We're on symbolic integration techniques in my Calc II class right now, and SAGE rather nicely deals with many (but not all) of the standard examples, or makes the usual mistakes various other systems make (e.g., integrate(1/x) gives ln(x), not ln(abs(x))).
However, I'm stumped as to where this one comes from: integrate(1/sqrt(9+x^2)) x/3 I tried this at home and numerous times on sagenb.org. Every other plausible syntax of this integral I tried (-1 power, more parentheses, switch the summands, etc.) yields the same result. Yet surprisingly ;) I get derivative(x/3) 1/3 Any ideas? --~--~---------~--~----~------------~-------~--~----~ 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/ -~----------~----~----~----~------~----~------~--~---
