Whatever LaTeX does by default

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

Are those called limits in English? How do you call those things then?

lim x->0 1/x

Better question: Where do you put the dx?

A fits on paper much better than B, especially when you try to write as small as possible to fit all of your work 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 ∫

Know your limit

The kerning on Latex integrals has always bothered me. The f(x) could move a LOT further to the left!

a sits on the dooblydoo on the left, b hangs from the dooblydoo on the right.

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.

Depends on if I accidentally wrote the function too large

A gang. Does that mean I am old?

ConTeXt has some nice new features: https://www.pragma-ade.com/general/manuals/mathincontext-screen.pdf#page87

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.
