Hello, does anyone knows how to access the formula parse tree I found sth similar what I want in java.. http://www.singularsys.com/jep/doc/html/advanced.html
what I really want, is to make derivative exercise tool.. which would do the differentiation of (complex) formulas step by step acctually I would need a parse tree according to one given variable, let's say _x_ where the each depth-node would mean one of known derivative formulas and + would be parallel/linear node http://en.wikipedia.org/wiki/Derivative#Rules_for_finding_the_derivative sin(2*x) + x^2 should give: + sin->*2->x + ^2 -> x having this form, I could handle derivation steps flexibly.. :) I know python has powerfull parse tools, but I don't want to invent bicycle, I'd rather hack it :) I found some abandoned project http://www.strout.net/python/pythonica.html but I hope if not sage, then mayby Axiom or Maxima has sth similar.. Thanks for the answers in adwance :) ps.: there's still some thoughts about f(x)*g(x), which should be worked out as f'*g + f*g' and i still don't quite know/remember how to handle x^x --~--~---------~--~----~------------~-------~--~----~ 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/ -~----------~----~----~----~------~----~------~--~---
