i have a question about a polynomial ring over a polynomial ring. suppose i have
R1.<w> = QQ['w'] R2.<z> = R1['z'] and i construct some sort of element, f = z*w i know that if i want to evaluate z, i can do something like f(1) # output: w and even f(1)(5) # same as w(5) . the question is: how do i evaluate w while leaving z untouched? (i actually want to do this when R1 is a multivariable ring, but i imagine it works the same way.) thanks, kyle --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://sage.math.washington.edu/sage/ and http://sage.scipy.org/sage/ -~----------~----~----~----~------~----~------~--~---
