Thanks for the reply. If I want plot an algebraic curve using SAGE, what should I do then? Any suggestion? Pong On Sep 20, 1:58 pm, mabshoff <[EMAIL PROTECTED] dortmund.de> wrote: > On Sep 20, 11:37 am, pong <[EMAIL PROTECTED]> wrote: > > Hi Pong, > > > > > I tried the example > > > sage: s

I tried the example sage: s = singular.eval sage: s('LIB "surf.lib";') ... sage: s("ring rr0 = 0,(x1,x2),dp;") ... sage: s("ideal I = x1^3 - x2^2;") '' sage: s("plot(I);") in http://www.dms.umontreal.ca/~math/logiciels/Sage/const/node18.html#ch:AG Looks like surf has been load

This is not a bug report. But I'm not sure where to post a suggestion. In the SAGE tutorial, http://www.sagemath.org/doc/tut/node27.html there is an example: sage: c = factorial(25); c 1551121004333098598400 sage: [valuation(c,p) for p in prime_range(2,23)] [22, 10, 6, 3, 2, 1, 1, 1] Since
