expression which is converted from Maxima. As a
consequence, the linear term in taylor polynomial is allway expanded
into f'(a)*x+const instead of f'(a)*(x-a)+f(a).
Can someone explain this behavior? How to get rid of this?

Hello all,
I'm currently working on enriching the ModulesWithBasis Category in
Sage, and I have a question about what to call things. Namely, when
given a sum of generators with coefficients, what is a 'term' and what
is a 'monomial'. (Typically, I am asking for leading/trailing
terms/monomials)

Big speed improvements on calculations involving small finite fields,
like finding primitive elements? Possibility for automatic coercion
for finite fields? And the cost is just 0.5MB of harmless plain text
that doesn't even need to be compiled!?
