The theory of Kaehler differentials does a pretty good job providing differential calculus with sound algebraic footing and it is intentional that the terminology mixes derivation and differentials. One would really only need to prove a few universality properties at the start of an introductory calculus course to have it make perfect mathematical sense (but not necessarily to the students) without having to introduce any epsilons or deltas.
The term "Goppa polynomial" leads me to suspect that the OP had coding theoretic and hence probably quite algebraic intentions, so he/she probably is better off looking at polynomial rings rather than "symbolic expressions". -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
