The behavior of show could be improved using assume.

Start with:

x = var('x')
f(x) = 1 - x
assume(x < 1, x > 0)

The current behavior is that show(f) will output x - 1, whereas a human mathematician would always write this as 1 - x.

  • Milestone sage-8.8 deleted

As the Sage-8.8 release milestone is pending, we should delete the sage-8.8 milestone for tickets that are not actively being worked on or that still require significant work to move forward. If you feel that this ticket should be included in the next Sage release at the soonest please set its milestone to the next release milestone (sage-8.9).

Note: See TracTickets for help on using tickets.
