| Dec 2, 2017 at 1:39 | comment | added | LSpice | @AndreasBlass, hah, very nice! Indeed, once I know the answer I can justify it ex post facto, but unfortunately that doesn't help me personally remember, as @RodrigoA.Pérez puts it, whether to look "from above" or "from below". Maybe thinking of it as looking up will help. | |
| Dec 1, 2017 at 23:55 | comment | added | Andreas Blass | @LSpice Instead of looking it up, you could just look up (i.e., look at the graph from below) and you'd have the standard convention. | |
| Nov 29, 2017 at 18:59 | comment | added | LSpice | I can never remember which way this goes without looking it up, but are there really varying conventions in upper-level mathematics (as opposed to calculus textbooks)? I thought one spoke exclusively about convex functions in, say, measure theory. | |
