Whatever LaTeX does by default

[–] PM_ME_VINTAGE_30S@lemmy.sdf.org 50 points 4 months ago

LaTeX: typically let software decide for me, override if it looks bad.

Paper: Too shit at writing to make a consistent choice

[–] TheFriendlyDickhead@lemm.ee 25 points 4 months ago (2 children)

B. A only when there is little space

[–] hihi24522@lemm.ee 7 points 4 months ago

Same, but there is never enough space

[–] smeg@feddit.uk 6 points 4 months ago

Same. B if I'm feeling fancy, A if I'm trying to fit everything on one line.

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

lim x->0 1/x

[–] PM_ME_VINTAGE_30S@lemmy.sdf.org 20 points 4 months ago

For integrals, we would say that "b and a are the limits of integration".

The notation "lim x->0 1/x" would be read as "the limit of 1 over x as x goes to zero." In general, "lim" is short for "limit" of whatever follows it, with respect to what is below the "lim" symbol. Rarely, I have also seen the notation "l.i.m." used for the limit in mean, i.e. the limit with respect to the L^2 norm.

Also limits. But also "tends towards".

[–] howrar@lemmy.ca 13 points 4 months ago (2 children)

Better question: Where do you put the dx?

[–] Mubelotix@jlai.lu 5 points 4 months ago (2 children)

What? Where else would you put it?

[–] HeyThisIsntTheYMCA@lemmy.world 8 points 4 months ago

Wherever you want it baby

[–] qjkxbmwvz@startrek.website 5 points 4 months ago (1 children)

Immediately after the integral symbol, before the integrand, is also common: https://math.stackexchange.com/questions/1146345/notational-position-of-dx-in-integral

It has a nice "operator" look this way.

[–] Mubelotix@jlai.lu 1 points 4 months ago

I would interpret this completely differently than what was intended

[–] Car@lemmy.dbzer0.com 11 points 4 months ago

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

[–] lugal@sopuli.xyz 8 points 4 months ago

Know your limit

[–] Zagorath@aussie.zone 8 points 4 months ago (1 children)

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 ∫

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

[–] oxideseven@lemmy.ca 6 points 4 months ago

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

[–] model_tar_gz@lemmy.world 6 points 4 months ago* (last edited 4 months ago)

+ C: I’m so indefinite, I don’t respect limits.

[–] Feathercrown@lemmy.world 6 points 4 months ago

A, B takes too much space

[–] Brickardo@feddit.nl 6 points 4 months ago* (last edited 4 months ago) (1 children)

(a, b) at the bottom. It's a 1d integral, so nothing goes after f as well for me.

[–] PM_ME_VINTAGE_30S@lemmy.sdf.org 2 points 4 months ago* (last edited 4 months ago)

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.

[–] sharkfucker420@lemmy.ml 4 points 4 months ago

Depends on if I accidentally wrote the function too large

[–] collapse_already@lemmy.ml 3 points 4 months ago

A gang. Does that mean I am old?

[–] jmcr@lemmy.ml 2 points 4 months ago* (last edited 4 months ago)
[–] rustyfish@lemmy.world 1 points 4 months ago

Always A. Except when I’m drunk.

[–] Iron_Lynx@lemmy.world 1 points 3 months ago

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.
