Hi, I am preparing patches that will resolve
http://trac.sagemath.org/sage_trac/ticket/6465 and will also move symbolic integration as a sub-class of SFunction into new symbolics. Currently, Sage allows omitting variable of integration for convenience. However, this convenience comes at a hefty price by making Sage syntax highly inconsistent. On top of this, it mask genuine typing error as a valid input. For example: "integrate(f(x), x, a, )" is treated as "integrate(f(x), x, x, a)" where user may have wanted to type "integrate(f(x), x, a, b)" but missed the "b". Given we are moving to a new settings, I am proposing that we make integration syntax bit stricter and consistent now. In particular, we allow only following inputs as valid (1) integrate( f(x), x) (2) integrate( f(x), (x,a,b) ) (3) integrate( f(x), x, a, b) Cheers, Golam --~--~---------~--~----~------------~-------~--~----~ To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an 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 -~----------~----~----~----~------~----~------~--~---
