I may have the answer: no, not directly.
Sage includes Pynac, which wraps GiNaC. GiNaC has indexed
expressions, which just might do exactly what I want. (I don't have
ginsh running to test differentiation.) But it looks like indexed
expressions are not hooked up for use in Sage. I am posting t

Sure. Here you have some tips:
{{{id=1|
#Create n variables with names x1, x2 ... xn
#and store them in a list vs
n = 5
vs = var(' '.join('x%d'%j for j in range(5)))
vs

}}}

return prod(v^d for v,d in zip(vs,ds))

I have a bevy of algebra/calculus to work through for my research. I
have been using Sage to check my derivation for specific instances,
but it would be great if Sage could help me *derive* the results in
the first place.
Here is a simplified example. (Hopefully the mixed math/LaTeX/Sage
syntax

Hello ,
I want to ask if there is build in method to use pretty print in full
output .
i.e (when I do some long calculations the output will truncated , and
the pretty print does not render in full output )
thanks

Dear all,
As reported in

the control sequence \texttt leads to an error in Jsmath. This is
supposed to be solved in Sage 4.4, but when I use html.table() to
display
