You're right, it does not use partial for a single variable, even through Sage. sage: m = maxima('integrate(sin(x^3),x)') sage: m 'integrate(sin(x^3),x) sage: m._latex_() '\\int {\\sin x^3}{\\;dx}' sage: latex(integrate(sin(x^3),x)) \int {\sin x^3}{\;dx} William --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
