LaTeX: typically let software decide for me, override if it looks bad.
Paper: Too shit at writing to make a consistent choice
B. A only when there is little space
Same, but there is never enough space
Same. B if I’m feeling fancy, A if I’m trying to fit everything on one line.
Out of these? I’m team Blue.
But really, I’m team Green. b goes more or less in the place Red shows it (or maybe halfway between where Red and Blue show it), but a goes to the left of the integration symbol, mirroring where the b goes relative to the curve at the end of the ∫
Comrade!
The kerning on Latex integrals has always bothered me. The f(x) could move a LOT further to the left!
Know your limit
A, B takes too much space
+ C: I’m so indefinite, I don’t respect limits.
(a, b) at the bottom. It’s a 1d integral, so nothing goes after f as well for me.
Best answer, although I work with delta “functions” a lot so I actually have to be careful picking which interval with boundary {a,b} to pick (for example, if I integrated δ(t-a)+δ(t-b) over all t in (a,b), I’d get 0, but if I integrated those deltas over (a,b] I’d get 1, and integrating over [a,b] would give 2).
Also I do have to do integrals with parameters and multiple variables so I can’t really leave out the differential.
Always A. Except when I’m drunk.
If a and b are simply numbers or variables (ex. 1, 2π, x), either, maybe red.
If a or b is a function (ex. (x + y), (1/N), (z - r²)), then blue.
