Calculus is actual calculus. Symbolics is exposing symbolics of
Maxima, Pynac etc. to users in the rest of Sage. So, for instance, R.
Marik's question about getting Maxima's "1#0" to turn into "1!=0" is a
symbolics issue, and so is something getting SR to do stuff like have
a vector in SR use subs correctly. Fixing an integration bug or
implementing quick non-Maxima-based differentiation of something or
other would be calculus.
Obviously many of these could also fit into another box - anything
Maxima could be about a package or an interface - but I, at least,
found it helpful to have the distinction available for tickets which
were about the things which allowed calculus functionality to happen
but were not really at all about calculus.
Really, it's all about making it easy to search the 1000 or so open
tickets in Sage! Apropos of that, being able to specify multiple
components would also be nice, but probably that's not possible (?) or
it would have already been done. For instance, something could be a
porting issue but also a geometry issue, if there is a port that
behaves badly with respect to a certain polytope computation.
Hope that clarifies it - thanks for considering it.
