It seems that by cutting and pasting I mangled the text. Sorry. Here is the relevant part of the sage session: In [99]: limit(sqrt(x^2 + x +1) + x, x = -oo) [...] error message ending in Is x positive or negative? In [100]: assume(x > 0) In [101]: limit(sqrt(x^2 + x +1) + x, x = -oo) [...] same error message as before In [102]: sqrt(x^2) Out[102]: -x In [103]: forget() In [104]: sqrt(x^2) Out[104]: abs(x) Nikos --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to [email protected] 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/ -~----------~----~----~----~------~----~------~--~---
